Volubilis is a partly-excavated Berber-Roman city in Morocco situated near the city of Meknes that may have been the capital of the Kingdom of Mauretania, at least from the time of King Juba II.
Oea was an ancient city in modern-day Tripoli, Libya, founded by the Phoenicians in the 7th century BC. It became a Roman-Berber colony in the second half of the 2nd century BC.
The monument was dedicated by two brothers, one of them being the Pater of his community.
