Others have attributed the name instead to the Greek root tarvos, meaning "bull".Tarvisium, then a city of the Veneti, became a municipium in 89 BCE after the Romans added Cisalpine Gaul to their dominions. Citizens were ascribed to the Roman tribe of Claudia. The city lay in proximity of the Via Postumia, which connected Opitergium to Aquileia, two major cities of Roman Venetia during Ancient and early medieval times. Treviso is rarely mentioned by ancient writers, although Pliny writes of the Silis, that is the Sile River, as flowing ex montibus Tarvisanis.
