Raoul Le Sauvage, Silvestris, Dominican, was licentiate in theology in 1429 and master in November, 1431. He appears to have had a great reputation as a preacher at Rouen where he preached many sermons between 1427 and 1447

Jean Marcel, in the Procès de Réhabilitation, refers to him as Jean but in the Trial Record he is named Raoul in every instance (except in the session of April 12) with the title of bachelor of theology and once as master.

A Radulphus Silvestris, priest of the diocese of Rouen, was described in 1403 as having been a master of arts for fifteen years, a bachelor of law, and student in theology at the same time as Erard Emengart, Guillaume de Baudribosc, André Marguerie, Jean Garin and Guillaume Desjardins.
