Frey. (Scandinavian mythology.) The god of the sun and of rain, and hence of fertility and peace. He was one of the most popular of the Northern divinities. No weapons were ever allowed in Frey's temple, although oxen and horses were sacrificed to him. His name was connected with the taking of any solemn oath, a heavy gold ring was dipped in the blood of the sacrifice and the oath sworn upon the ring. One of the most celebrated of the temples built to Frey was at Therva in Iceland.
