Abstract

The present article locates for the first time the four medieval Greek-Latin translations of the Aristotelian Metaphysics in the Greek manuscript tradition, based on representative collations. Two of the translations, the Translatio Guillelmi of Wilhelm of Moerbeke, cited up to now in the text editions (Ross, Jaeger), and the Translatio Composita, can be neglected in a new edition of the Metaphysics. On the other hand, the Translatio Iacobi and the Translatio anonyma must be consulted for the constitution of the text: the latter actually turns out to be the oldest accessible witness to the meagerly transmitted _β_ -branch.
