That only Man hath an Erect figure, and for to behold and look up toward heaven, according to that of the Poet,
is a double assertion, whose first part may be true, if we take Erectness strictly, and so as Galen hath defined it; for they only, saith he, have an Erect figure, whose spine and thigh-bone are carried in right lines; and so indeed of any we yet know, Man only is Erect. For the thighs of other animals do stand at Angles with their spine, and have rectangular positions in Birds, and perfect Quadrupeds. Nor doth the Frog, though stretched out, or swimming, attain the rectitude of Man, or carry its thigh without all angularity. What seiante or sitting. And thus is it also true, that Man only sitteth, if we define sitting to be a firmation of the body upon the Ischias: wherein if the position be just and natural, the Thigh-bone lieth at right angles to the Spine, and the Leg-bone or Tibia to the Thigh. For others when they seem to sit, as Dogs, Cats, or Lions, do make unto their Spine acute angles with their Thigh, and acute to the Thigh with their Shank. Thus is it likewise true, what Aristotle alledgeth in that Problem; why Man alone suffereth pollutions in the Night, ἐξονειρωκτικός. because Man only lyeth upon his Back; if we define not the same by every supine position, but when the Spine is in rectitude with the Thigh, and both with the arms lie parallel to the Horizon: so that a line through their Navel will pass through the Zenith and Centre of the Earth. And so cannot other Animals lie upon their Backs: for though the Spine lie parallel with the Horizon, yet will their Legs incline, and lie at angles unto it. And upon these three divers positions in Man, wherein the Spine can only be at right lines with the Thigh, arise those remarkable postures, prone, supine and erect; which are but differenced in situation, or in angular postures upon the Back, the Belly and the Feet.
But if Erectness be popularly taken, and as it is largely opposed unto proneness, or the posture of animals looking downwards, carrying their venters or opposite part to the Spine, directly towards the Earth, it may admit of question. For though in Serpents and Lizards we may truly allow a proneness, yet Galen acknowledgeth that perfect Quadrupeds, as Horses, Oxen and Camels, are but partly prone, and have some part of Erectness. And Birds or flying Animals, are so far from this kind of proneness, that they are almost Erect; advancing the Head and Breast in their progression, and only prone in the Act of volitation or flying. And if that be true which is delivered of the Pengin or Anser Magellanicus, often described in Maps about those Straits, that they go Erect like Men, and with their Breast and Belly do make one line perpendicular unto the axis of the Earth; it will almost make up the exact Erectness of Man. Observe also the Vrias Bellanii and Mergus major. Nor will that Insect come very short which we have often beheld, that is, one kind of Locust which stands not prone, or a little inclining upward, but in a large Erectness, elevating alwaies the two fore Legs, and sustaining it self in the middle of the other four: by Zoographers Describers of animals. called Mantis, and by the common people of Provence, Prega, Dio, the Prophet and praying Locust; as being generally found in the posture of supplication, or such as resembleth ours, when we lift up our hands to Heaven.
As for the end of this Erection; to look up toward Heaven; though confirmed by several testimonies, and the Greek Etymology of Man, it is not so readily to be admitted; and as a popular and vain conceit was Anciently rejected by Galen; who in his third, De usu partium, determines, that Man is Erect, because he was made with hands, and was therewith to exercise all Arts, which in any other figure he could not have performed; as he excellently declareth in that place, where he also proves that Man could have been made neither Quadruped nor Centaur.
And for the accomplishment of this intention, that is, to look up and behold the Heavens, Man hath a notable disadvantage in the Eye lid; whereof the upper is far greater than the lower, which abridgeth the sight upwards; contrary to those of Birds, who herein have the advantage of Man: Insomuch that the Learned PlempiusPlemp. Ophthalmographia. is bold to affirm, that if he had had the formation of the Eye-lids, he would have contrived them quite otherwise.
The ground and occasion of this conceit was a literal apprehension of a figurative expression in Plato, as Galen thus delivers; To opinion that Man is Erect to look up and behold the Heavens, is a conceit only fit for those that never saw the Fish Uranoscopus, that is, the Beholder of Heaven; which hath its Eyes so placed, that it looks up directly to Heaven; which Man doth not, except he recline, or bend his head backward: and thus to look up to Heaven, agreeth not only unto Men, but Asses; to omit Birds with long necks, which look not only upwards, but round about at pleasure. And therefore Men of this opinion understood not Plato when he said that Man doth Sursum aspicere; for thereby was not meant to gape, or look upward with the Eye, but to have his thoughts sublime; and not only to behold, but speculate their Nature, with the Eye of the understanding.
