The Dominican Heinrich Seuse, blessed (around 1295-1366), was a student of Meister Eckhart and is mentioned alongside him and Johannes Tauler as one of the most significant representatives of so-called German mysticism. His 'Horologium Sapientiae' is among the most read and widespread religious books of the 14th and 15th centuries. This work was based on the 'Büchlein der ewigen Weisheit,' which was also written by Seuse in Middle High German. While the German original could address an uneducated audience, Seuse aimed for a different target audience (primarily his fellow monks) with the Latin book and adapted it accordingly. The book is presented in dialogue form, with Eternal Wisdom (Jesus Christ) instructing a disciple in contemplation of the Passion and a devotion that fosters spiritual progress, sometimes appearing in a male form and at other times in a female form.
