At the age of seven, Bede was sent as a "puer oblatus" to the monastery of Monkwearmouth by his family to be educated by Benedict Biscop and later by Ceolfrith. Bede does not say whether it was already intended at that point that he would be a monk. It was fairly common in Ireland at this time for young boys, particularly those of noble birth, to be fostered out as an oblate; the practice was also likely to have been common among the Germanic peoples in England. Monkwearmouth's sister monastery at Jarrow was founded by Ceolfrith in 682, and Bede probably transferred to Jarrow with Ceolfrith that year. The dedication stone for the church has survived to the present day; it is dated 23 April 685, and as Bede would have been required to assist with menial tasks in his day-to-day life it is possible that he helped in building the original church. In 686, plague broke out at Jarrow. The "Life of Ceolfrith", written in about 710, records that only two surviving monks were capable of singing the full offices; one was Ceolfrith and the other a young boy, who according to the anonymous writer had been taught by Ceolfrith. The two managed to do the entire service of the liturgy until others could be trained. The young boy was almost certainly Bede, who would have been about 14.