Now although Galen in this place makes instance but in one, yet are the other fishes, whose Eyes regard the Heavens, as Plane, and Cartilagineous Fishes; as Pectinals, or such as have their bones made laterally like a Comb; for when they apply themselves to sleep or rest upon the white side, their Eyes on the other side look upward toward Heaven. For Birds, they generally carry their heads Erectly like Man, and have advantage in their upper Eye-lid; and many that have long necks, and bear their heads somewhat backward, behold far more of the Heavens, and seem to look above the æquinoxial Circle. And so also in many Quadrupeds, although their progression be partly prone, yet is the sight of their Eye direct, not respecting the Earth but Heaven; and make an higher Arch of altitude then our own. The position of a Frog with his head above water exceedeth these; for therein he seems to behold a large part of the Heavens, and the acies of his Eye to ascend as high as the Tropick; but he that hath beheld the posture of a Bittor, will not deny that it beholds almost the very Zenith. Point of heaven over our heads.
That the Heart of Man is seated in the left side, is an asseveration, which strictly taken, is refutable by inspection, whereby it appears the base and centre thereof is in the midst of the chest; true it is, that the Mucro or Point thereof inclineth unto the left; for by this position it giveth way unto the ascension of the midriff, and by reason of the hollow vein could not commodiously deflect unto the right. From which diversion, nevertheless we cannot so properly say tis placed in the left, as that it consisteth in the middle, that is, where its centre resteth; for so do we usually say a Gnomon or Needle is in the middle of a Dial, although the extreams may respect the North or South, and approach the circumference thereof.
The ground of this mistake is a general observation from the pulse or motion of the Heart, which is more sensible on this side; but the reason hereof is not to be drawn from the situation of the Heart, but the site of the left ventricle wherein the vital Spirits are laboured; and also the great Artery that conveieth them out; both which are situated on the left. Upon this reason Epithems or cordial Applications are justly applied unto the left Breast; and the Wounds under the fifth Rib may be more suddenly destructive if made on the sinister side, and the Spear of the Souldier that peirced our Saviour, is not improperly described, when Painters direct it a little towards the left.
The other ground is more particular and upon inspection; for in dead Bodies especially lying upon the Spine, the Heart doth seem to incline unto the left. Which happeneth not from its proper site; but besides its sinistrous gravity, is drawn that way by the great Artery, which then subsideth and haleth the Heart unto it. And therefore strictly taken, the Heart is seated in the middle of the Chest; but after a careless and inconsiderate aspection, or according to the readiest sense of pulsation, we shall not quarrel, if any affirm it is seated toward the left. And in these considerations must Aristotle be salved, when he affirmeth the Heart of Man is placed in the left side, and thus in a popular acception may we receive the Periphrasis of Persius; ——Leva in parte mamillæ. when he taketh the part under the left Pap for the Heart; and if rightly apprehended, it concerneth not this controversie, when it is said in Ecclesiastes: The Heart of a wise Man is in the right side, but that of a Fool in the left, for thereby may be implied, that the Heart of a wise Man delighteth in the right way, or in the path of Vertue; that of a Fool in the left or road of Vice; according to the mystery of the Letter of Pythagoras, or that expression in Jonah, concerning sixscore thousand, that could not discern between their right hand and their left, or knew not good from evil.
That assertion also that Man proportionally hath the largest brain, I did I confess somewhat doubt; and conceived it might have failed in Birds, especially such as having little Bodies, have yet large Cranies, and seem to contain much Brain, as Snipes, Woodcocks, etc. But upon trial I find it very true. The Brains of a Man, Archangelus and Bauhinus observe, to weigh four pound, and sometime five and a half. If therefore a Man weigh one hundred and fourty pounds, and his Brain but five, his Weight is 27. times as much as his brain, deducting the weight of that five pound which is allowed for it. Now in a Snipe, which weighed four ounces two dragms, I find the Brains to weigh but half a dragm; so that the weight of the Body (allowing for the Brain) exceeded the weight of the Brain, sixty seven times and an half.
More controvertible it seemeth in the Brains of Sparrows, whose Cranies are rounder, and so of larger capacity: and most of all in the Heads of Birds, upon the first formation in the Egg, wherein the Head seems larger then all the Body, and the very Eyes almost as big as either. A Sparrow in the total we found to weigh seven dragms and four and twenty grans; whereof the Head a dragm, but the Brain not fifteen grains; which answereth not fully the proportion of the brain of Man. And therefore it is to be taken of the whole Head with the Brains, when Scaliger Histor. Animal. lib. 1. objecteth that the Head of a Man is the fifteenth part of his Body; that of a Sparrow, scarce the fifth.
