Kom Ombo, which means "a collection of gold", is uniquely dedicated to two gods: Horus the Falcon and the Crocodile God, each with its trinity of god, wife, and son. There are two of everything, with side by side courtyards and inner sanctums, each side mirroring the other. On the grounds of the Temples is the Nile-o-Meter, a well-like structure used to measure the height of the Nile and determine what taxes would be levied each year. It the level of the Nile was high, taxes were high; when the level was low, taxes were low.
There is also in the Temple a calendar incised into the walls showing what the king would do each day. There were 365 days with 12 months of 30 days each, making up 3 weeks of 10 days each. There were 5 days leftover at the end of the year.
