MEGARIS (anc. geog.), the country of the Megareans, which Pliny makes a part of Attica; and Strabo says, some were of this opinion; but he himself makes it a distinct part; in which Scylax, Ptolemy, and the historians that relate the wars of the Athenians and Megareans, agree. It had Attica to the east, Bœotia to the north and west, and the Isthmus of Corinth to the south.
