That Homer came into Egypt, amongst other arguments they endeavor to prove it especially by the potion Helen gave Telemachus--in the story of Menelaus--to cause him to forget all his sorrows past, for the poet seems to have made an exact experiment of the potion Nepenthes, which he says Helen received from Polymnestes, the wife of Thonus, and brought it from Thebes in Egypt; and indeed in that city, even at this day, the women use this medicine with good success, and they say that in ancient times the medicine for the cure of anger and sorrow was only to be found among the Diospolitans, Thebes and Diospolis being affirmed by them to be one and the same city.--Diodorus Siculus, Vol. I, Chap. VII.
