Archaeology has turned up some itinerary material in unexpected places. The Vicarello Cups, four silver cups dated to 1st century AD which were found by workmen excavating a foundation at Bracciano 30 kilometres (19 miles) northwest of Rome in 1852, are engraved with the names and distances of 104 stations on the road between Gades (modern-day Cadiz) and Rome, covering in total a distance of 1,840 1840 Roman miles (2,723.2 km (1,692.1 mi)). Believed to be a votive offering by merchants travelling from Gades to Rome, the inscription is a valuable source of information about the road network at the time, and scholars refer to this artefact as Itinerarium Gaditanum.
