Opicinus de Canistris

Opicinus de Canistris (24 December 1296 – c. 1353), also known as the ''Anonymous Ticinensis'', was an Italian priest, writer, mystic, and cartographer who generated a number of unusual writings and fantastic cosmological diagrams. Autobiographical in origin, they provide the majority of information about his life. When his works were rediscovered in the early twentieth century, some scholars deemed his works to be “psychotic” due to their extraordinary theological musings and schematic diagrams. The merits of this psychoanalytic interpretation, however, are currently under debate. Provided by Wikipedia
