Helvii (Gauls)

The Helvii (also Elui, ancient Greek Ἑλουοί) were a relatively small Celtic polity west of the Rhône river on the northern border of Gallia Narbonensis. Their territory was roughly equivalent to the Vivarais, in the modern French department of Ardèche. Alba Helviorum was their capital, possibly the Alba Augusta mentioned by Ptolemy, and usually identified with modern-day Alba-la-Romaine (earlier Aps). In the 5th century the capital seems to have been moved to Viviers.
