In his chapter on anthropology and human physiology in the encyclopedic "Natural History", Pliny notes that "there are even those who are born of both sexes, whom we call hermaphrodites, at one time "androgyni"" ("andr-", "man", and "gyn-", "woman", from the Greek). The Sicilian historian Diodorus (1st century BC) wrote that "there are some who declare that the coming into being of creatures of a kind such as these are marvels "(terata)", and being born rarely, they announce the future, sometimes for evil and sometimes for good". Isidore of Seville ("c." 560–636) described a hermaphrodite fancifully as those who "have the right breast of a man and the left of a woman, and after coitus in turn can both sire and bear children".
