More on the origins of Easter....

The English word Easter and the German Ostern come from a common origin (Eostur, Eastur, Ostara, Ostar), which to the Norsemen meant the season of the rising (growing) sun, the season of new birth. The word was used by our ancestors to designate the Feast of New Life in the spring. The same root is found in the name for the place where the sun rises (East, Ost). The word Easter, then, originally meant the celebration of the spring sun, which had its birth in the East and brought new life upon earth. This symbolism was transferred to the supernatural meaning of our Easter, to the new life of the Risen Christ, the eternal and uncreated Light. Based on a passage in the writings of Saint Bede the Venerable (735), the term Easter has often been explained as the name of an Anglo-Saxon goddess (Eostre), though no such goddess is known in the mythologies of any Germanic tribe. Modern research has made it quite clear that Saint Bede erroneously interpreted the name of the season as that of a goddess.
