Dictionary of Greek and Roman Geography/Acincum
ACINCUM, AQUINCUM (Άκούιγκον, Ptol. ii, 16. § 4; Tab. Peut; Orelli, Inscript, 506, 959, 963, 3924; Amm. Marc. xxx. 5; Itin. Anton.), a Roman colony and a strong fortress in Pannonia, where the legion Adjutrix Secunda was in garrison (Dion. Cass. lv. 24), and where also there was a large manufactory of bucklers. Acincum, being the centre of the operations on the Roman frontier against the neighbooring lazyges (Slovacs), was occasionally the head-quarters of the emperors. It answers to the present Alt-Buda, where Roman basements and broken pillars of aqueducts are still visible. On the opposite bank of the Danube, and within the territory of the lazyges, stood a Roman fort or outpost called, from its relative position, Contra-Acincum (Not. Imp.), which was connected with Acincum by a bridge. Contra-Acincum is named Πέσσιον by Ptolemy (iil 7. § 2). [ W. B. D. ]
