 The tradition credits Marius Victorinus (fourth century CE) with a translation of the Categories, the De Interpretatione, and Porphyry’s Isagoge (Cassiodorus, Instit. II, 3, 18). The same tradition credits him with a commentary in eight books on the Categories. A few years later Vettius Agorius Praetextatus is known to have translated the Greek paraphrases of the Prior and Posterior Analytics produced by Themistius (Boethius, De Int.2 3.6–4.3). None of these works have reached us, with the exception of excerpts from Victorinus’ translation of the Isagoge. An anonymous paraphrase of the Categories falsely attributed to Augustine and traditionally known as Categoriae Decem has survived only because it was widely read and used in the early Middle Ages. Finally, an incomplete paraphrase of the Categories is preserved in Martianus Capella’s On Dialectic (the forth book of his The Marriage of Philosophy and Mercury, an influential textbook on the seven liberal arts dating from the fifth century CE). Even these few remarks suffice to document a sustained effort to provide the students with a Latin Organon that reflected the teaching needs of the time.
