 Ibn Rushd’s work deploys various methods and styles. Many treatises are in the form of a commentary, most famously and extensively on Aristotle—covering nearly the whole Aristotelian corpus—but also on Galen’s medical treatises, as well as on other philosophers such as Plato, Ibn Sīnā and Ibn Bājja. Many other treatises, devoted to specific issues, are not in commentary form. (For a detailed inventory of texts and translations see §10.1.)
