Plutarch, Symposiacs IV.5
for as the ass is worshipped by them as the first discoverer of fountains, so perhaps the hog may be had in like veneration, which first taught them to sow and plough. Nay, some say that the Jews also abstain from hares, as abominable and unclean creatures.
They have reason for that, said Lamprias, because a hare is so like an ass which they detest; 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; except in this likewise imitating the Egyptians, they 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. Besides, they seem to excel all other creatures in quickness of hearing; whence it was that the Egyptians painted a hare’s ear amongst their other hieroglyphics, as an emblem of hearing. But the Jews do hate swine’s flesh, because all the barbarians are naturally fearful of a scab and leprosy, which they presume comes by eating such kind of flesh.
