Boniface of Mainz
c. 675 AD — June 5, 754 AD
Boniface of Mainz, born Wynfrith around 675 in Crediton, Devon, organized the Church across pagan Germanic lands and most famously felled Donar's Oak at Geismar, building a chapel from its timbers. At nearly eighty, he returned to Frisia for a final mission and was martyred near Dokkum on June 5, 754, holding a Gospel book pierced by a sword.
