Right tributary of the Iberus  (modern Ebro) in Celtiberia (Celtiberi), modern Jalón. In its course, it passes Ocilis, Arcobriga, Aquae Bilbilitanorum, Bilbilis, Nertobriga  and Allobone. Its ice-cold water was especially suited for tempering iron (Mart. 1,49,12; 4,55,15; 12,21,1). In the Celtiberian Wars (2nd cent. BC), its valley was the base of operations for the Romans (App. Hisp. 188 ff.; ).
