REGIUM Lepidum, Regium Lepidum, in Ancient Geography, a town of Cisalpine Gaul, on the Via Aemilia, so called from Aemilius Lepidus, who was consul with C. Flaminius; but whence it was surmised Regium is altogether uncertain. Tacitus relates, that at the battle of Bedriacum, a bird of an unusual size was seen perching in a famous grove near Regium Lepidum. Now called Reggio, a city of Modena. E. Long. 11. 0. N.