That Pleurisies are only on the left side, is a popular Tenent not only absurd but dangerous. From the misapprehension hereof, men omitting the opportunity of remedies, which otherwise they would not neglect. Chiefly occasioned by the Ignorance of Anatomy and the extent of the part affected; which in an exquisite Pleurisie is determined to be the skin or membrane which invested the Ribs, for so it is defined, Inflammatio membranæ costas succingentis; An Inflammation, either simple, consisting only of an hot and sanguineous affluxion; or else denominable from other humours, according to the predominancy of melancholy, flegm, or choler. The membrane thus inflamed, is properly called Pleura; from whence the disease hath its name; and this investeth not only one side, but overspreadeth the cavity of the chest, and affordeth a common coat unto the parts contained therein.
Now therefore the Pleura being common unto both sides, it is not reasonable to confine the inflammation unto one, nor strictly to determine it is alwaies in the side; but sometimes before and behind, that is, inclining to the Spine or Breast-bone; for thither this Coat extendeth; and therefore with equal propriety we may affirm, that ulcers of the lungs, or Apostems of the brain do happen only in the left side; or that Ruptures are confinable unto one side, whereas the Peritoneum or Rib of the Belly may be broke, or its perforations relaxed in either.
An opinion there is, which magnifies the fourth Finger of the left Hand; presuming therein a cordial relation, that a particular vessel, nerve, vein or artery is conferred thereto from the heart, and therefore that especially hath the honour to bear our Rings. Which was not only the Christian practice in Nuptial contracts, but observed by Heathens, as Alexander ab Alexandro, Gellius, Macrobius and Pierius have delivered, as Levinus Lemnius hath confirmed, who affirms this peculiar vessel to be an artery, and not a Nerve, as Antiquity hath conceived it; adding moreover that Rings hereon peculiarly affect the Heart; that in Lipothymies or swoundings he used the frication of this Finger with saffron and gold: that the ancient Physitians mixed up their Medicines herewith; that this is seldom or last of all affected with the Gout, and when that becometh nodous, Men continue not long after. Notwithstanding all which we remain unsatisfied, nor can we think the reasons alleadged sufficiently establish the preheminency of this Finger.
For first, Concerning the practice of Antiquity, the custom was not general to wear their Rings either on this hand or Finger; for it is said, and that emphatically in Jeremiah, Si fuerit Jeconias filius Joachim regis Judæ annulus in manu dextrâ meâ, inde evallam eum: Though Coniah the son of Joachim King of Judah, were the signet on my right Hand, yet would I pluck thee thence. So is it observed by Pliny, that in the portraits of their Gods, the Rings were worn on the Finger next the Thumb; that the Romans wore them also upon their little Finger, as Hero is described in Petronius; some wore them on the middle Finger, as the ancient Gaules and Britans; and some upon the fore-Finger, as is deduceable from Julius Pollux: who names that Ring Corionos.
Again, That the practice of the ancients, had any such respect of cordiality or reference unto the Heart, will much be doubted, if we consider their Rings were made of iron; such was that of Prometheus, who is conceived the first that brought them in use. So, as Pliny affirmeth, for many years the Senators of Rome did not wear any Rings of Gold; but the slaves wore generally Iron Rings until their manumission or preferment to some dignity. That the Lacedemonians continued their Iron Rings unto his daies, Pliny also delivereth, and surely they used few of Gold; for beside that Lycurgus prohibited that mettal, we read in Athenæus, that having a desire to guild the face of Apollo, they enquired of the Oracle where they might purchase so much Gold; and were directed unto Crœsus King of Lydia.
Moreover whether the Ancients had any such intention, the grounds which they conceived in Vein, Nerve or Artery, are not to be justified, nor will inspection confirm a peculiar vessel in this Finger. For as Anatomy informeth, the Basilica vein dividing into two branches below the cubit, the outward sendeth two surcles unto the thumb, two unto the fore-finger, and one unto the middle finger in the inward side; the other branch of the Basilica sendeth one surcle unto the outside of the middle finger, two unto the Ring, and as many unto the little fingers; so that they all proceed from the Basilica, and are in equal numbers derived unto every one. In the same manner are the branches of the axillary artery distributed into the Hand; for below the cubit it divideth into two parts, the one running along the Radius, and passing by the wrest or place of the pulse, is at the Fingers subdivided into three Branches; whereof the first conveyeth two surcles unto the Thumb, the second as many to the fore-Finger, and the third one unto the middle Finger; the other or lower division of the artery descendeth by the ulna, and furnisheth the other Fingers; that is the middle with one surcle, and the Ring and little Fingers with two. Whence the Nerves proceed. As for the Nerves, they are disposed much after the same manner, and have their original from the Brain, and not the Heart, as many of the Ancients conceived; which is so far from affording Nerves unto other parts, that it receiveth very few it self from the sixth conjugation, or pair of Nerves in the Brain.
