Rabbits and Eggs are fertility symbols. Rabbits were once believed to be hermaphrodites and it was also believed they could reproduce without sex. Birds lay eggs and rabbits give birth in large litters in early spring, the two became symbols of rising fertility of the earth at the March Equinox.
Ēostre or Ostara (Northumbrian Old English: Ēostre; West Saxon Old English: Ēastre; Old High German: *Ôstara) is a goddess in Germanic paganism who, by way of the Germanic month bearing her name is the namesake of the festival of Easter.
The fertility symbols (rabbit, egg), the word Ēostre ( sounds a lot like Easter doesn't it), were incorporated into Christianity. I could care less. It is a lovely holiday. There are not nearly enough holidays in the spring.
Lets take a look at some public domain Easter cake and cupcake images. Maybe they will inspire you to make a cake at home this year.
