The Commentary of Conrad of Prussia on the De Ente et Essentia of St. Thomas Aquinas

1. THE MAN CONRAD OF PRUSSIA Conrad of Prussia is not so much as mentioned in any of the usual sources. And even such notable mediaevalists as Mlle. Marie-Therese dAlverny Conservateur en-chef and J. Reginald ODonnell C. S. B. of the Pontifical Institute of Mediaeval Studies Toronto Canada have been unable to identify him. Nothing at all therefore is known about Conrad if that is the authors name. For there is some doubt that it is. In the colophon of the Admont commentary on Aquinas De Ente et Essentia ! we find a word so completely erased that it is illegible followed by the words de Prusya. Martin Grabmann argues that it is correct to feel that the erasure is an erasure of the name Conradi since in the colophon of the Admont commentary on Dominicus Gundissalinus De Unitate et Uno2 which follows the commentary on the De Ente et Essentia we find again an erased word followed by the words de Prusya. But the erasure is not complete. One can here read the name Conradi. 3 And so the manuscript of the commentary on the De Unitate et Uno clearly attributed this work to Conrad of Prussia before the attempted erasure.
