C. Marcius, one of the haughtiest leaders of the patrician party at Rome in the early ages of the republic. His name is associated with one of the most beautiful of the legends which adorn that period of Roman history. This legend will be found detailed in full under the article Roman History. See also Coriolli.

Coriolli, an ancient Latin city, celebrated as giving a surname to the Roman C. Marcius. Coriolli is first mentioned in Roman history as falling into the hands of the Volsci, and being retaken from them by the Romans, B.C. 493. When Coriolanus made common cause with the Volsci against his countrymen, this city was one of the first that yielded to his victorious arms. It was never a very large or important place, and seems to have dropped out of existence before the close of the fifth century B.C. The site of Coriolli is now unknown. Some geographers have assigned it to the hill called Monte Giove about nineteen miles from Rome on the way to Antium. Others have suggested a hill four miles nearer Antium as a more plausible locality.
