エジプト中王国
The earliest known source for the "Instructions of Kagemni" is the Prisse Papyrus. This text dates to the much later twelfth dynasty of the Middle Kingdom of Egypt (perhaps by the reign of Amenemhat II from 1929 BC to 1895 BC, or a bit later in the twelfth dynasty). It is written in the Middle Egyptian language and in an archaic style of cursive hieratic.
