That the energies of our intellectual faculties are under the influence of our food, is a fact long since observed. The stupidity of the athletae, who lived upon coarse bread (coliphium) and underdone meat, was proverbial; even Hercules laboured under the imputation of a mind somewhat obtuse. Our genius, our energies are all affected by our mode of living. The rule of _Sanis omnia sana_, of Celsus, is applicable to very few individuals; and all our faculties may be rendered more keen or less vivid by temperance or excesses. As the nature of our _ingesta_ influences the functions of our digestive organs, so do these organs in their turn influence our moral powers when our physical energies are elevated or depressed. Our courage, our strength of mind, our religious and our moral train of thinking, are under the control of diet. Fasting has ever been considered as predisposing to meditation and ascetic contemplation. Tertullian tells us, that we should approach the altars fasting, or having eaten nothing but dry substances. All the religious ceremonies of the Egyptians were preceded by abstinence, and their sacrificators were allowed neither animal food nor wine. Indeed, the Egyptian priesthood were remarkable for their abstinence and self-denial, fearful, according to Plutarch, that "the body should not sit light upon the soul." Similar precautions were observed with animals, and the ox apis was not allowed to drink the waters of the Nile, as they were considered of a gross and fattening nature; even upon festive days they observed a similar moderation. It was customary, on the 9th day of the month Thoth, for every one to eat fried fish at their doors--the priests only conformed to the custom by burning theirs at the appointed time. In general they abstained from most sorts of pulse, especially beans and lentils, onions, garlic, leeks, mutton, pork; and on certain days of purification, even salt was forbidden. Many of their fasts lasted from seven to forty-two days, during which time they abstained entirely from animal food, from herbs and vegetables, and the indulgence of any passion. Similar privations were observed by all those who attended the mysteries of Juno and Ceres. In Holy Writ we find that it was after abstinence that Divine inspiration illumined the elect. The angel appeared unto Daniel after he had been three weeks without tasting flesh, or wine, or "pleasant bread." In the Acts, x., we find that the vision appeared to Peter, "when he had become hungry and would have eaten." Moses fasted forty days on Mount Sinai. We find in Jonah, that even cattle were frequently subject to this mortification, when he proclaimed in Nineveh that neither man nor beast, herd nor flock, should taste any thing; "let them not feed nor drink water." Congius Ripensis tells us, that the same restriction was imposed by the Lacedaemonians on their Helots and all domestic animals. Fasting was considered by the early Christians as an essential rite.
