The Metaphysics

It was only in the early 13th century, when Michael Scot translated the Arabic version contained in Averroe's Long Commentary on the Metaphysics (the so-called Metaphysica Nova), that the text became fully available in the Latin West, some time after a tradition of commentaries on the Categories had been established. Most of the early English commentaries are based on the Metaphysica Nova.

• Metaphysica Vetustissima, ascribed to James of Venice. See Aristoteles Latinus XXV. Contains only the first four books. A highly literal translation, even down to the word order. Although he sometimes translates the same Greek word with different Latin words, he systematically translates the key terms in a fixed way, sometimes deferring to Boethius's vocabulary.
• Metaphysica Vetus, probably a revision of James's translation.
• Metaphysica Media, also known as Translatio anonyma. A second translation from the Greek (the Translatio Media) seems to have been used by Albert the Great as the basis of his commentary.” See Aristoteles Latinus XXV. It contains lib. I-X, XII-XIV. The translation is anonymous, but a close relationship has been demonstrated between the Media and the Translatio Vaticana of the Physics", an anonymous translation dating back probably to the second half of the 12th century. Reading 'Canoniensis' as 'Cremononsis', Minio-Paluello tentatively ascribes it to Gerard of Cremona (d.1187), best known as a translator from Arabic into Latin. See "Latin Medieval Translations of Aristotle's Metaphysics", Marta Borgo, Amerini & Galluzzo 2013 p. 37 ff.
• Metaphysica Nova: Aristotle's text taken from the translation of Averroes' commentary, probably by Michael Scot, 1220s. The first complete translation of the Metaphysics.
