Rota, the figure of a wheel, is the symbol of public roads reparied by order of the reigning prince, for the convenience of carriages, as in VIA TRAIANA. At the feet of Fortune, it signifies the mutability and inconstancy of that goddess. We see the wheel, beneath the chair of Fortune sitting, on coins of Sept. Severus, Caracalla, Gordianus Pius, Aurelianus, Gallienus, and other emperors, with the epigraph of FORTVNA REDVX.
