It occurs to me that “Onhava” is a near-anagram, or one word-golf move, of “Avalon”, the mystical Isle of Arthurian legend.
Avalon was the home of Merlin and Morgan La Fay – a misty land of enchantment.
I am not terribly familiar with the Arthurian lore, but the sword in the stone and the grail legend fit the “Hero’s Journey” quest that is suggested in Pale Fire. There seem to be other parallels, e.g. Hazel and “The Lady of the Lake”.
Scott’s “Lady of the Lake” is not the Arthurian tale, but I just found out that Tennyson wrote a long Arthurian poem, “Idylls of the King” wherein the story of the lady of the lake and Merlin is told. The lady, who is actually a nymph has an affaire with Merlin, whom she eventually tricks and seals in a tree. Her name is “Vivian”. That makes me think of “Vivian Bloodmark” or “Calmbrood”. Merlin, of course, is a magician, a conjuror and an alchemist.
I’m wondering if has been noted before or if there are any other allusions or associations that anyone is aware of? Thanks
