The Easter Bunny or Easter Rabbit (sometimes Spring Bunny in the U.S. is a character depicted as a rabbit bringing Easter eggs, who sometimes is depicted with clothes. In legend, the creature brings baskets filled with colored eggs, candy and sometimes also toys to the homes of children, and as such shows similarities to Father Christmas, as they both bring gifts to children on the night before their respective holiday. It was first mentioned in Georg Franck von Frankenau's De ovis paschalibus (About Easter Eggs) referring to an Alsace tradition of an Easter Hare bringing Easter Eggs.
Rabbits and hares
Eggs, like rabbits and hares, are fertility symbols of antiquity. Since birds lay eggs and rabbits and hares give birth to large litters in the early spring, these became symbols of the rising fertility of the earth at the Vernal Equinox.
Rabbits and hares are both prolific breeders. Female hares can conceive a second litter of offspring while still pregnant with the first. This phenomenon is known as superfetation. Lagomorphs mature sexually at an early age and can give birth to several litters a year (hence the saying, "to breed like bunnies"). It is therefore not surprising that rabbits and hares should become fertility symbols, or that their springtime mating antics should enter into Easter folklore.
The precise origin of the ancient custom of decorating eggs is not known, although evidently the blooming of many flowers in spring coincides with the use of the fertility symbol of eggs—and eggs boiled with some flowers change their color, bringing the spring into the homes. Many Christians of the Eastern Orthodox Church to this day typically dye their Easter eggs red, the color of blood, in recognition of the blood of the sacrificed Christ (and, of the renewal of life in springtime). Some also use the color green, in honor of the new foliage emerging after the long dead time of winter.
German Protestants wanted to retain the Catholic custom of eating colored eggs for Easter, but did not want to introduce their children to the Catholic rite of fasting. Eggs were forbidden to Catholics during the fast of Lent, which was the reason for the abundance of eggs at Easter time.
The idea of an egg-laying bunny came to the U.S. in the 18th century. German immigrants in the Pennsylvania Dutch area told their children about the "Osterhas", sometimes spelled "Oschter Haws"."Hase" means "hare", not rabbit, and in Northwest European folklore the "Easter Bunny" indeed is a hare, not a rabbit. According to the legend, only good children received gifts of colored eggs in the nests that they made in their caps and bonnets before Easter. In 1835, Jakob Grimm wrote of long-standing similar myths in Germany itself. Grimm suggested that these derived from legends of the reconstructed continental Germanic goddess *Ostara.
