Ceolfrith was an Anglo-Saxon Benedictine abbot who led the twin monasteries of Monkwearmouth and Jarrow in Northumbria during the late 7th and early 8th centuries. A close associate of Benedict Biscop, he eventually became the sole head of both monastic sites. He is widely recognized for his mentorship of the scholar Bede, whom he supervised from childhood, and for commissioning the production of the Codex Amiatinus, a significant complete manuscript of the Vulgate Bible. He died in Langres while traveling to deliver a Bible to the Pope.
