But unlike Delphi and Olympia where there is still, thanks to the labors of French and German archæologists, very much to remind one of the past grandeur of these historic places, “not a stone upon a stone” remains on the site of Hieron to attest to its former splendor and majesty. As in so many other parts of the world, the temples of Hieron served as quarries for peoples of a later age who knew not the gods of Olympus, or who had a special interest in consigning them to oblivion. And where, in days of yore, the clouds of incense and the smoke of sacrifice, in the most superb of temples stimulated the fervor of vast multitudes from far distant lands, the traveler to-day finds nothing of the pristine glory of Hieron except what nature gave it—its superb site and its enchanting vistas of the Bosphorus and the Euxine.

After the fall of paganism, Hieron had many vicissitudes. Having been converted into one of the strongest fortresses on the Bosphorus, it was time and again singled out for attack by the enemies of the Byzantine Empire. Among the most celebrated of them was Harun-al-Rashid who led an army the whole way from Bagdad with a view of effecting the conquest of Constantinople and with it of the Byzantine Empire. At a later date Hieron and the stronghold on the opposite side of the Strait fell into the hands of the Genoese. Not long afterwards it was captured by the Sultan Bayazid I, “the Thunderbolt,” and since then it has been in the possession of the Turks.

A short distance to the southwest, on the European shore, is a beautiful valley where the Crusaders are said to have encamped on their way to the Holy Land. A colossal plane tree is here seen which bears the name of “Plane tree of Godfrey of Bouillon,” from a tradition that it was planted by this famous hero of the Christian host.

At Roumeli Hissar, we reach the narrowest point of the Bosphorus and one which is most rich in historical associations. According to tradition, it was here that Xenophon and his immortal Ten Thousand crossed over into Europe after their famous retreat from the heart of Babylonia—a retreat which, revealing, as it did, the military weakness of the Persian Colossus, paved the way for the victories of the Granicus, the Issus, and Arbela and for the conquest of Asia by Alexander the Great.

Here, too, it was that Mandrocles of Samos constructed the bridge of boats that enabled the vast Persian army under Darius to cross into Europe at the time of that monarch’s disastrous campaign against the Scythians. Mandrocles was so elated by his achievement that he had it commemorated in the temple of Hera, in his native Samos, by a picture with the inscription:

The fish-fraught Bosphorus bridged, to Juno’s fane

Did Mandrocles this proud memorial bring;

When for himself a crown he’d skill to gain,

For Samos praise, contenting the Great King.

But a large volume would be required to give even a brief notice of the countless myths, legends, traditions, and historical souvenirs which cluster about the shores of the Bosphorus from the Euxine to the Golden Horn. They have been the scenes of tragedies and romances and intrigues without number. From the dawn of history the Bosphorus has been constantly a bone of contention among rival and conflicting interests and an important factor in many of the great wars that have convulsed Asia and Europe. And until a plan shall be elaborated for eliminating international jealousies and harmonizing the antagonistic policies and aspirations of many peoples of divers races and creeds, it is not probable that the future history of this unique waterway will be materially different from that of the past. Altruism among nations has so far been confined to words and, from present indications, the day is far distant when it will be revealed in deeds.
