  Due to the closure of the Academy in 529 and the dominance of the Latin language in the West to the virtual exclusion of Greek, little of the ancient commentary tradition exerted any influence on the Latin Middle Ages. Thus, in spite of the many commentaries produced in the ancient world, the main texts available to authors dealing with categories after the sixth century were Boethius' translation of and Commentary on Aristotle's Categories, the Categoriae decem (a Themistian paraphrase of Aristotle's Categories traditionally attributed to St. Augustine), and a composite translation which included the lemmata of Boethius' Commentary and some glosses. A few other works refer to categories, such as Porphyry's Isagoge, translated and commented on twice by Boethius, and Boethius' two Commentaries on On Interpretation and his treatise On the Trinity. However, the growing interest in logic that began in the ninth century and then was revived in the eleventh century made Boethius' translation and Commentary on the Categories the center of attention on this topic.
