Thor (thôr or tôr), in Scandinavian myth, was the oldest son of Odin and Frigga and was the god of thunder. He ruled winds, seasons and agriculture. The Eddas speak of him as the champion of gods and men, hurling his thunderbolts at his enemies, — the monsters and giants. His weapon was an enormous hammer, which, after it was thrown, came back into his hand. He never grew weary. No matter how much strength he spent, it was renewed by a magic belt which he wore around his waist. Thursday is named from Thor.
