COLONIA Equestris, an ancient and noble colony on the Lacus Lemanus. It appears to be the work of Julius Cæsar, who settled there Equites Limatenses; 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 Gallie): hence its modern name.
