“And now they reach’d the running rivulets clear, Where from Scamander’s dizzy flood arise Two fountains, tepid one, from which a smoke Issues voluminous as from a fire, The other, even in summer heats, like hail For cold, or snow, or crystal stream frost-bound:”[370] this writer tells us we must not be surprised, that although the cold spring still remains, the hot cannot be discovered; and says we must reckon the failing of the hot spring as the cause. He goes on to relate certain catastrophes recorded by Democles, how formerly in the reign of Tantalus[371] there were great earthquakes in Lydia and Ionia as far as the Troad,[372] which swallowed up whole villages and overturned Mount Sipylus;[373] marshes then became lakes, and the city of Troy was covered by the waters.[374] Pharos, near Egypt, which anciently was an island, may now be called a peninsula, and the same may be said of Tyre and Clazomenæ.[375] During my stay at Alexandria in Egypt the sea rose so high near Pelusium[376] and Mount Casius[377] as to overflow the land, and convert the mountain into an island, so that a journey from Casius into Phœnicia might have been undertaken by water. We should not be surprised therefore if in time to come the isthmus[378] which separates the Egyptian sea[379] from the Erythræan,[380] should part asunder or subside, and becoming a strait, connect the outer and inner seas,[381] similarly to what has taken place at the strait of the Pillars.

The Piræus having been formerly an island, and lying πέραν, or off the shore, is said to have thus received its name. Leucas,[382] on the contrary, has been made an island by the Corinthians, who cut through the isthmus which connected it with the shore [of the mainland]. It is concerning this place that Laertes is made to say, “Oh that I possess’d Such vigour now as when in arms I took Nericus, continental city fair.”[383]
