Egypt had by tradition a great variety of gods with a total of over 2000 of them, but many of them had similar characteristics and appeared all over the country by different names.
The huge diversity was due to the fact that before the country was united, the Nile Valley was divided into about forty self ruling areas where the ruling tribe had its own deities.
Almost all gods had one thing in common - they had a counterpart of the opposite sex and manifested themselves on earth through animals. Thus hundreds of birds, crocodiles, snakes, frogs, turtles, cows, cats etc. were considered to be the living images of a particular god and a natural and indestructible part of the environment in which people lived.
All parts of life were covered and there were gods for topics including beer, plants, digestion, the high seas, female sexuality, gardens, feasting and far, far more. Many of them had lots of duties and were in time combined with each other in a great number of ways. They could also appear in many forms like a goddess having a head of a wasp and body from a hippopotamus.
The goddesses are easy to single out in depictions - they always had their legs joined together, while the gods used to be shown striding.
All aspects of daily life were covered by at least one deity, and like people on earth they were members of families, were married and had children. They did most of the things that ordinary people did, like harvesting, hunting, eating, drinking, partying and even dying.
Most of them were depicted as men and women combined with the head of the animal by which they were represented and they could appear in different costumes and be represented by several animals in the Egyptian fauna.
For their names today we tend to know them by both their original Egyptian ones like Ra, Hathor and Amon, and the Greek forms like Isis, Anubis and Horus
