Myrddin
MUR-THIN
Myrddin is the original Welsh form of the name better known as Merlin. It derives from the Brittonic elements 'mori' meaning sea and 'dunum' meaning fortress or hill fort, giving the overall meaning of sea fortress. Geoffrey of Monmouth latinised Myrddin as Merlinus in his 12th-century Historia Regum Britanniae to avoid unfortunate associations with a French word, and from there the name Merlin entered literary tradition. Myrddin in its Welsh form retains the full mythological weight of its Arthurian origins.
At a glance
The original Welsh form of Merlin, Myrddin means sea fortress and belongs to one of the most powerful figures in British mythology, the great wizard of Arthurian legend.
Etymology & History
Myrddin derives from Brythonic Celtic roots: 'mori' (sea) and 'dunum' (fortress or hill fort), reflecting the Celtic tradition of naming places after geographical features. The name originally referred to the town of Carmarthen in Wales, known in Welsh as Caerfyrddin, meaning Myrddin's fortress or sea fortress. The legendary figure of Myrddin was associated with this place. Geoffrey of Monmouth adapted the name to Merlinus to avoid its phonetic similarity to the Anglo-Norman word 'merde'.
Cultural Significance
Myrddin is one of the foundational figures of Welsh mythology, predating the Arthurian cycle that made Merlin famous worldwide. In early Welsh texts such as the Black Book of Carmarthen, Myrddin Wyllt appears as a wild, prophetic figure living in the forests after a traumatic battle. A separate tradition gave rise to Myrddin Emrys, the boy-prophet and later wizard of Arthurian legend. Both traditions fed into Geoffrey of Monmouth's Merlin. Using Myrddin rather than Merlin represents a deliberate embrace of the deep Welsh roots of this mythology, a name for those who want the original, not the medieval Latin translation.
