The Peloponnesus resembles in figure the leaf of a plane tree.13 Its length and breadth are nearly equal, each about 1400 stadia. The former is reckoned from west to east, that is, from the promontory Chelonatas through Olympia and the territory Megalopolitis to the isthmus; the latter from south to north, or from Maliæ though Arcadia to Ægium.

The circumference, according to Polybius, exclusive of the circuit of the bays, is 4000 stadia. Artemidorus however adds to this 400 stadia, and if we include the measure of the bays, it exceeds 5600 stadia. We have already said that the isthmus at the road where they draw vessels over-land from one sea to the other is 40 stadia across.
