Horses in Germanic paganism
There was a significant importance for horses in Germanic paganism, with them being venerated in a continuous tradition among the Germanic peoples from the Nordic Bronze Age until their Christianisation. They featured in a number of diverse and interrelated religious practices, being one of the most common animals sacrificed in blóts and found in graves, notably in examples such as at Sutton Hoo and the Oseberg ship.
