Julia Pacata was the daughter of Julius Indus, a 1st century nobleman of the Gaulish Treveri who helped put down a Gaulish rebellion in 21 AD and led an auxiliary cavalry unit in the Roman army, the Ala Gallorum Indiana. She married Gaius Julius Alpinus Classicianus, the procurator of Roman Britain from 61 to his death in 65. She buried him in London, and his reconstructed tombstone, which was re-used in the medieval wall of London, is now in the British Museum.
