Gottesfreunde
The group achieved a nascent institutional form in 1367 when wealthy layman Rulman Merswin purchased and restored a derelict monastery in Strasbourg known as the "grünenwörth" ('Green Isle'). Grünenwörth served as a refuge for study for the Friends of God and as a “school of prophets” which produced a number of mystical texts. Merswin is suspected of being the anonymous author The Friend of God from the Oberland.
