About This Book

The work assembles systematic observations on animals, insects, and trees, combining natural history with practical notes. It surveys insect forms and habits, including bees, silk‑producing worms, spiders, and parasitic species, and discusses reproduction, classification, diseases, and useful products like honey and silk. It then examines animal anatomy in detail, limb by limb and organ by organ, comparing organs, vital functions, and bodily peculiarities across species. Later sections catalogue trees and exotic plants, describing aromatic gums, spices, frankincense, myrrh, and methods for producing and testing unguents and perfumes, and noting their uses and regions of origin.

CHAP. 60. (27.)—OMPHACIUM.

Omphacium604 is also a kind of oil, which is obtained from two trees, the olive and the vine, by two different methods. It is produced from the former by pressing the olive while it is still in the white state. That is of an inferior quality which is made from the druppa—such being the name that is given to the olive before it is ripe and fit for food, but already beginning to change its colour. The difference between them is, that the latter kind is green, the former white. The omphacium that is made from the vine is extracted from either the psythian605 or the Aminean grape, when the grapes are about the size of a chick-pea, just before the rising of the Dog-star. The grape is gathered when the first bloom is appearing upon it, and the verjuice is extracted, after which the residue606 is left to dry in the sun, due precautions being taken against the dews of the night. The verjuice, after being collected, is put into earthen vessels, and then, after that, stored in jars of Cyprian copper.607 The best kind is that which is of a reddish colour, acrid, and dry to the taste. The price at which it sells is six denarii per pound. Omphacium is also made another way—the unripe grape is pounded in a mortar, after which it is dried in the sun, and then divided into lozenges.
