Henry Suso, OP (also called Amandus, a name adopted in his writings, and Heinrich Seuse or Heinrich von Berg in German; 21 March 1295 – 25 January 1366) was a German Dominican friar and the most popular vernacular writer of the fourteenth century (when considering the number of surviving manuscripts).

From this point forward in his account of his spiritual life, a burning love for Eternal Wisdom dominated his thoughts and controlled his actions; his spiritual journey culminated in a mystical marriage to Christ in the form of the Eternal Wisdom,[3] an allegorical Goddess in the Hebrew Bible associated with Christ in medieval devotion.

[6] It is also known that he had various devoted disciples, a group including both men and women, especially those connected to the Friends of God movement.

His influence was especially strong in many religious communities of women, particularly in the Dominican Monastery of St. Katharinental in the Thurgau, a famous nursery of mysticism in the 13th and 14th centuries.

She translated some of his Latin writings into German, collected and preserved most of his extant letters, and at some point began gathering the materials that Suso eventually put together into his Life of the Servant.

Early in his life, Suso subjected himself to extreme forms of mortifications; later on he reported that God told him they were no longer necessary.

At some point between 1334 and 1337 Suso translated this work into Latin, but in doing so added considerably to its contents, and made of it an almost entirely new book, which he called the Horologium Sapientiae (Clock of Wisdom).

[13] The mutual love of God and man which is his principal theme gives warmth and color to his style.

He used the full and flexible Alemannic idiom with rare skill, and contributed much to the formation of good German prose, especially by giving new shades of meaning to words employed to describe inner sensations.

[14] In the world Suso was esteemed as a preacher, and was heard in the cities and towns of Swabia, Switzerland, Alsace, and the Netherlands.

Suso was reported to have established among the Friends of God a society which he called the Brotherhood of the Eternal Wisdom.

The so-called Rule of the Brotherhood of the Eternal Wisdom is but a free translation of a chapter of his Horologium Sapientiae and did not make its appearance until the fifteenth century.

Suso was beatified in 1831 by Pope Gregory XVI, who assigned 2 March as his feast day, celebrated within the Dominican Order.
