The Kalevala is a 19th-century compilation of epic poetry, compiled by Elias Lönnrot from Karelian and Finnish oral folklore and mythology, telling an epic story about the Creation of the Earth, describing the controversies and retaliatory voyages between the peoples of the land of Kalevala called Väinölä and the land of Pohjola and their various protagonists and antagonists, as well as the construction and robbery of the epic mythical wealth-making machine Sampo.

In Finnish mythology, the Sampo is a magical device or object described in many different ways that was constructed by the blacksmith Ilmarinen and that brought riches and good fortune to its holder, akin to the horn of plenty (cornucopia) of Greek mythology. When the Sampo was stolen, Ilmarinen's homeland fell upon hard times. He sent an expedition to retrieve it, but in the ensuing battle it was smashed and lost at sea.
Finnish mythology commonly refers of the folklore of Finnish paganism, of which a modern revival is practiced by a small percentage of the Finnish people. It has many shared features with Estonian and other Finnic mythologies, but also with neighbouring Baltic, Slavic and, to a lesser extent, Norse mythologies.

Ilmarinen, a blacksmith and inventor in the Kalevala, is a god and archetypal artificer from Finnish mythology. He is immortal and capable of creating practically anything, but is portrayed as being unlucky in love. He is described as working the known metals of the time, including brass, copper, iron, gold, and silver. The great works of Ilmarinen include the crafting of the dome of the sky and the forging of the Sampo. His usual epithet in the Kalevala is seppä or seppo ("smith"), which is the source of the given name Seppo.
