[dancing spawn of ungoliant]

i have read the Kalevala (our national epic) and the Shaman called Väinämöinen is a great wizard like Gandalf. i don't remember reading about a mighty ring in the Kalevala, but Väinämöinen had a kantele( Finnish musical instrument, originally with 5 strings over a horizontal sounding board, plucked by hand) witch possessed great powers.
Tolkien's elvish's pronaunciation is almost straight from Finnish (and Latin as far as i know).
He also "took" some parts to his writings of Norwegian and other Scandinavian myths.
