abwatt replied to your post “Fictional character question: Merlin as a priest of Odin.”
I wouldn't. Myrddin is historically a Welsh name, suggesting a pre-Saxon origin story, and unlikely to be a devotee of a viking-era deity.
Yes, I am aware of that. Odin as a shape and god is akin to Woden/Wotan, which, when you consider Myrddin Wyltt as one of the prototypes for the Arthurian Merlin, things get interesting:
Myrddin Wyllt (Welsh: [ˈmərðɪn ˈwɨɬt]), Myrddin Emrys, Merlinus Caledonensis, or Merlin Sylvestris[1] (a legendary figure associated in some sources with events in the sixth century), is a figure in medieval Welsh legend, known as a prophet and a madman. He is the most important prototype for the modern composite image of Merlin, the wizard from Arthurian legend.
Texts about Myrddin Wyllt have similarities to an account of a north-British figure called Lailoken. He was probably born sometime around or in AD 540, and is said to have had a twin sister called Gwendydd or Gwenddydd or Languoreth. Myrddin Wyllt is said to have gone mad after the Battle of Arfderydd at Arthuret, which was waged between the victor Rhydderch Hael or Riderch I of Alt Clut and Gwenddoleu in AD 573.[1] He fled into the forest and lived with the animals. There he is said to have found his gift of prophecy
Arthuret is in Cumbria, which as is obvious from the name, is also related to Cymric - the term Welsh was also applied to the non Saxon Britons, specifically West Welsh. If we go with the image of Merlin as prophet-poet, then we get things more interesting:
vates (n.) 1620s, "poet or bard," specifically "Celtic divinely inspired poet" (1728), from Latin vates "sooth-sayer, prophet, seer," from a Celtic source akin to Old Irish faith "poet," Welsh gwawd "poem," from PIE root *wet- (1) "to blow; inspire, spiritually arouse" (cognates: Old English wod "mad, frenzied," god-name Woden; see wood (adj.)). Hence vaticination "oracular prediction" (c.1600).
Given also the legends of Myrddin being in the Forest of Caledonia, and the later links of Vikings with Northern Scotland, there's something interesting here. Myrddin as Brythonic poet-prophet linked to the madness of prototypical deity that became Odin to the Vikings - definitely something in the deep mythic structure here, down to the proto-Indo-European level
So yeah, while not historically accurate in description, in which I agree with abwatt, the theme is what I'll own, as a Cornishman less than an hour from the Cumbrian border, in an area where there have been Viking finds from the 8th Century - oh and who honours the old One Eye as an ancestral god!
