Quaestiones Convivales

But after we began to enquire after the cause of this disease, the first thing that puzzled us was to find out the reason why bulimy seizes upon those that travel in the snow. As Brutus, one time marching from Dyrrachium to Apollonia in a deep snow, was endangered of his life by bulimy, whilst none of those that carried the provisions for the army followed him; just when the man was ready to faint and die, some of his soldiers were forced to run to the walls of the enemies’ city, and beg a piece of bread of the sentinels, by the eating of which he was presently refreshed; for which cause, after Brutus had made himself master of the city, he treated all the inhabitants very mercifully. Asses and horses are frequently troubled with bulimy, especially when they are loaden with dry figs and apples; and, which is yet more strange, of all things that are eaten, bread chiefly refreshes not only men but beasts; so that, by taking a little quantity of bread, they regain their strength and go forward on their journey.

After all were silent, I (who had observed that dull fellows and those of a less piercing judgment were satisfied with and did acquiesce in the reasons the ancients gave for bulimy, but to men of ingenuity and industry they only pointed out the way to a more clear discovery of the truth of the business) mentioned Aristotle’s opinion, who says, that extreme cold without causes extreme heat and consumption

At length says Soclarus: I like the beginning of this reason very well, for the bodies of travellers in a great snow must of necessity be surrounded and condensed with cold; but that from the heat within there should arise such a consumption as invades the principle of respiration, I can no way imagine. I rather think, says he, that abundance of heat penned up in the body consumes the nourishment, and that failing, the fire as it were goes out. Here it comes to pass, that men troubled with this bulimy, when they are ready to starve with hunger, if they eat never so little meat, are presently refreshed. The reason is, because meat digested is like fuel for the heat to feed upon.
