Geographically the Peloponnesus well deserves the name of island, which was bestowed upon it by the ancients. The low Isthmus of Corinth completely severs it from the mountainous peninsula of Greece. It is a world in itself, small enough as far as the mere space is concerned which it occupies upon the map, but great on account of the part it has played in the history of humanity. {57} On entering the Peloponnesus from the Isthmus of Corinth, we see rising in front of us the mountain rampart of Oneium, which defended the entrance of the peninsula, and upon one of whose promontories was built the nearly impregnable citadel of Corinth. These mountains form part of the general mountain system of the whole island, and, sheltered by them, its inhabitants could live in security. The principal mountain mass, whence all other chains radiate towards the entrances of the peninsula, is situated in the interior of the country, about forty miles to the west of Corinth. There Mount Cyllene of the ancient Greeks, or Zyria, rises into the air, its flanks covered with dark pines; and farther away still, the Khelmos, or Aroanian Mountain, attains even a more considerable height, its snows descending into a valley on its northern slope, where they give rise to the river Styx, the cold waters of which prove fatal to perjurers, and disappear in a narrow chasm, one of the entrances to Hades. A range of wooded peaks, to the west of the Khelmos, connects that mountain with the Olonos (Mount Erymanthus), celebrated as the haunt of the savage boar destroyed by Hercules. All those mountains, from Corinth as far as Patras, form a rampart running parallel with the southern shore of the gulf, in the direction of which they throw off spurs enclosing steep valleys. In one of these—that of Buraikos—we meet with the grand caverns of Mega-Spileon, which are used as a monastery, and where the most curious structures may be seen built up on every vantage-ground offered by the rocks, suggesting a resemblance to the cells of a vast nest of hornets. The table-land of the Peloponnesus is thus bounded towards the north by an elevated coast range. Another chain of the same kind bounds it on the east. It likewise starts from Mount Cyllene, and extends southward, its various portions being known as Gaurias, Malevo (Mount Artemisium), and Parthenion. It is then broken through by a vast depression, but again rises farther south as the range of Hagios Petros, or Parnon, to the east of Sparta. Getting lower by degrees, it terminates in the promontory of Malea, opposite to the island of Cerigo. It was this cape, tradition tells us, which formed the last refuge of the Centaurs; that is to say, of the barbarian ancestors of the modern Tsakonians. No promontory was more dreaded by Greek navigators than this Cape Malea, owing to sudden gusts of wind, and an ancient proverb says, “When thou hast doubled the cape forget the name of thy native land.”
