Opicinus de Canistris (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.
The “pictures” are a complex series of maps and schematic diagrams in two manuscripts currently held at the Vatican library, Palatinus 1993 and Vaticanus 6435. These drawings were a means for Opicinus to chart the spiritual realities that he believed were the underpinnings of the physical world.
