Plutarch Quaestiones Convivales 4.5.3

[3] They have reason for that, said Lamprias, because a hare is so like an ass which they detest; ¹ for in its color, ears, and the sparkling of its eyes, it is so like an ass, that I do not know any little creature that represents a great one so much as a hare doth an ass; unless in this likewise they imitate the Egyptians, and suppose that there is something of divinity in the swiftness of this creature, as also in its quickness of sense; for the eyes of hares are so unwearied that they sleep with them open.

And if it be lawful to intermix our discourse with fables, it is said that Adonis was slain by a boar. Now Adonis is supposed to be the same with Bacchus; and there are a great many rites in both their sacrifices which confirm this opinion. Others will have Adonis to be Bacchus’s paramour; and Phanocles an amorous love-poet writes thus,
