), a town of the Carnutes, a Celtic people. Their chief towns were Autricum and Genabum. Autricum seems to derive its name from the Autura, or Eure,
though the name Autura does not occur in any ancient writing; but the river is named Audura in the middle-age writings. Avaricum, Bourges,
is a name formed in like manner from the river Avara.
The position of Autricum is determined by two routes in the Table, though the name is miswritten Mitricum.
The place afterwards took the name of Carnutes or Carnutum, whence the name Chartres.