Lastly, These propagations being communicated unto both Hands, we have no greater reason to wear our Rings on the left, then on the right; nor are there cordial considerations in the one, more then the other. And therefore when Forestus for the stanching of blood makes use of Medical applications unto the fourth Finger, he confines not that practice unto the left, but varieth the side according to the nostril bleeding. So in Feavers, where the Heart primarily suffereth, we apply Medicines unto the wrests of either arm; so we touch the pulse of both, and judge of the affections of the Heart by the one as well as the other. And although in indispositions of Liver or Spleen, considerations are made in Phlebotomy respectively to their situation; yet when the Heart is affected, Men have thought it as effectual to bleed on the right as the left; and although also it may be thought, a nearer respect is to be had of the left, because the great artery proceeds from the left ventricle, and so is nearer that arm; it admits not that consideration. For under the channel bones the artery divideth into two great branches, from which trunk or point of division, the distance unto either Hand is equal, and the consideration also answerable.
All which with many respective Niceties, in order unto parts, sides, and veines, are now become of less consideration, by the new and noble doctrine of the circulation of the blood.
And therefore Macrobius discussing the point, hath alleadged another reason; affirming that the gestation of Rings upon this Hand and Finger, might rather be used for their conveniency and preservation, then any cordial relation. For at first (saith he) it was both free and usual to wear Rings on either Hand; but after that luxury encreased, when pretious gems and rich insculptures were added, the custom of wearing them on the right Hand was translated unto the left; for that Hand being less imployed, thereby they were best preserved. And for the same reason they placed them on this Finger; for the Thumb was too active a Finger, and is commonly imployed with either of the rest: the Index or fore-Finger was too naked whereto to commit their pretiosities, and hath the tuition of the Thumb scarce unto the second joint: the middle and little Finger they rejected as extreams, and too big or too little for their Rings, and of all chose out the fourth, as being least used of any, as being guarded on either side, and having in most this peculiar condition, that it cannot be extended alone and by itself, but will be accompanied by some Finger on either side. And to this opinion assenteth Alexander ab Alexandro, Annulum nuptialem prior ætas in sinistrâ ferebat, crediderim ne attereretur.
Now that which begat or promoted the common opinion, was the common conceit that the Heart was seated on the left side; but how far this is verified, we have before declared. The Egyptian practice hath much advanced the same, who unto this Finger derived a Nerve from the Heart; and therefore the Priest anointed the same with precious oyls before the Altar. But how weak Anatomists they were, which were so good Embalmers, we have already shewed. And though this reason took most place, yet had they another which more commended that practice: and that was the number whereof this Finger was an Hieroglyphick. For by holding down the fourth Finger of the left Hand, while the rest were extended, they signified the perfect and magnified number of six. For as Pierius hath graphically declared, Antiquity expressed numbers by the Fingers of either Hand: on the left they accounted their digits and articulate numbers unto an hundred; on the right Hand hundreds and thousands; the depressing this Finger, which in the left Hand implied but six, in the right indigitated six hundred. In this way of numeration, may we construe that of Juvenal concerning Nestor,
And however it were intended, in this sense it will be very elegant what is delivered of Wisdom, Prov. 3. Length of daies is in her right Hand, and in her left Hand riches and honour.
As for the observation of Lemnius an eminent Physitian, concerning the Gout; however it happened in his Country, we may observe it otherwise in ours; that is, that chiragrical persons do suffer in this Finger as well as in the rest, and sometimes first of all, and sometimes no where else. And for the mixing up medicines herewith; it is rather an argument of opinion, then any considerable effect; and we as highly conceive of the practice in Diapalma, that is, in the making of that plaister, to stir it with the stick of a Palm.
