  Although Boethius reports a translation of Themistius's paraphrase of the Posterior Analytics into Latin, and may have done a translation himself, neither of these works survived into the Middle Ages. The Latins first became acquainted with the work through the translation of James of Venice between 1125 and 1150. John of Salisbury benefits from James in his Metalogicon, giving a list of points from the work there (Book IV 6-8). The James translation became the vulgate, and the translation done for Thomas Aquinas by William Moerbeke never received much usage. Translations of Themistius's paraphrase of the work, and a lost work by al-Farabi on demonstration (or perhaps Averroes's critical remarks on that work), were used by Albert the Great, and though they dropped out of circulation soon thereafter, scholars sometimes cribbed from Albert's commentary. The commentary of Alexander of Aphrodisias (or the commentary of Philoponus, which is close to Alexander) was translated by James of Venice. This translation also quickly dropped out of circulation, but much of its content survived in marginal glosses. The Middle Commentary of Averroes was translated by William of Luna around 1300, but was not used before the latter half of the fifteenth century, though Albert the Great seems to have some knowledge of Averroes, and so his doctrines were not without influence.
