 Avempace wrote commentaries on many of them, beginning with his annotations on the Chapters, or Sections, and on the Eisagoge, mixed with ones on the Categories. His annotations are preserved in two manuscripts: Oxford Pococke 206 and, to a larger extent, Escorial Derenbourg 612. These annotations on the books belonging to the introductory genre are often intermingled and may offer different versions (‛Alawi 1983: 80–83). We are changing the order of the Escorial manuscript and analyzing Avempace’s annotations on the Five Sections before those on the Eisagoge as they are adressed to one who intends to learn logic, and the sciences, in general.
