Colliget

The Colliget is a medical encyclopedia written by the Andalusian polymath Averroes. Its original Arabic title, Kulliyat, can be rendered roughly as 'generalities', and it stands in contrast to The Specificities of Medicine, the work of his friend Ibn Zuhr. The two authors collaborated, intending their books to complement each other: one treats the general principles of medicine, the other its particular aspects.

Written between 1153 and 1169, the work was later translated into Medieval Hebrew and Latin. In Europe it became a widely used textbook, remaining in circulation until the eighteenth century.
