Odin's Island

When a gaggle of children on a small island between two Scandinavian countries meet Odin, they do not see the hoary rider of the clouds, summoning his warriors to battle, but only a little old man with a long white beard and one bright eye. One of his two horses has hurt its leg "in a meteor storm", and, though he has some difficulty explaining this to the people of the island (they seem curiously ignorant of the world outside), their native hospitality prompts them to help him. Alas, there is no "veterinarius" who can heal his horse's leg. He'd be better off going to a place they call "the continent". The sea has frozen over and so Odin treks across, braving the frost, to "South Norseland". In so doing, he effectively steps into the 20th century.
