Investigate the symbolism of the egg

The egg is very symbolic in Christianity.

The oldest tradition is to use dyed and painted
chicken eggs, but a modern custom is to substitute chocolate eggs.

Eggs, in general, were a traditional symbol of fertility, and rebirth.

In Christianity, they symbolise the empty tomb
of Jesus though an egg appears to be like the stone of a tomb, a bird hatches from it with life; similarly, the Easter egg, for Christians, is a reminder that Jesus rose from the grave, and that those who believe will also experience eternal life.

The link between eggs and Easter derives from the Christian tradition of fasting through Lent, the 40 days before Easter Sunday.

According to Christian tradition, Lent begins on Shrove Tuesday, or
Pancake Day as we know it today. In past times, Shrovetide celebrations
lasted for four days, beginning on the Saturday when eggs were given as
gifts to children.‘Egg Saturday’ was followed by Shrove Sunday, Collop Monday
and finally Shrove Tuesday, when the remaining fat and eggs were used
up to make pancakes.

During Lent the eating of animal products, including eggs, was strictly
forbidden. However, hens continued to lay throughout the fast, resulting
in a large stock for Easter Sunday.

The custom of exchanging decorative eggs was prevalent in many of
the world’s ancient civilizations. Eggs were regarded as a symbol of the
universe or a creation of God. They also represented fertility, resurrection
and new life.

In some parts of Europe, scarlet Easter eggs are planted in the
fields and vineyards to protect crops from thunder and hail.
