After the fall of the Amarna dynasty, the original Egyptin pantheon was the main religion, until the development Coptic Christianity and later Islam, even though the Egyptians continued to have relations with the other monotheistic cultures (the Hebrews). Egyptian mythology put up surprisingly little resistance to the spread of Christianity. This is sometimes explained by saying that Jesus was originally a syncretism based mainly on Horus, with Isis and her worship becoming Mary.
