Knowledge of Suso's activities in subsequent years is somewhat sketchy. It is known that he served as prior of the Constance convent – most likely between 1330 and 1334, though possibly in the 1340s. 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 Argau, a famous nursery of mysticism in the 13th and 14th centuries. In the mid-1330s, during his visits to various communities of Dominican nuns and Beguines, Suso became acquainted with Elsbeth Stagel, prioress of the monastery of Dominican nuns in Töss. The two became close friends. 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".
