Davmar was the great Thaumaturge working in the early years of the reign of King Mumberthrax Flathead, who discovered that the power of magic spells could be stored on paper by storing Incantation on special Presence-imbued paper, eventually led to the widespread use of magic.
Davmar was also known for spending six years of his life as a zucchini farmer, despite the fact that he was allergic to zucchinis, and could not eat them himself. (Flathead Calendar)