It is also suspicious, and not with that certainty to be received, what is generally believed concerning the right and left hand; that Men naturally make use of the right, and that the use of the other is a digression or aberration from that way which nature generally intendeth. We do not deny that almost all Nations have used this hand, and ascribed a preheminence thereto: hereof a remarkable passage there is in the 48. of Genesis, And Joseph took them both, Ephraim in his right hand towards Israels left hand, and Manasses in his left hand towards Israels right hand, and Israel stretched out his right hand and laid it upon Ephraims head, who was the younger, and his left hand upon Manasses head, guiding his hands wittingly, for Manasses was the first-born; and when Joseph saw that his father laid his right hand upon the head of Ephraim, it displeased him, and he held up his fathers hand to remove it from Ephraims head unto Manasses head, and Joseph said, Not so my father, for this is the first-born, put thy right hand upon his head: The like appeareth from the ordinance of Moses in the consecration of their Priests, Then shalt thou kill the Ram, and take of his blood, and put it upon the tip of the right ear of Aaron, and upon the tip of the right ear of his sons, and upon the thumb of the right hand, and upon the great toe of the right foot, and sprinkle the blood on the Altar round about. That the Persians were wont herewith to plight their faith, is testified by Diodorus: That the Greeks and Romans made use hereof, beside the testimony of divers Authors, is evident from their custom of discumbency at their meals, which was upon their left side, for so their right hand was free, and ready for all service. As also from the conjunction of the right hands and not the left observable in the Roman medals of concord. Nor was this only in use with divers Nations of Men, but was the custom of whole Nations of Women; as is deduceable from the Amazones in the amputation of their right breast, whereby they had the freer use of their bow. All which do seem to declare a natural preferment of the one unto motion before the other; wherein notwithstanding in submission to future information, we are unsatisfied unto great dubitation.
For first, if there were a determinate prepotency in the right, and such as ariseth from a constant root in nature, we might expect the same in other animals, whose parts are also differenced by dextrality; wherein notwithstanding we cannot discover a distinct and complying account; for we find not that Horses, Buls, or Mules, are generally stronger on this side. As for Animals whose forelegs more sensibly supply the use of arms, they hold, if not an equality in both, a prevalency oft-times in the other, as Squirrels, Apes, and Monkies; the same is also discernable in Parrets, who feed themselves more commonly by the left-leg, and Men observe that the Eye of a Tumbler is biggest, not constantly in one, but in the bearing side.
That there is also in Men a natural prepotency in the right, we cannot with constancy affirm, if we make observation in children; who permitted the freedom of both, do oft-times confine unto the left, and are not without great difficulty restrained from it. And therefore this prevalency is either uncertainly placed in the laterality, or custom determines its differency. Which is the resolution of Aristotle in that Problem, which enquires why the right side being better then the left, is equal in the senses? because, saith he, the right and left do differ by use and custom, which have no place in the senses. For right and left as parts inservient unto the motive faculty, are differenced by degrees from use and assuefaction, according whereto the one grows stronger and oft-times bigger then the other. But in the senses it is otherwise; for they acquire not their perfection by use or custom, but at the first we equally hear and see with one Eye, as well as with another. And therefore, were this indifferency permitted, or did not constitution, but nature determine dextrality, there would be many more Scevolaes then are delivered in story; nor needed we to draw examples of the left, from the sons of the right hand;Benjamin filius dextræ. as we read of seven thousand in the Army of the Benjamites. True it is, that although there be an indifferency in either, or a prevalency indifferent in one, yet is it most reasonable for uniformity, and sundry respective uses, that Men should apply themselves to the constant use of one; for there will otherwise arise anomalous disturbances in manual actions, not only in civil and artificial, but also in Military affairs, and the several actions of war.
