Easter - Definition
n    “According to the eighth-century theologian the Venerable Bede (who came up with the dating system of AD and BC), Easter is named for Eostre, an Anglo-Saxon goddess of spring. She is associated with the egg and with the hare, both symbols of procreation that have been enduringly incorporated by the church in the form of Easter eggs and the Easter bunny who brings them.”
