Maat or ma’at (thought to have been pronounced *[muʔ.ʕat]), also spelled māt or mayet, was the ancient Egyptian concept of truth, balance, order, law, morality, and justice. Maat was also personified as a goddess regulating the stars, seasons, and the actions of both mortals and the deities, who set the order of the universe from chaos at the moment of creation. Her (ideological) counterpart was Isfet.
The earliest surviving records indicating Maat is the norm for nature and society, in this world and the next, were recorded during the Old Kingdom, the earliest substantial surviving examples being found in the Pyramid Texts of Unas (ca. 2375 BCE and 2345 BCE).
