Ukko (the ancient or honorable) was the chief god of the Finns, "the celestial old man," 'the god of heaven." He was the first of the trinity composed of himself, Wainiamoinen, and Ilmarinen. He appeared sometimes even as a first principle, whence his surname of Ylijumala, "the supreme god." In case of wounds, the secondary deities were resorted to for a cure; but, in order to complete and consolidate the work of the lesser divinities, the intervention of Ukko was needed. — The cure of a wound needing the formation of new flesh was considered a regular act of creation, and therefore the help of the creative power himself was necessary.
