David of Augsburg
David Of Augsburg, a Franciscan of the 13th century, was a friend of Berthold of Ratisbon, whom he accompanied on his missionary journeys. He died in Augsburg in 1271. Three tractates of his are given in the Bibliotheca Patrum, vol. 13, viz. The Novices' Formula for the Reformation of the outer Man, A Formula for the inner Man, and A Mirror of the seven Steps of a Religious. These tracts have been erroneously ascribed to Bonaventura. Several of his works were written in the German language, and of this class six have been published by Pfeiffer in his Deutsche Mystiker des Men Jahrhuunderts (Leipzig, 1845). — Oudin, Comment. de Script.
