In 23 BC the Roman governor of Egypt, Publius Petronius, to end the Meroitic raids, invaded Nubia in response to a Nubian attack on southern Egypt, pillaging the north of the region and sacking Napata (22 BC) before returning home. In retaliation, the Nubians crossed the lower border of Egypt and looted many statues (among other things) from the Egyptian towns near the first cataract of the Nile at Aswan. Roman forces later reclaimed many of the statues intact, and others were returned following the peace treaty signed in 22 BC between Rome and Meroe.
