The name 'Sampo' originates from Finnish mythology, where it refers to a magical artifact created by the smith god Ilmarinen. This artifact, often described as a mill or a device of great power, was believed to bring riches and good fortune to its holder, similar to the cornucopia in Greek mythology. The Sampo's theft and subsequent destruction led to significant hardship for Ilmarinen's homeland, highlighting its importance in mythological narratives.
