“ Achrida, A titular see in Upper Albania, the famous metropolis and capital of the medieval kingdom of Bulgaria, now the little village of Ochrida, on the Lake of Ochrida, the ancient Lacus Lychnitis, whose blue and exceedingly transparent waters in remote antiquity gave to the lake its Greek name. The city was known in antiquity as Lychnidus and was so called occasionally in the Middle Ages. In the conflicts of the Illyrian tribes with Rome it served the former as a frontier outpost and was later one of the principal points on the great Roman highway known as the via Egnatiana. ”
