Region

Scandinavia & northern Europe

Period

Viking Age, 8th–11th c.

The gods of Asgard were worshipped by the Norse peoples of Scandinavia and by the Germanic tribes, especially during the Viking Age. Warriors sought to die in battle to reach Odin's Valhalla, and the myths were preserved in the Icelandic Eddas. The cult declined with the region's Christianization around the year 1000.

The Norse celebrated blóts, seasonal sacrifices with feasts of meat and mead, such as the Yule of the winter solstice. The great temple at Uppsala, in Sweden, hosted every nine years one of the largest sacrificial festivals of the Viking world.

At a glance

Jormungandr, the colossal Midgard Serpent of Norse cosmology, is the offspring of Loki and the giantess Angrboda, and sibling to Fenrir and Hel. Cast by Odin into the cosmic ocean encircling the inhabited world, it grew so immense that it grasped its own tail. Destined arch-nemesis of Thor, their titanic confrontation at Ragnarok ends in reciprocal annihilation.
