 The name of Andragoras is uncommon, and the only other reportage of the name is in the Greek papyri from Ptolemaic Egypt, thus the identification of the two is not far-fetched.Andragoras was later appointed governor of the frontier province of Parthia, which had been merged with the neighboring province of Hyrcania since the conquest of the Achaemenid Empire by the Macedonian ruler Alexander the Great in 330 BC.Parthia was during this period constantly receiving new waves of Iranian migrants from Central Asia, most notably the Parni led by Arsaces I.
