TYPE Roman Empire, Augustus (27 BC - 14 AD), silver denarius, Colonia Patricia (Spain) mint, struck 17-16 BC, 3.25g DESCRIPTION . Obv: Bare head of Augustus to right, legend 'SPQR CAESAR AVGVSTO' Rev: Augustus in quadriga on triumphal arch of two portals and four viaducts, crowned by Nike from behind, legend [QVOD] VIAE MVNT SVNT REFERENCE: S2K 1631, RSC 233, RIC 318, BMC 4463, VM 75 GRADING: VF / F+, some porosity, toned, scarce ORDER INFO: R3115, $300 Interesting and scarce architectural type, celebrating Augustus' extensive road-building in Italy (and perhaps also in Spain), and underscored by the reverse inscription, meaning "for the roads that were presented". Depicted on the reverse is a structure erected in honor of these achievements - possibly in Spain, but more likely in Italy and conjectured even as the famous Milvian Bridge that carried the Via Flaminia across the Tiber just north of Rome. Historian Dio Cassius writes about the erection of "statues on arches on the bridge over the Tiber" commemorating the emperor's personal generosity behind this great construction undertaking.