Secondly, The grounds and reasons alleadged for the right, are not satisfactory, and afford no rest in their decision. Scaliger finding a defect in the reason of Aristotle, introduceth one of no less deficiency himself; Ratio materialis (saith he) sanguinis crassitudo simul et multitudo; that is, the reason of the vigour of this side, is the crassitude and plenty of blood; but this is not sufficient; for the crassitude or thickness of blood affordeth no reason why one arm should be enabled before the other, and the plenty thereof, why both not enabled equally. Fallopius is of another conceit, deducing the reason from the Azygos or vena sine pari, a large and considerable vein arising out of the cava or hollow vein, before it enters the right ventricle of the Heart, and placed only in the right side. But neither is this perswasory; for the Azygos communicates no branches unto the arms or legs on either side, but disperseth into the Ribs on both, and in its descent doth furnish the left Emulgent with one vein, and the first vein of the loins on the right side with another; which manner of derivation doth not confer a peculiar addition unto either. Cælius Rodiginus undertaking to give a reason of Ambidexters and Left-handed Men, delivereth a third opinion: Men, saith he, are Ambidexters, and use both Hands alike, when the heat of the Heart doth plentifully disperse into the left side, and that of the Liver into the right, and the spleen be also much dilated; but Men are Left-handed when ever it happeneth that the Heart and Liver are seated on the left-side; or when the Liver is on the right side, yet so obducted and covered with thick skins, that it cannot diffuse its vertue into the right. Which reasons are no way satisfactory; for herein the spleen is injustly introduced to invigorate the sinister side, which being dilated it would rather infirm and debilitate. As for any tunicles or skins which should hinder the Liver from enabling dextral parts; we must not conceive it diffuseth its vertue by meer irradiation, but by its veins and proper vessels, which common skins and teguments cannot impede. And for the seat of the Heart and Liver in one side, whereby Men become Left-handed, it happeneth too rarely to countenance an effect so common; for the seat of the Liver on the left side is monstrous, and rarely to be met with in the observations of Physitians. Others not considering ambidextrous and Left-handed Men, do totally submit unto the efficacy of the Liver; which though seated on the right side, yet by the subclavian division doth equidistantly communicate its activity unto either Arm; nor will it salve the doubts of observation; for many are Right-handed whose Livers are weakly constituted, and many use the left, in whom that part is strongest; and we observe in Apes, and other animals, whose Liver is in the right, no regular prevalence therein.
And therefore the brain, especially the spinal marrow, which is but the brain prolonged, hath a fairer plea hereto; for these are the principles of motion, wherein dextrality consists; and are divided within and without the Crany. By which division transmitting Nerves respectively unto either side; according to the indifferency, or original and native prepotency, there ariseth an equality in both, or prevalency on either side. And so may it be made out, what many may wonder at, why some most actively use the contrary Arm and Leg; for the vigour of the one dependeth upon the upper part of the spine, but the other upon the lower.
And therefore many things are Philosophically delivered concerning right and left, which admit of some suspension. That a Woman upon a masculine conception advanceth her right Leg, will not be found to answer strick observation. That males are conceived in the right side of the womb, females in the left, though generally delivered, and supported by ancient testimony, will make no infallible account; it happening oft times that males and females do lie upon both sides, and Hermaphrodites for ought we know on either. It is also suspitious what is delivered concerning the right and left testicle, that males are begotten from the one, and females from the other. For though the left seminal vein proceedeth from the emulgent, and is therefore conceived to carry down a serous and feminine matter; yet the seminal Arteries which send forth the active materials, are both derived from the great Artery. Beside this original of the left vein was thus contrived, to avoid the pulsation of the great Artery, over which it must have passed to attain unto the testicle. Nor can we easily infer such different effects from the divers situation of parts which have one end and office; for in the kidneys which have one office, the right is seated lower then the left, whereby it lieth free, and giveth way unto the Liver. And therefore also that way which is delivered for masculine generation, to make a strait ligature about the left testicle, thereby to intercept the evacuation of that part, deserveth consideration. For one sufficeth unto generation, as hath been observed in semicastration, and oft times in carnous ruptures. How an Horse or Bull may generate after they be gelt. Beside, the seminal ejaculation proceeds not immediately from the testicle, but from the spermatick glandules; and therefore Aristotle affirms (and reason cannot deny) that although there be nothing diffused from the testicles, an Horse or Bull may generate after castration; that is, from the stock and remainder of seminal matter, already prepared and stored up in the Prostates or grandules of generation.
Thirdly, Although we should concede a right and left in Nature, yet in this common and received account we may err from the proper acception; mistaking one side for another; calling that in Man and other animals the right which is the left, and that the left which is the right, and that in some things right and left, which is not properly either.
For first the right and left, are not defined by Phylosophers according to common acception, that is, respectively from one Man unto another, or any constant site in each; as though that should be the right in one, which upon confront or facing, stands athwart or diagonally unto the other; but were distinguished according to the activity and predominant locomotion upon either side. Thus Aristotle in his excellent Tract de incessu animalium, ascribeth six positions unto Animals, answering the three dimensions; which he determineth not by site or position unto the Heavens, but by their faculties and functions; and these are Imum summum, Ante Retro, Dextra et Sinistra: that is, the superiour part, where the aliment is received, that the lower extream, where it is last expelled; so he termeth a Man a plant inverted; for he supposeth the root of a Tree the head or upper part thereof, whereby it receiveth its aliment, although therewith it respects the Center of the Earth, but with the other the Zenith; and this position is answerable unto longitude. Those parts are anteriour and measure profundity, where the senses, especially the Eyes are placed, and those posterior which are opposite hereunto. The dextrous and sinistrous parts of the body make up the latitude; and are not certain and inalterable like the other; for that, saith he, is the right side, from whence the motion of the body beginneth, that is, the active or moving side; but that the sinister which is the weaker or more quiescent part. Of the same determination were the Platonicks and Pythagoreans before him; who conceiving the heavens an animated body, named the East, the right or dextrous part, from whence began their motion: and thus the Greeks, from whence the Latins have borrowed their appellation, have named this hand δέξια, denominating it not from the site, but office, from δέχομαι capio, that is, the hand which receiveth, or is usually implied in that action.
