ابن زهر
Kitab al-Taysir seems to be the last book of Ibn Zuhr before his death. As mentioned in the introduction, the book was authored at the request of his friend, Averroes, to act as a compendium to his medical encyclopedia Colliget which focused more on general topics of medicine. The two books were later translated into Hebrew and Latin, where they used to be printed as a single book and remained popular as late as the 18th century.
