Moses Maimonides' On Coitus was composed at the request of an unknown high-ranking official who asked for a regimen that would be easy to adhere to, and that would increase his sexual potency, as he had a large number of slave girls. It is safe to assume that it was popular in Jewish and non-Jewish circles, as it survives in several manuscripts, both in Arabic and Judaeo-Arabic. The present edition by Gerrit Bos contains the original Arabic text, three medieval Hebrew translations, two Latin versions from the same translation (edited by Charles Burnett), and a Slavonic translation (edited by Will Ryan and Moshe Taube).
Maimonides, On the Elucidation of Some Symptoms and the Response to Them (Formerly Known as On the Causes of Symptoms)
A New Parallel Arabic-English Edition and Translation, with Critical Editions of the Medieval Hebrew Translations
The present consilium, commonly known as De causis accidentium, after the Latin translation by John de Capua, was, like the earlier consilium On the Regimen of Health, composed by Maimonides at the request of al-Malik al-Afḍal Nūr al-Dīn Alī, Saladin’s eldest son. As a result of not adopting the lifestyle and dietary recommendations in On the Regimen of Health, al-Afḍal may have continued to suffer from a number of afflictions, amongst them hemorrhoids, depression, constipation, and, possibly, a heart condition. The consilium was written after 1200, the year in which al-Afḍal was deposed and banished from Egypt permanently, but probably not long before 1204, the year in which Maimonides died.
A New Parallel Arabic-English Translation
Maimonides’ On the Regimen of Health was composed at an unknown date at the request of al-Malik al-Afḍal Nūr al-Dīn Alī, Saladin’s eldest son who complained of constipation, indigestion, and depression. The treatise must have enjoyed great popularity in Jewish circles, as it was translated three times into Hebrew as far as we know; by Moses ben Samuel ibn Tibbon in the year 1244, by an anonymous translator, and by Zeraḥyah ben Isaac ben She’altiel Ḥen who was active as a translator in Rome between 1277 and 1291. The present edition by Gerrit Bos contains the original Arabic text, the medieval Hebrew translations and the Latin translations, the latter edited by Michael McVaugh.