Now upon these grounds we are most commonly mistaken, defining that by situation which they determined by motion; and giving the term of right hand to that which doth not properly admit it. For first, Many in their Infancy are sinistrously disposed, and divers continue all their life Ἀριστεροί, that is, left handed, and have but weak and imperfect use of the right; now unto these, that hand is properly the right, and not the other esteemed so by situation. Thus may Aristotle be made out, when he affirmeth the right claw of Crabs and Lobsters is biggest, if we take the right for the most vigorous side, and not regard the relative situation: for the one is generally bigger then the other, yet not alwayes upon the same side. So may it be verified what is delivered by Scaliger in his Comment, that Palsies do oftnest happen upon the left side, if understood in this sense; the most vigorous part protecting it self, and protruding the matter upon the weaker and less resistive side. And thus the Law of Common-Weals, that cut off the right hand of Malefactors, if Philosophically executed, is impartial; otherwise the amputation not equally punisheth all.
Some are Ἀμφιδέξιοι, that is, ambidextrous or right handed on both sides; which happeneth only unto strong and Athletical bodies, whose heat and spirits are able to afford an ability unto both. Apt for contention. And therefore Hippocrates saith, that Women are not ambidextrous, that is, not so often as Men; for some are found, which indifferently make use of both. And so may Aristotle say, that only Men are ambidexterous; of this constitution was Asteropæus in Homer, and Parthenopeus the Theban Captain in Statius: and of the same, do some conceive our Father Adam to have been, as being perfectly framed, and in a constitution admitting least defect. Now in these Men the right hand is on both sides, and that is not the left which is opposite unto the right, according to common acception.
Again, Some are Ἀμφαριστεροὶ, as Galen hath expressed it; that is, ambilevous or left-handed on both sides; such as with agility and vigour have not the use of either: who are not gymnastically Strongly or fit for corporal exercise. composed: nor actively use those parts. Now in these there is no right hand: of this constitution are many Women, and some Men, who though they accustom themselves unto either hand, do dexterously make use of neither. And therefore although the Political advice of Aristotle be very good, that Men should accustom themselves to the command of either hand: yet cannot the execution or performance thereof be general: for though there be many found that can use both, yet will there divers remain that can strenuously make use of neither.
Lastly, These lateralities in Man are not only fallible, if relatively determined unto each other, but made in reference unto the heavens and quarters of the Globe: for those parts are not capable of these conditions in themselves, nor with any certainty respectively derived from us, nor from them to us again. And first in regard of their proper nature, the heavens admit not these sinister and dexter respects; there being in them no diversity or difference, but a simplicity of parts, and equiformity in motion continually succeeding each other; so that from what point soever we compute, the account will be common unto the whole circularity. And therefore though it be plausible, it is not of consequence hereto what is delivered by Solinus. That Man was therefore a Microcosm or little World, because the dimensions of his positions were answerable unto the greater. For as in the Heavens the distance of the North and Southern pole, which are esteemed the superiour and inferiour points, is equal unto the space between the East and West, accounted the dextrous and sinistrous parts thereof; so is it also in Man, for the extent of his fathome or distance betwixt the extremity of the fingers of either hand upon expansion, is equal unto the space between the sole of the foot and the crown. But this doth but petionarily infer a dextrality in the Heavens, and we may as reasonably conclude a right and left laterality in the Ark or naval edifice of Noah. For the length thereof was thirty cubits, the breadth fifty, and the height or profundity thirty; which well agreeth unto the proportion of Man, whose length, that is, a perpendicular from the vertex unto the sole of the foot is sextuple unto his breadth, or a right line drawn from the ribs of one side to another; and decuble unto his profundity; that is, a direct line between the breast bone and the spine.
