After his death Arthur’s soul went into a raven’s body in Cornish folklore.
The raven seems to have been associated with the god, Bran, whose name signifies a raven in both Welsh and Irish. Beliefs concerning the ravens at the Tower of London, whose departure is thought to herald Britain’s downfall, may be a vestige of the cult of Bran.
Arthur’s soul was also credited with having entered the form of a chough and a puffin. Some think that the raven was a later replacement for the chough when the species became extinct within the county.
