Strabo seems to ascribe the cutting through of the isthmus to the original colonists. But Thucydidês speaks of this isthmus in the plainest manner (iii, 81), and of the Corinthian ships of war as being transported across it. The Dioryktos, or intervening factitious canal, was always shallow, only deep enough for boats, so that ships of war had still to be carried across by hand or machinery (Polyb. v, 5): both Plutarch (De Serâ Num. Vind. p. 552) and Pliny treat Leukadia as having again become a peninsula, from the accumulation of sand (H. N. iv, 1): compare Livy, xxxiii, 17.
