Works

Though traditionally Versor has often been considered a Thomist, more recent studies show his dependence on both Thomas Aquinas and Albert the Great, and evidence suggests that, by his contemporaries, Versor was regarded as an authority of his own.^[5] Insofar as he can be regarded as a Thomist, his position represents an interesting, pre-Cajetan version of Thomism.^[6] His commentaries covered most of the works of Aristotle, and his textbooks were very widely circulated in the period 1470 to 1520.^[7]

A large part of his questions on Aristotle and Aquinas was translated into Hebrew by Eli Habillo, during the 1470s.^[8] Questions on Aristotle were printed in a number of editions at Cologne, from 1485 onwards.^[9]
