Decorating eggs has been going on for many years. Ostrich eggs engraved have been found in Africa 60,000 years ago and in Egypt, eggs were decorated with both silver and gold within the last five thousand years.
From what I have been able to ascertain, the Easter egg represents Jesus empty tomb and have been adopted as a symbol of Christ rising from the grave. While there is without a doubt a significance to the tradition, it is also just plain fun.
With grandchildren around we followed the tradition ourselves today and had a wonderful celebration on the farm on this the most holy day of the Christian faith! All eggs were found and chocolate quickly consumed or put away for later.
I hope you have found some traditions for your own family. May you have a blessed Easter wherever you may be!
