De Medicina

10 There are also observances necessary for a healthy man to employ during a pestilence, although in spite of them he cannot be secure. At such a time, then, he will do well to go abroad, take a voyage; when this cannot be, to be carried in a litter, walk in the open before the heat of the day, gently, and to be anointed in like manner; further as stated above he should avoid fatigue, indigestion, cold, heat, venery, and keep all the more to rule, should he feel any bodily oppression. At such a time he should not get up early in the morning nor walk about barefoot, and least so after a meal or bath. Neither on an empty stomach nor after a meal should he provoke a vomit, or set up a motion; indeed if the bowels tend to be loose, they are to be restrained. The fuller his habit of body, the more abstinence; he should avoid the bath, sweating, a midday siesta, and in any case if food has been taken previously; at such times, however, it is better then to take only one meal a day, and that a moderate one, lest indigestion be provoked. He should drink, one day water, the next day wine; if he observes these rules, there should be the least possible alteration as to the rest of his accustomed dietary. Such then are the things

to be done in pestilence of all sorts, and particularly in one brought by south winds. And the same precautions are needed by those who travel, when they have left home during an unhealthy season, or when entering an unhealthy district. Even when something prevents observance of other rules, yet he ought to keep up the alteration, mentioned above, from wine to water, and from water to wine.
