Cuthbert's letter also relates a five-line poem in the vernacular that Bede composed on his deathbed, known as "Bede's Death Song". It is the most-widely copied Old English poem and appears in 45 manuscripts, but its attribution to Bede is not certain—not all manuscripts name Bede as the author, and the ones that do are of later origin than those that do not. Bede's remains may have been transferred to Durham Cathedral in the 11th century; his tomb there was looted in 1541, but the contents were probably re-interred in the Galilee chapel at the cathedral.
