LIRI  , or GARIGLIANo (anc . Liris), a

river of central Italy, which rises at Cappadocia, 7 m . W. of Avezzano, and traverses a beautiful valley between lofty mountains, running S.S.E. as far as Arce . This valley is followed by the railway from Avezzano to Roccasecca . At Isola del Liri are two fine waterfalls . Below Ceprano, the ancient Fregellae, after it has issued from the mountains, the Liri is joined by the Sacco (anc . Trerus) formed by the union of several torrents between Palestrina and Segni, and the Melfa from the mountains N.E. of Atina, and runs E. through a broader valley . It then turns S. again through the mountains S.W. of the Via Latina (the line of which is followed by the modern railway to Naples), keeping W. of Rocca Monfina, and falls into the sea just below Minturnae, after a course of 104 m . It is not navigable at any point .
