What kind of stone memnonia3359 is, we do not find mentioned. Medea3360 is a black stone, said to have been discovered by the Medea3361 of fable: it has veins of a golden lustre, and yields a liquid like saffron in colour and with a vinous flavour. Meconitis3362 strongly resembles poppies. Mithrax3363 comes from Persia and the mountains of the Red Sea: it is of numerous colours, and reflects various tints when exposed to the sun.3364 Morochthos3365 is a stone of a leek-green colour, from which a milk exudes. Mormorion3366 is a transparent stone from India, of a deep black colour, and known also as “promnion.” When it has a mixture of the colour3367 of carbunculus, it is from Alexandria; and when it shares that of sarda,3368 it is a native of Cyprus. It is found also at Tyrus and in Galatia; and, according to Xenocrates, it has been discovered at the foot of the Alps. These stones are well adapted for cutting in relief.3369 Murrhitis3370 has just the colour of myrrh, and very little of the appearance of a gem: it has the odour also of an unguent, and smells like nard when rubbed. Myrmecias3371 is black, and has excrescences upon it like warts. Myrsinitis3372 has a colour like that of honey, and the smell of myrtle. “Mesoleucos”3373 is the name given to a stone when a white line runs through the middle; and when a black vein intersects any other colour, it is called “mesomelas.”3374
