The ancient Egyptian Man-prisoner is one of the oldest hieroglyphs from Ancient Egypt. An iconographic portrayal from predynastic Egypt eventually led to its incorporation into the Egyptian language. Not only rebels from towns or districts, but foreigners from battle were being portrayed.
The nine bows concept of internal ancient Egyptian rebels, as well as 'foreign' rebels, began with actual bows, for example under Pharaoh Djoser's feet on his seated statue, 3rd dynasty; (his feet rest upon 9 bows). The more prolonged use of the 'prisoner' hieroglyph in language and iconography continued into New Kingdom, and Ptolemaic times with the prisoner hieroglyph, as a "foreign rebel people" presented and named inside of a " cartouche". The 'cartouche' was often identified on its perimeter ring with the fortifying blocks of a city fortification, representing either the people, or their city-state location.
