The Easter bunny is German in origin. It was in the 16th century the bunny was mentioned in literature as a deliverer of eggs. Eggs are a symbol of rebirth and fertility. Sun was seen as a miracle when it returned after winter and the egg is seen as the symbol of that. Christanity would later taken this as the symbol of Jesus’ resurrection. Young comments that the Easter bunny is: a continuation of the reverence shown during the spring rites to the rabbit as a symbol of abundance. The honouring of such emblems of fertility extended to eggs. The egg serves as a representation of new life. It stands for the renewing power of nature and, by extension, agriculture. The egg can also symbolize regeneration in a spiritual or psychological sense. The ritual of colouring Easter eggs stems from the tradition of painting eggs in bright colours to represent the sunlight of spring. Young also talks about finding your inner bunny 😉 (Good luck with that)
