This is also the origin of the Easter Bunny, and strangely, Easter Eggs (what? no chickens?!) - all life was thought to have originally come from an egg, and eggs were another favoured symbol of fertility. The "spirit" Easter Bunny/Hare was suppossed to lay its eggs in the grass, and people would go searching for them - the fore-runner of modern day Easter egg hunts.
