International? Easter in Japan? Easter anywhere that isn't primarily Christian? I think not...The hare was a popular motif in medieval church art. In ancient times, it was widely believed (as by Pliny, Plutarch, Philostratus, and Aelian) that the hare was a hermaphrodite. The idea that a hare could reproduce without loss of virginity led to an association with the Virgin Mary. 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 which was tagged as Easter, not so much with the squirrels.
