An isthmus connects the peninsula with the mainland. Immediately on the landward, that is, eastern side of the isthmus, the massive and imposing rock of Palamidi, one of the strongest fortresses in Greece, towers up abruptly to a height of over seven hundred feet. The fortifications which crown its summit were built by the Venetians and Turks; they now serve as a prison. In their walls, as well as in the walls of Itsh-Kaleh, are built many Venetian inscriptions, some of them bearing the lion of St. Mark. Three sides of the mighty rock are precipitous, but on the south-eastern side it is accessible, being joined by a ridge to the hills. The ascent from Nauplia is by a long staircase at the north-western corner of the fortress; it begins close to the gate of the town. The name Palamidi is derived from Palamedes, the son of Nauplius. Palamedium was probably the ancient name of the fortress, though no classical writer mentions it. The prospect from the summit over the gulf and plain of Argos, with the background of mountains encircling the plain, is very fine. Nor is the view from the quay of Nauplia across the bay to the mountains of Argolis one to be easily forgotten, especially if seen by moonlight, when the sea is calm, the stars are shining, and the tall yard-arms of the lateen-rigged craft stand out like black wings against the sky, now blotting out and now disclosing a star as the boats heave on the gentle swell.
XXXIII. THE SPRINGS OF THE ERASINUS.—From Argos the road to Tegea goes south-west. At first it skirts the foot of the steep Larisa, and then runs through the southern part of the Argolic plain. On the right rise the mountains, of no great height, which bound the plain on the west. About three miles from Argos we quit the highway and strike westward towards the hills through a beautiful avenue of fine silver poplars, plane-trees, and oleanders. It soon brings us to the springs.
The spot is very picturesque. A rugged mountain here descends in precipices of yellowish limestone to the plain, and at its foot a body of clear sparkling water comes rushing impetuously in several streams from the rocks, partly issuing from a low cavern, partly welling up from the ground. Under the rocks the water forms a pellucid but shallow pool, where water-plants of a vivid green grow thickly; then flowing through the arches of a wall, which partially dams up the pool, it is diverted into several channels shaded by tall poplars, willows, and mulberries, and so turns in a short space a dozen mills—the Mills of Argos, as they are called. After watering the rice-fields, the channels unite once more into a river, which finds its way into the sea through swampy ground, among thick tangled beds of reeds and sedge, some three miles only from its source at the foot of the hills. This river, the modern Kephalari, is the Erasinus (‘the lovely river’) of antiquity. It is the only river of the Argolic plain which flows summer and winter alike; and the opinion both of the ancient and the modern Greeks that it is an outlet of the Stymphalian lake in Arcadia appears to be well founded.
