Reading edition
“Goods were not obliged to make the circuit by Corinth; a direct road crossed the isthmus in the narrowest part, and they had even established there a system of rollers on which vessels of small tonnage were transported from one sea to the other.” (Strabo, VIII. ii. § 3.—Polybius, IV. 19.)
