Comacchio
Comacchio, a walled town of Italy, 30 miles S.E. of Ferrara, on the sea-side of an island in the east of a lagoon about 90 miles round, shut out from the Adriatic by a belt of land three miles wide. It is the seat of a bishopric, and has several churches, and a Capuchin convent. The chief industries are salt-works and fisheries, the fry of eels and grey mullet being let in by canals and kept in by nets. Tasso and Ariosto both mention the fish of Comacchio.
