Finland Summertime

Before 1316 the summer solstice was called Ukon juhla after the Finnish god Ukko. In Karelian tradition, many bonfires were burned side by side, the biggest of which was called Ukko-kokko (the "Old Man Bonfire"; the prefix ukko- is used in Finnish to denote notable or particularly large objects or entities).
