They are mentioned as
Coriosolitas (var.
coriosolitos,
curiosolitas,
curiosolitas) and
Coriosolites (var.
coriosultes,
coricoriosuelites,
cariosu-) by
Caesar (mid-1st c. BCE), and as
Coriosvelites by
Pliny (1st c. CE). The etymology of the
ethnonym Coriosolites remains uncertain. The first element is certainly the
Gaulish root
corio- ('army, troop'), derived from
Proto-Indo-European *
kóryos ('army, people under arms'). However, the meaning of the second element is unclear.
Pierre-Yves Lambert has proposed to interpret
corio-solit-es as 'those who purchase (or sell) mercenaries', by positing a Gaulish stem
solitu- ('purchase/salary of mercenaries'; cf. Gaul.
soldurio- < 'body-guard, loyal, devoted',
OBret. solt '
solidus'). Alternatively, a connection with the Gaulish stem
sūli- ('[good] sight'; cf.
OIr. súil, 'sight',
Britt. Sulis) has also been conjectured, with
corio-soli-tes as the 'troop-watchers', 'those who watch over the troop'. The city of
Corseul, attested ca. 400 AD as
civitas Coriosolitum ('
civitas of the Curiosolites',
Aecclesia Corsult ca. 869,
Corsout in 1288) is named after the Gallic tribe. == Geography ==
