The Segusini (Gaulish: *Segusinoi, 'those of Segusio') were a Gallic tribe dwelling around present-day Susa, in the Alpes Cottiae, during the Iron Age.
Name They are mentioned, in genitive case, as Segosianō̃n (Σεγοσιανῶν) Strabo (early 1st c. AD),Strabo. Geōgraphiká, 4:1:11. as Segousianō̃n (Σεγουσιανῶν) Ptolemy (2nd c. AD),Ptolemy. Geōgraphikḕ Hyphḗgēsis, 3:1:36. as Segusinorum on the Arch of Susa,CIL 5:7231. and, in nominative case, as Segusinae on an inscription.CIL 5:7250., s.v. Segusini.The Greek genitive plural suffix -ῶν is related to various forms of the nominative case, but the Latin genitive -orum is incompatible with the nominative -ae.
The ethnonym Segusini is a Latinized form of Gaulish *Segusinoi. It means 'the people of Segusio', itself from the root sego- ('victory, force').
Geography
The Segusini dwelled in the valley of the Duria, around Segusio (modern Susa). The Barrington Atlas locates their territory east of the Medulli and Belaci, south of the Acitavones, and west of the Iemerii and Taurini., Map 17: Lugdunum.
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.
History They are attested on the Arch of Susa, erected by Cottius in 9–8 BC.
