a tributary of the Rhone, which rises in the Cévennes,
and is formed by two branches named respectively Gardon d'Alais
and Gardon d'Anduze,
from the names of these two towns. The Vardo flows in a deep valley, and passes under the great Roman aqueduct now named Pont du Gard,
below which it enters the Rhône
on the west bank, near a place named Cons.
The name Vardo occurs in Sidonius Apollinaris; and in a Latin poem of three or four centuries' later date the name is Wardo, from which the modern name Gardon
is formed, according to a common change of V into G. [VAPINCUM