Again, They receive not these conditions with any assurance or stability from our selves. For the relative foundations and points of denomination, are not fixed and certain, but variously designed according to imagination. The Philosopher accounts that East from whence the Heavens begin their motion. The Astronomer regarding the South and Meridian Sun, calls that the dextrous part of Heaven which respecteth his right hand; and that is the West. Poets respecting the West, assign the name of right unto the North, which regardeth their right hand; and so must that of Ovid be explained utque duæ dextrâ Zonæ totidemquæ sinistrâ. Declarable from the original expression, Psalm 89. 13. But Augurs or Southsayers turning their face to the East, did make the right in the South; which was also observed by the Hebrews and Chaldeans. Now if we name the quarters of Heaven respectively unto our sides, it will be no certain or invariable denomination. For if we call that the right side of Heaven which is seated Easterly unto us, when we regard the Meridian Sun; the inhabitants beyond the Æquator and Southern Tropick when they face us, regarding the Meridian, will contrarily define it; for unto them, the opposite part of Heaven will respect the left, and the Sun arise to their right.
And thus have we at large declared that although the right be most commonly used, yet hath it no regular or certain root in nature. Since it is not confirmable from other Animals: Since in Children it seems either indifferent or more favourable in the other; but more reasonable for uniformity in action, that Men accustom unto one: Since the grounds and reasons urged for it, do not sufficiently support it: Since if there be a right and stronger side in nature, yet may we mistake in its denomination; calling that the right which is the left, and the left which is the right. Since some have one right, some both, some neither. And lastly, Since these affections in Man are not only fallible in relation unto one another, but made also in reference unto the Heavens, they being not capable of these conditions in themselves, nor with any certainty from us, nor we from them again.
And therefore what admission we ow unto many conceptions concerning right and left, requireth circumspection. That is, how far we ought to rely upon the remedy in Kiranides, that is, the left eye of an Hedg-hog fried in oyl to procure sleep, and the right foot of a Frog in a Dears skin for the Gout; or that to dream of the loss of right or left tooth, presageth the death of male or female kindred, according to the doctrine of Artemidorus. What verity there is in that numeral conceit in the lateral division of Man by even and odd, ascribing the odd unto the right side, and even unto the left; and so by parity or imparity of letters in Mens names to determine misfortunes on either side of their bodies; by which account in Greek numeration, Hephæstus or Vulcan was lame in the right foot, and Anibal lost his right eye. And lastly, what substance there is in that Auspicial principle, and fundamental doctrine of Ariolation, that the left hand is ominous, and that good things do pass sinistrously upon us, because the left hand of man respected the right hand of the Gods, which handed their favours unto us.
That Men swim naturally, if not disturbed by fear; that Men being drowned and sunk, do float the ninth day when their gall breaketh; that Women drowned, swim prone, but Men supine, or upon their backs; are popular affirmations, whereto we cannot assent. And first, that Man should swim naturally, because we observe it is no lesson unto other Animals, we are not forward to conclude; for other Animals swim in the same manner as they go, and need no other way of motion for natation in the water, then for progression upon the land. And this is true whether they move per latera, that is, two legs of one side together, which is Tollutation or ambling; or per diametrum, lifting one foot before, and the cross foot behind, which is succussation or trotting; or whether per frontem or quadratum, as Scaliger terms it, upon a square base, the legs of both sides moving together, as Frogs and salient Animals, which is properly called leaping. For by these motions they are able to support and impel themselves in the water, without alteration in the stroak of their legs, or position of their bodies.
But with Man it is performed otherwise; for in regard of site he alters his natural posture and swimmeth prone; whereas he walketh erect. Again, in progression the arms move parallel to the legs, and the arms and legs unto each other; but in natation they intersect and make all sorts of angles. And lastly, in progressive motion, the arms and legs do move successively, but in natation both together; all which aptly to perform, and so as to support and advance the body, is a point of Art, and such as some in their young and docile years could never attain. But although swimming be acquired by art, yet is there somewhat more of nature in it then we observe in other habits, nor will it strictly fall under that definition; for once obtained, it is not to be removed; nor is there any who from disuse did ever yet forget it.
Secondly, That persons drowned arise and float the ninth day when their gall breaketh, is a questionable determination both in the time and cause. For the time of floating, it is uncertain according to the time of putrefaction, which shall retard or accelerate according to the subject and season of the year; for as we observed, Cats and Mice will arise unequally, and at different times, though drowned at the same. Such as are fat do commonly float soonest, for their bodies soonest ferment, and that substance approacheth nearest unto air: and this is one of Aristotles reasons why dead Eels will not float, because saith he, they have but slender bellies, and little fat.
