At a later period the Athenians decreed that their coins should bear the image of this useful quadruped;[XVI-78] and though they then offered it to their gods, the ceremonies even of the sacrifice testified the repugnance felt at shedding its blood. The sacrificer fled with the greatest speed after he had struck it; he was followed, and, to avoid being arrested, he threw away the axe he had used, and accused it of causing the death of the innocent ox. The axe was then seized and tried; some one defended it, and alleged that it was less guilty than the grinder who had sharpened the blade. The latter cast the odium of the crime on the grinding stone, so that the trial was never ended, and the pretended offence remained unpunished.[XVI-79] For a long time the greater part of the ancients considered it a sin to eat the flesh of the ox, the companion of the agriculturist, whose patient vigour hollows the furrow which is to be the means of his support.[XVI-80] But the bad example of Proserpine, who prepared one for Hercules,[XVI-81] caused these scruples, one by one, to be hushed, the solemn prohibition of the legislator of Athens forgotten;[XVI-82] and, in spite of the obstinate resistance of the Pythagorians and the disciples of Empedocles, every one declared in favour of the doctrines of Zeno and Epicurus. Moreover, it is certain that the heroes of Homer were not so scrupulous: Menelaus offered roast-beef to Telemachus; Agamemnon also presented some to the wise Nestor; and an ox, roasted whole, frequently appeased the robust appetite of the illustrious chiefs of Greece.[XVI-83] If we go back to centuries still more remote, and of which a venerable historian has preserved us an account, we find herds of oxen were possessed by the great patriarchal families.[X][XVI-84] Abraham cooked a calf and served it to the three angels, in the valley of Mamre;[XVI-85] and the flesh of this animal, whether ox or heifer, was evidently much in use in the primitive ages, since no particular proscription exempts them from those beings having “life and motion,”[XVI-86] and which are to serve us as food.[XVI-87] As to Moses, far from interdicting it to the Israelites, he places the ox in the first rank of pure animals,[XVI-88] whose flesh was allowed them. The oracle of ancient medicine, Hippocrates, praises the flesh of the ox, in which he recognises the most nutritious qualities, but nevertheless he believes it to be heavy and indigestible.[XVI-89] Of what material, then, must have been the stomach of Theagenes, of Thasos--he, who devoured a whole bull in one day.[XVI-90]
