托勒密王國
In 1990, more than 2,000 papyri written by Zeno of Caunus from the time of Ptolemy II Philadelphus were discovered, which contained at least 19 references to Arabs in the area between the Nile and the Red Sea, and mentioned their jobs as police officers in charge of "ten person units", and some others were mentioned as shepherds. Arabs in the Ptolemaic kingdom had provided camel convoys to the armies of some Ptolemaic leaders during their invasions, but they had allegiance to none of the kingdoms of Egypt or Syria, and they managed to raid and attack both sides of the conflict between the Ptolemaic Kingdom and its enemies.
