This manuscript, of French origin, came to the Carthusian Monastery of Basel after having been the property of Johannes Heynlin. The massive volume contains Aristotle's six works on logic, some with commentary, which were assembled into the so-called “Organon“ only after the time of Aristotle. The decoration and science are complementary: each of the books of the main text begins with an elaborate ornamental initial; the commentary, if there is one, is grouped closely around the main text and is mostly unadorned.

This manuscript contains an anonymous Hebrew paraphrase of the first five books of Averroes' (Abu al Walid Muhammed Ibn Rushd, c.1126-1198) Commentaire Moyen (middle commentary) on the Organon attributed to Aristotle. From the 13th century on, Hebrew paraphrases and compilations of certain books of the Organon were written by intellectual Jews from Provence, such as Jacob Anatolio Abba Mari (ca. 1194-1256); more than fifty manuscripts of this work of his have survived. The anonymous paraphrase found in the Bibliothèque de Genève's Ms. heb.12 is part of the same series. (iss)

This miscellany of Aristotelian logic and dialectics (AL 1160) was produced as a single work and written by various hands in textualis. It was then commented in the margins by various hands, sometimes with multiple hands in the same comment. The first part comprises the Isagoge by Porphyry (pp. 1-17), Aristotle's Categoriae (pp. 17-46) and De interpretatione (pp. 46-63) in the translation of Anicius Manlius Severinus Boethius, the anonymous twelfth-century Aristotelian compilation Liber sex principiorum (pp. 63-78) and Boethius' own De divisione (pp. 78-96). The second part begins with Boethius' De differentiis topicis (pp. 97-148). The third part contains Boethius' translation of Aristotle's Topica (pp. 149-287). This is followed by Boethius' translation of Aristotle's De sophisticis elenchis (pp. 288-322). The fourth part begins with Boethius' translation of Aristotle's Analytica priora (pp. 323-392). The remainder of p. 392 is ruled but otherwise empty. Page 393 is completely blank. Page 394 was used for notes. The fifth part contains the Latin translation of Aristotle's Analytica posteriora (pp. 395-434). The volume has a green (or blue) cover decorated with large rhombi (ink or scudding decoration). The endband is finished in a natural shade of blue. The volume originally had two eyelet fastenings with simple holes stamped through the bottom board. There are multiple names noted on the top pastedown: dasz buch ist [getilgt] wirt oder sinez bruoder [sic] […] Rug Hanns […] Jacob Wirt von Sant Gallen […] Maister Cuonrat […]. Page 41 is stamped with the 1553-1564 St. Gallen library stamp of Abbot Diethelm Blarer. Numerous details have been added: manicules (p. 36, 93, 276, 302, 352, 416, 432 und 434), topical diagrams (p. 132), a tournament scene (p. 241), a banderole with the year ·1·5·6·7· written on it (p. 244, 245), nudes  (p. 254, 432, rear pastedown), vignettes (p. 300), a secant (p. 350), Aristotelian categories (p. 354, 366) as well as crowns (rear pastedown).

The main content of the codex consists of commentaries by Boethius on Cicero's Topica and on the Isagoge by the neoplatonic philosopher Porphyrius († after 300), Porphyrius's Isagoge itself and assorted other texts. Among these are, for example, small pieces by Walahfried Strabo (Regulae metricae; a letter with the incipit Domino meo benedictus salus et vita) and by Marius Victorinus, a 4th century Roman scholar (De generatione divina).
