 He assembled, and carefully annotated, a surviving collection of Eckhart's Latin works.As Eckhart was the only medieval theologian tried before the Inquisition as a heretic, the subsequent (1329) condemnation of excerpts from his works cast a shadow over his reputation for some, but followers of Eckhart in the lay group Friends of God existed in communities across the region and carried on his ideas under the leadership of such priests as John Tauler and Henry Suso.Eckhart is considered by some to have been the inspirational "layman" referred to in Johannes Tauler's and Rulman Merswin's later writings in Strasbourg where he is known to have spent time (although it is doubtful that he authored the simplistic "Book of the Nine Rocks" published by Merswin and attributed to the layman knight from the north).
