Hyde, in his Oriental Sports (1694), tells us one with eggs among the Christians of Mesopotamia on Easter Day and forty days afterwards, during which time their children buy themselves as many eggs as they can, stain them with a red colour in memory of the blood of Christ, shed as at that time of his crucifixion. Some tinge them with green and yellow.
Easter eggs are used as a Christian symbol to represent the empty tomb. The outside of the egg looks dead but inside there is new life, which is going to break out. The Easter egg is a reminder that Jesus will rise from His tomb and bring new life. Orthodox Christians dye boiled eggs red to make red Easter eggs that represent the blood of Christ shed for the sins of the world.
