Easter Costumes & Accessories. The most joyous of Christian festivals, and one of the first celebrated by the Christians, commemorates the resurrection of Jesus Christ, on the first Sunday after the full moon following the vernal equinox. The practice of eating eggs on Easter Sunday and giving them as gifts to friends and children probably arose because, in the earlier days of the church, eggs were forbidden food during Lent (the 40 days before Easter) and were therefore always eaten on Easter Sunday. But the custom of coloring eggs goes back to the ancient Egyptians and Persians, who practiced this custom during their spring festival.
Through the fact that the Egyptian word for hare, "un", means also "open" and "period", the hare became associated with the idea of periodicity, both lunar and human, and so became a symbol of fertility and of the renewal of life. As such, the hare became linked with the Easter, or paschal, eggs. In the U.S. the Easter rabbit is fabled to lay the eggs in the nests prepared for it or to hide them for the children to find.
