Of the more than sixty treatises attributed to Hippocrates, the ones that were most popular, and most commonly translated into Arabic and Latin in the Middles Ages, were the Aphorisms and the Prognostics, followed by On Regimen in Acute Diseases; the Epidemics; On the Nature of Man; On Airs, Waters, and Places; and the Oath. Contrary to the case of the works of Galen, there was never an attempt to translate the entire Hippocratic corpus into Arabic or Latin. Consequently, when printing was introduced in the second half of the fifteenth century, only these works, along with some apocryphal treatises, were published at that time.
