Territory The Segovellauni dwelled in the valley of the
Rhône river, south of the
Isère river and west of the
Vercors Massif, around the present-day city of
Valence. This land, corresponding to the modern
Valentinois region, was called the 'Island' by
Polybius and
Livy in their description of
Hannibal's crossing of the Alps in 218 BC, for it was situated between the Rhône and the Isère, near the confluence of the two rivers. In the south, their territory stretched down to the
Drôme river, or perhaps further south into the plain of
Montélimar. It likely covered the
Vivarais region west of the Rhône, between the rivers
Eyrieux and
Doux. They lived south of the
Allobroges, north of the
Helvii,
Tricastini and
Vocontii, east of the
Vellavi, and west of the
Vertamocorii and
Tricorii. The Segovellauni were in control of a section of the Isère
river mouth, from which they were able to hold the Allobroges at bay. Like the Tricastini and
Memini, they nonetheless lived as clients of the neighbouring
Cavari as part of their confederation.
Settlements The location of the pre-Roman chief town of the Segovellauni has been debated in scholarship, but it is traditionally ascribed to the oppidum of Malpas (
Soyons), on the west bank of the Rhône. During the Allobrogian revolt of 62 BC, the Roman legate Manlius Lentinus stationed troops in the territory of the Segovellauni, near an oppidum named Ventia. Although its location remains obscure, some scholars have proposed to identify Ventia with Malpas, which would explain why the Roman legates Lucius Marius and Servius Galba "crossed the Rhone" towards the territory of the Allobroges, itself located between the Rhône and the Alps, in
Cassius Dio's account of the events. In the second part of the 1st century BC, the Segovellauni were absorbed into the
civitas Valentinorum (or
colonia Valentia), founded under
Caesar or
Augustus. According to Stephen L. Dyson, a border land around their capital, Valentia (modern
Valence), seems to have been detached from the territory of the Cavari and given to the smaller Segovellauni by the Romans, since
Pliny (1st c. AD) described the settlement as
in agro Cavarum, whereas
Ptolemy (2nd c. AD) had it belonging to the Segovellauni. == History ==
