On the _European_ Shore there is a Tower, called _Pharos_, where they hang out Lights in the Night, to guide Sailors by. Not far from this Place, a River falls into the Sea, in the Channel whereof there are found Stones, little inferior to _Onyxes_ or _Sardonyxes_, and, if they be polished, are as shining as they. A few Miles from that Bay, which I lately spoke of, we may see those Streights over which _Darius_ wasted his Army against the _European Scythians_: And about the Middle, between the two Mouths of the _Bosphorus_, there are two Castles, one of which is in _Europe_, and the other on the opposite Shore, in _Asia_. This latter was possessed by the _Turks_ long before _Mahomet_ took _Constantinople_. The other was built by him some few Years after he became Master of that City. The _Turks_ make use of it, at this Day, as a Prison for the nobler Sort of their Captives. _Lazarus_, a Commander, or Prince of the _Epitots_ not long ago was taken Prisoner by the _Turks_, together with some _Spaniards_ at _Castlenovo_, and committed to this Tower; from whence making his Escape, and being retaken, he was impal’d, (_i. e._) put to a most cruel Death, by having a Pole thrust thro’ his Body, from his Fundament to his very Neck; yet he indured it with incredible Patience. Perhaps you expect that I should here give you an Account of those floating Islands, called _Cyaneæ_ or _Symplegades_. But, to deal freely with you, those few Hours that I spent on the _Pontus_, I saw no such Islands at all; whether they had been carried to any other Place, I know not: If you desire to have a more particular Information concerning them, you may consult _Peter Gyllius_, who was an exact Enquirer into such Curiosities; for my Part, I shall record only what I saw, or know to be true. Yet I think it is not fit for me to conceal a Mistake that _Polybius_ is guilty of; for he proposes many Arguments, to prove that, in Tract of Time, the _Euxine_ will be choaked up with Sand and other Trash, brought in by the _Danow_, the _Borysthenes_, and other great Rivers falling into it, that it would be made unfit for Navigation; whereas, the contrary appeared to me; for that Sea is every jot as navigable, at this Day, as it was of old in the Days of _Polybius_. And though he seemed to have some Grounds for his Opinion, that to him were irrefragable, yet Time hath shewed them to be weak. The like Observation holds in other Cases; for, of old, who would not believe the Ancients, who affirmed, upon seemingly imaginable Grounds, That the Torrid Zone was inhabitable? whereas, later Discoveries have fully convinced us, That those hot Countries are as well inhabited as any other Part of the Terrestial Globe; nay, when the Sun is at the highest with them, and darts down its Rays perpendicularly upon them; even at that very Time the Ardency of the Heat is so tempered and cooled by continued Rains, that those Countries are rendered very fit for human Habitations. But to return.
