They are mentioned as Segosianō̃n (Σεγοσιανῶν) Strabo (early 1st c. AD),[1] as Segousianō̃n (Σεγουσιανῶν) Ptolemy (2nd c. AD),[2] as Segusinorum on the Arch of Susa,[3] and as Segusinae on an inscription.[4][5]
The ethnonymSegusini is a latinized form of Gaulish *Segusinoi. It means 'the people of Segusio', itself from the root sego- ('victory, force').[5]
Their chief town, Segusio, controlled the route over Mont Genèvre and served as the gateway into the Italian Peninsula. Segusio possessed Latin law probably from the time of Augustus (27 BC–14 AD) and was a municipium from the time of Nero (54–58 AD). It was conquered by Constantinus in 312 AD.[9]
