 Early pies were in the form of flat, round or freeform crusty cakes called galettes consisting of a crust of ground oats, wheat, rye, or barley containing honey inside.These galettes developed into a form of early sweet pastry or desserts, evidence of which can be found on the tomb walls of the Pharaoh Ramesses II, who ruled from 1304 to 1237 BC, located in the Valley of the Kings.Sometime before 2000 BC, a recipe for chicken pie was written on a tablet in Sumer.
