Quariates
The Quariates or Quadiates were a Gallic tribe dwelling in the valley of Queyras, in the Alps, during the Iron Age.
Name
They are mentioned as Quariates by Pliny, and as Quadiatium and Quariat on inscriptions.The etymology of the name is obscure. Christian-Joseph Guyonvarc'h and Xavier Delamarre proposed to derive it from Celtic *kwario-, with sporadic preservation of the initial kw, attached to the suffix -ati-. Alexander Falileyev notes that the q-Celtic reflex remains problematic in this scenario.
The region of Queyras, whose castle is attested as Quadratum in the 12th century, may be named after the Gallic tribe.
