Perhaps, one of the few ancient communities who regarded animals as sacred was the Egyptian community. It is interesting to study about the animals of Ancient Egypt.
Cats were worshipped by the people. Bastet was the cat goddess. Cat mummies are found out in large numbers. Cats were popular companions of the people.
A bull represented power, aggression and masculinity. A cow's quiet demeanour suggested a gentle aspect of feminine beauty. Her gift of milk was considered important.
The lion was connected with the rising and the setting of the sun, and so were thought to be guardians of the horizon and were linked to solar deities.
In Ancient Egypt, the fish had both sacred and scorned species. Some were sacred in some places and not allowed to be eaten, whereas in other places, anyone could eat the fish. Some of the fish in Egypt included the carp, perch and catfish.
