in North Gallia, a name which appears in the Table on a road which passes from Augustomagus (Senlis
) through Calagum (Chailli
). Riobe comes after Calagum, but the distance is not given.
A road, which appears to be in the direction of a Roman road, runs from Chailli
a few miles north of the Seine
; and D'Anville thinks that the name Orbi
and the distance from Riobe to Condate (Montereau-sur-Yonne
) enable us to fix Riobe at Orbi.
