XIX. Achilles too, the pupil of Chiron, discovered^aAchilleos. a plant to heal wounds, which is therefore called achilleos, and by it he is said to have cured Telephus. Some have it that he was the first to find out that copper-rust is a most useful ingredient of plasters, for which reason he is represented in paintings as scraping it with his sword from his spear on to the wound of Telephus, while others hold that he used both remedies.

Some give the name sideritis to another plant, which grows on boundary walls and has a foul smell when crushed, and also to yet another, like this but with paler and more fleshy leaves, and with more tender stalks, growing in vineyards; finally to a third, two cubits high, with thin, triangular twigs, leaves like those of the fern, a long foot-stalk and seed like that of beet.
