I found a link but it turned up a different article. Google it. Easter is a religious holiday, but some of its customs, such as Easter eggs, are likely linked to pagan traditions. The egg, an ancient symbol of new life, has been associated with pagan festivals celebrating spring. From a Christian perspective, Easter eggs are said to represent Jesus' emergence from the tomb and resurrection. Decorating eggs for Easter is a tradition that dates back to at least the 13th century, according to some sources. One explanation for this custom is that eggs were formerly a forbidden food during the Lenten season, so people would paint and decorate them to mark the end of the period of penance and fasting, then eat them on Easter as a celebration.
The spring equinox celebration has been going on all over the world for at least the last 6,500 years and likely goes back to the beginning of the agricultural age of human civilization. Ester aka Eostre, Eastre, Ostara, like Santa Claus comes from Germanic paganism and is the root of the current spring celebration. The history of the modern spring celebration go back to when it was first changed by Jews to honor their exodus and called it Passover, later the early Christians, who had always celebrated the holiday as Jews or Pagans, changed it once again to honor the crucifixion of Jesus. The rabbit and eggs have always been seen as symbols of fertility, the Pagans actually used phallic symbols as well, I guess we can thank uptight early Christians for removing those. The bunny came first, Jesus came second. Leave the poor bunny alone.
