David of Augsburg

David of Augsburg (early 13th century – 19 November 1272) was a medieval German mystic, and a Franciscan friar.

His major work, written in the 1240s, is entitled The Composition of the Interior and Exterior Man according to the Triple states of Beginners, Proficient, and Perfect.

It was popular, since close to 400 manuscripts of the whole or parts survive, along with numerous translations.

He also composed various vernacular texts in Middle High German (24 are known, though at times doubt has been cast on the veracity of the attribution).
