In a previous post "Zalig Paasfeest", I was very unkind to the Easter bunny, which I considered an unwanted intruder.
If Time is right, I might be wrong :
"Explanations for the Easter Bunny all seem to tie into the old Anglo-Saxon festival of Eastre, the spring goddess, whose symbol was, yes, a rabbit. A symbol of fertility, the rabbit became associated with the American celebration of Easter when the Germans who settled Pennsylvania in the 1700s brought from the motherland tales of the "osterhase," the mythical egg-laying bunny kids have grown to love. "

Those Pennsylvanian Germans have a lot to answer for ... but I still prefer the story of the church bells.
