Suttungr chasing Odin
After Odin had drank the mead of poetry, he changed into an eagly and flew away, chased by Suttungr, also in eagle form. When he reached Ásgarðr, he spat out the mead into the vats the Æsir had placed there. Still, Odin came so near to being caught by Suttungr that he urinated some mead out; this is called the poetaster's part.
