Karnak is the home of the god Amon who was an insignificant local god until the 12th dynasty when Thebes became the capital of Egypt. He was represented in his original state as a goose and later as a ram, at the height of his power he was shown as a human with a head dress of feathers - all that remained of the goose.
In ancent times wars were not fought between countries but were considered as contests between gods. One deity subduing and replacing another, the victorious god and its people growing in strength. This is how Amon, with the help of Thutmose III and various other New Kingdom kings, rose to become the first supreme god of the known world and was hailed as God of gods. Little is know of him, unlike most other gods he has no legends or miracles to impress his worshippers and seems to be closer to an abstract idea of a godhead. His followers came from all the strata of society and he was known to some as 'Vizier of the poor.'
All Egyptian temples had a sacred lake, Karnak's is the largest. It was used during festivals when images of the gods would sail across it on golden barges. Karnak was also the home of a flock of geese dedicated to Amon.
