The cross is always the central symbol, most clearly identifying it as the Paschal candle.The Greek letters alpha and omega signify that God is the beginning and the end. Five grains of incense (most often red) are embedded in the candle (sometimes encased in wax "nails") during the Easter Vigil to represent the five wounds of Jesus: the three nails that pierced his hands and feet, the spear thrust into his side, and the thorns that crowned his head.
The first eggs given at Easter were birds eggs. These eggs were painted in bright colours to give them further meaning as a gift.As chocolate became more wide spread in the 20th Century, a chocolate version of the traditional painted egg was developed. The size of the chocolate egg has grown over the years and is now more likely to be the size of an ostrich egg rather than a small bird's egg.
