Pohjola in the context of Anna-Leena Siikala

The Kalevala (IPA: [ˈkɑleʋɑlɑ]) is a 19th-century compilation of epic poetry, compiled by Elias Lönnrot from Finnish, Karelian and Ingrian folklore and mythology, telling a 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 mythical wealth-making machine Sampo.

The Kalevala is regarded as the national epic of Finland and Karelia, and is one of the most significant works of Finnish literature along with J. L. Runeberg's The Tales of Ensign Stål and Aleksis Kivi's The Seven Brothers. The Kalevala was instrumental in the development of the Finnish national identity and the intensification of Finland's language strife that ultimately led to Finland's independence from Russia in 1917. The work is known internationally and has partly influenced, for example, J. R. R. Tolkien's legendarium (i.e. Middle-earth mythology, especially The Children of Húrin).

Louhi (Finnish pronunciation: [ˈlou̯hi]; alternate names include Loviatar (Finnish pronunciation: [ˈloʋiɑtɑr]), Loveatar, Lovetar, Lovehetar, Louhetar and Louhiatar) is the ruler of Pohjola in Finnish mythology. She is regarded as a goddess of death and disease. She is also the mother of wolves. Her original role was likely as the ruler of the underworld.

In Kalevala, Elias Lönnrot split Louhi into two different characters, Louhi and Loviatar, describing Louhi as a wicked queen of Pohjola and Loviatar as a blind daughter of Tuoni. In Runo 45 of the Kalevala, Loviatar is impregnated by a great wind and gives birth to nine sons, the Nine diseases.

In Finnish mythology, the Sampo (pronounced [ˈsɑmpo]) or Sammas (pronounced [ˈsɑmːɑs]) is a magical device or object described in many different ways, constructed by the blacksmith, inventor and originally the sky god Ilmarinen, and which brings riches and good fortune to its holder, akin to the horn of plenty (cornucopia) of Greek mythology. A central myth in Finnish mythology is the idea that the sampo was once in Pohjola but a group of heroes attempt to steal it. Sammas, as something at the center of the world, also exists in Estonian mythology.

The Sampo or Sammas has multiple other names in runic songs as well, including Samppu, Samppi and Kirjokansi (pronounced [ˈkirjoˌkɑnsi]).

Finnish mythology commonly refers to 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.

Finnish mythology survived within an oral tradition of mythical poem-singing and folklore well into the 19th century.
