Sampo

In Finnish mythology, the Sampo or Sammas was a magical artifact of indeterminate type constructed by Ilmarinen that brought good fortune to its holder. When the Sampo was stolen, it is said that Ilmarinen's homeland fell upon hard times and sent an expedition to retrieve it, but in the ensuing battle it was smashed and lost at sea.

The Sampo has been interpreted in many ways: a world pillar or world tree, a compass or astrolabe, a chest containing a treasure, a Byzantine coin die, a decorated Vendel period shield, a Christian relic, etc. In the Kalevala, compiler Lönnrot interpreted it to be a quern or mill of some sort that made flour, salt, and gold out of thin air. The world pillar hypothesis, originally developed by historian of religions Uno Harva and the linguist Eemil Nestor Setälä in the early 20th century, is the most widely accepted one.

According to Giorgio de Santillana, professor of the history of science at MIT, and student of mythology, the sampo and the world pillar both refer to the precession of the equinox. In Hamlet's Mill, co-authored with Hertha von Deschend, the authors find that the sampo or precession process was believed to grind out different world ages, from dark age to golden age and back again over the long precession cycle.
