Another interesting comparison I’ve drawn between Bosmer/Altmer and Welsh lore pertains to the figure of ‘The Wilderking’.
The Wilderking is primarily worshipped by bosmeri tribes in Greenshade (Mirkwood, anyone?) and the look of his crown and his elusiveness leads him to be depicted as an altmer with antlers. The Thranduil vibes are popping off. Would.
But where would this idea of an elusive, elfin king of the forest come from?
There is an overlap between Welsh and Germanic folklore regarding something called ‘The Wild Hunt’.
In y Cymru, the head of the Wild Hunt is ‘Gwyn ap Nudd’ (White Son of the Mist) alluding to his elusive nature as a faerie, otherwise known as ‘Arawn’, the King of the Otherworld/Annwfn. He is often depicted with antlers (or a crown that resembles antlers), and is closely tied to figures like Herne (English), Woden (Anglo Saxon) and Cernunnos (Gaulish).
In a 14th Century manuscript condemning the Welsh divinatory traditions, it is said that the soothsayers said this before entering a forest:
“To the King of the Faeries, and to his Queen: Gwyn ap Nudd, thou who art far in the forest, for the love of your consort, permit us to enter thy dwelling.”
To take a German route, I’m reminded of a favourite poem of mine: though he’s not a god (but inspired, most certainly, by Gwyn ap Nudd), we have Goethe’s ‘Erlkönig’ - the Erl King. I’ll link the poem below:
