Tapio (spirit)
Tapio is an East Finnish forest spirit or god, who figures prominently in the Kalevala. Hunters prayed to him before a hunt. His wife is the goddess of the forest, Mielikki. He was the father of Annikki, Tellervo, Nyyrikki (the god of hunting), and Tuulikki. Fitting the Green Man archetype, Tapio has a beard of lichen and eyebrows of moss.
He lends his name in the form of Tapiola to: (a) one of the major urban centres within the city of Espoo, outside of Helsinki; and (b) an unincorporated community in the USA state of Michigan. He also appears in the Nightwish song, Elvenpath, as Tapio, bear king, ruler of the forest.
Jean Sibelius's tone-poem Tapiola (1926) is a depiction of the forest Tapio inhabits.
