Hippolytus of Rome, The Refutation of All Heresies IV.6: Zodiacal Influence; Origin of Sidereal Names

But since also they frame an account concerning the action of the zodiacal signs, to which they say the creatures that are procreated are assimilated, neither shall we omit this: as, for instance, that one born in Leo will be brave; and that one born in Virgo will have long straight hair, be of a fair complexion, childless, modest. These statements, however, and others similar to them, are rather deserving of laughter than serious consideration. For, according to them, it is possible for no Æthiopian to be born in Virgo; otherwise he would allow that such a one is white, with long straight hair and the rest. But I am rather of opinion, that the ancients imposed the names of received animals upon certain specified stars, for the purpose of knowing them better, not from any similarity of nature; for what have the seven stars, distant one from another, in common with a bear, or the five stars with the head of a dragon?—in regard of which Aratus says:—

“But two his temples, and two his eyes, and one beneath

Reaches the end of the huge monster’s jaw.”
