The Romans believed that "All life comes from an egg." Ancient Christians considered eggs to be "the seed of life" symbolic of the resurrection of Jesus Christ. In ancient Egypt, Greece, Rome and Persia eggs were dyed for spring festivals. In medieval Europe, beautifully decorated eggs were given as gifts. Today hundreds of novel methods of decorating Easter eggs have been invented, and during the week of Easter about 30 million more eggs are sold compared to any other week of the year.
