COLONIA Equestris, an ancient and noble colony on the Lacus Lemanus. It appears to be the work of Julius Cæsar, who settled there Equites Limitanei; and to this Lucan is thought to refer. By the Itinerary it is supposed to have stood between Lausanne and Geneva, 12 miles from the last place by Peutinger's map; which directs to Nyon, placed in Cavo Lemano, according to Lucan's expression, that is, a bay or cove of the lake. Its ancient name was Noviodunum, (Notitia Galliae): hence its modern name.
