Through his parents, Ptolemy had Roman citizenship and they sent him to Rome to be educated. His mother likely died in 5BC and was placed in the Royal Mausoleum of Mauretania, built by his parents. In Rome, Ptolemy received a good Roman education. He was part of the remarkable court of his maternal aunt Antonia Minor, an influential aristocrat who presided over a circle of various princes and princesses which assisted in the political preservation of the Roman Empire's borders and affairs of the client states. Antonia Minor, the youngest daughter of Mark Antony and the youngest niece of Emperor Augustus, was a half-sister of Ptolemy's late mother, also a daughter of Mark Antony. Antonia Minor's mother was Octavia Minor, Mark Antony's fourth wife and the second sister of Octavian (later Augustus). Ptolemy lived in Rome until the age of 21, when he returned to the court of his aging father in Mauretania.
