The several parts of a now-dismembered late-13th century Organon, owned and quite creatively annotated by John Chortasmenos, are presented and studied. The main copyist of this manuscript is also identified in a number of other manuscripts of philosophical contents. Chortasmenos' exegetical practice is also discussed, with special emphasis on his sources and on his extensive use of diagrams.
