Dissen, HEINRICH VON, b. October 18, 1415, at Osnabruck, in Westphalia; d. at Cologne, November 26, 1484. After studying philosophy and theology at Cologne under Heinrich von Gorinchem (Gorkum), a celebrated divine of that time and vice-chancellor of the university, he became a monk in the Carthusian monastery of the same place, and took his solemn vows January 14, 1437. He remained there all his life, which was a very laborious one, for he read much, copied many books for the library of his monastery, and composed a good many works. He was appointed sub-prior March 23, 1457, and continued in that office until his death. His literary productions, all in Latin, comprise commentaries on the Psalms, on the Apocalypse, on the Gospels of Sundays and Festivals, on the Creed of St. Athanasius, on the Lord’s Prayer, and a great number of sermons and homilies, treatises, and devotional writings, such as “De Sacerdotii dignitate”, “De multiplici bonorum verecundia”, “Quo pacto haereticorum fraudes deprehendi queant”, “Expositio in totum Missale”, “Expositio Antiphonarii”, “Consolationes in Cantica Canticorum”, “De XIII mansionibus”, etc. It does not appear that any of these works have ever been printed.
