Petrus de Dacia (Swedish monk)

Petrus de Dacia (Latin: Peter from Denmark) was a Swedish monk of the Dominican order who lived in Gotland from the 1230s to 1289. Though he wrote in Latin, he is often credited as the first author in Sweden.

Petrus de Dacia is famous for his correspondence with and his 15 visits to Christina von Stommeln, a Beguine, the first woman to have reportedly received stigmata (source: Codex Iuliacensis, ca. 1320–1350). Christina lived around Stommeln near Cologne; Stommeln was part of the County of Jülich of the Holy Roman Empire, where her relics are venerated.
