Late in the dynastic time-frame, the Egyptian gods were incorporated into the Greek and Roman pantheons. Towards the end of the pharaohic period the monotheistic belief systems of Christianity, Judaism and Islam supplanted the old gods. Finally, with the rush of science, for many, religion ceased to be the best rationalization. Ironically, the philosophic tenant of 'burden of proof' now drives science to furnish the huge amount of explanation a deity may need.

The Egyptian pantheon may economically be summarized:

Many myths surround the above, and vary with geographical location and period.
One of the oldest, Amon (god of Thebes, a fertility deity), was 'joined' with Ra (the sun god of Heliopolis) to form Amon-Ra.
Bastet, was a daughter of Ra (sometimes said to be his sister and consort) whose cult originated in Bubastis, the capital of a province of lower Egypt. Hathor, another daughter was thought to have been the 'eye of Ra'.
Anubis, the son of Ra (although later said to be the child of Osiris and Nephthys) supervised the burial of Osiris and so became associated with funeral rites. He is also said to have assisted in the judgement of the dead and is depicted with the head of a jackal.

Isis was the Egyptian mother goddess who was worshipped for more than 3000 years. Her cult later passed much of its imagery to the virgin Mary. Isis resurrected her brother Osiris after he was killed by his brother Seth. Osiris became god of the dead.
Horus was the son of Isis and Osiris, born after Osiris retired to the underworld.
Horus is depicted with the head of a falcon.
