One of my favorite paintings I saw in Jerusalem was at this church on the mount of olives. It is the Russian Orthodox Church: Church of Mary Magdalene.
Christians embraced the egg symbol and likened it to the tomb from which Christ rose. Saint Augustine first described Christ’s Resurrection from the dead as a chick bursting from an egg. This symbolism was enhanced in the Christian East’s celebration of Easter. At the end of the Paschal Liturgy, the faithful exchange paschal greetings and the priest and the faithful present each other with red eggs. Wooden eggs are sometimes suspended from hanging lamps and chandeliers, and often the faithful decorate wooden eggs with icons and hang them from the vigil lights in their homes.
I don't know about the truth of any of this*, however, it was a magnificent painting and a great story of her witness of Christ's Resurrection.
