Brigantii
The Brigantii were a Gallic tribe who lived southeast of Lake Constance, in the area of present-day Bregenz, in Austria's state of Vorarlberg, during the Roman era.
Name
They are mentioned as Brigántioi by Strabo. An identification with the Brixentes, a tribe listed on the Tropaeum Alpium, has been proposed by Ernst Meyer.The ethnic name Brigantii is a Latinized form of Gaulish Brigantioi. It derives from the stem briganti-, meaning 'high, elevated', which can be compared with the name of their chief town Brigantion, also attested in other toponyms at the origin of the modern Briançon, Brégançon and Briantes. The same stem can also be found in name of the Celtic goddess Brigantia.
Geography
The Brigantii lived southeast of Lake Constance, in Raetia. Their territory was located north of the Vennones, west of the Estiones, east of the Lentienses.Their chief town was known as Brigantium. The settlement was located on the northeastern bay of Lake Constance, at an intersection of important east–west and north–south traffic routes. Late La Tène finds from the Ölrain plateau suggest the existence of a pre-Roman oppidum in the upper part of town.
