Merlin.
Prince of Enchanters; also the name of a romance. He was the son of a damsel seduced by a fiend, but Blaise baptised the infant, and so rescued it from the power of Satan. He died spell-bound by his mistress Vivian in a hawthorn-bush. (See Spensers Faërie Queene, Tennysons Idylls of the King, and Elliss Specimens of Early English Metrical Romances.)
