The poison-habit, as we might call the craving for the stimulus of unnatural diet, is the oldest vice, and in some of its forms has been practiced by almost every nation known to history or tradition. Thousands of years before Lot got drunk on home-made wine, the ancestors of the Brahmans fuddled with soma-juice; Zoroaster enacts laws against habitual intoxication; the art of turning grape-juice from a blessing into a curse seems to have been known to the nations of Iran, to the Parsees, and to the first agricultural colonists of the lower Nile. Nunus, the Arabian Noah, is said to have planted vineyards on the banks of the Orontes; the worship of Bacchus was introduced into Asia Minor several centuries before the birth of Homer. The origin of the opium habit antedates the earliest records of Chinese history; for immemorial ages the Tartars have been addicted to the use of Koumis (fermented mare’s milk), the Germanic nations to beer, the natives of Siam to tea and sago-wine. Intoxication and the excessive use of animal food were prevalent vices, especially in the larger cities, of pagan Greece and Rome. Yet the ancients sinned with their eyes half open. Their recognition of dietetic abuses was expressed in the word frugality, which literally meant subsistence on tree fruits—or, at least, vegetable products—in distinction from the habitual use of flesh-food. The advantages of temperate habits were never directly denied; the law of Pythagoras enjoins total abstinence from wine and flesh, and the name of a “Pythagorean” became almost a synonym of “philosopher.” In all but the most depraved centuries of Imperial Rome, wine was forbidden to children and women. The festival of the Bona Dea commemorated the fate of a Roman matron who had yielded to the temptation of intoxicating drink, and was slain by the hand of her stern husband. Lycurgus recommends the plan of letting the pupils of the military training-schools witness the bestial conduct of a drunken Helot, in order to inspire them with an abhorrence of intoxication. The bias of public opinion always respected the emulation of patriarchal frugality and frowned upon the excesses of licentious patricians.
