city in Italy destroyed by Attila in 452.
Fishburn and Hughes: "An ancient town in central Italy near the shores of the Adriatic, founded by the Romans in the second century BC. From its position it was a strategic base for expeditions to the north east of the Roman empire. In 12-10 BC, for example, during the wars against Pannonia, Augustus established himself for a time in Aquileia. In the third century it became an episcopal see; its bishops expounded The Three Chapters (a collection of writings on the divinity of Jesus). In 452 it was razed to the ground by Attila, king of the Huns. The presence of the Histrionic heresy in Aquileia, obviously apocryphal, could be an allusion to Pope Virgilius' condemnation of The Three Chapters in 548; they were later pronounced heretical at the Council of Constantinople in 553. Aquileia eventually broke with Rome, and its bishop Macedonius took the title Patriarch in defiance of Rome. It remained schismatic until the seventh century." (14)
