CLODIA, VIA, an ancient high-road of Italy. Its course, for the first I I m., was the same as that of the Via Cassia; it then di verged to the north-north-west and ran on the west side of the Lacus Sabatinus, past Forum Clodii and Blera (mod. Bieda) to Tuscania, after which its course is uncertain. According to Millee (Itineraria Romana) it went on by Maternum (Valentano) Ac quapendente, Radicofani, Buonconvento Siena, and Luca past another Forum Clodii to Luna : but this is doubtful. In parts it follows older Etruscan roads, and may date from the end of the 4th century B.C. See also CASSIA, VIA.
