[5] jǫfurr ‘the leader’: There is nothing in DGB to justify reference to Merlin as jǫfurr, a heiti whose attestations relate specifically to leaders and rulers (LP: jǫfurr), but possibly the use of this heiti reflects influence from Geoffrey’s later Vita Merlini, which narrates the life of Merlin Caledonius (also known as Silvestris) (Poole 2014, 23-4). Crick (2011, 70-1) comments that often medieval commentators failed to discriminate between Merlin Caledonius and Merlin Ambrosius, and Merlinian prophecy circulated without precise attribution. For a probable instance of this confusion see Curley (1982, 220); Gunnlaugr might have drawn upon such a commentary. For references to Merlin Caledonius as king see Clarke’s edn of Vita Merlini (1973, 52-3).
