Nunc gelidus sicca Boreas bacchatur ab Arcto;

Nunc Notus adversa praelia fronte gerit.

Tristia, lib. L, Elegia II.

The “blue Symplegades,”—at least what is left of them—to which Byron here refers, are famous for their connection with one of the oldest and most interesting of Greek legends—that of the Argonauts. According to the story which Apollonius of Rhodes has so well developed in his Argonautica, the Symplegades were two floating and ever-clashing rocks, at the junction of the Euxine and the Bosphorus, which were fabled to close upon and crush all ships that attempted to pass between them. When Jason with his fifty-oared ship, the Argos, and his fifty heroes set out for Colchis to fetch back the golden fleece he was obliged to pass between these great colliding rocks. Thanks, however, to the instructions he had received from the seer, Phineus, who had been delivered from the tormenting Harpies by two of the Argonauts, he was able to effect this hitherto impossible passage and to proceed without interruption to his destination.

After this event the eyotlike rocks became fixed in the positions they now occupy. The one, however, on the Asiatic side of the Bosphorus has, owing to the action of the elements, long since disappeared beneath the waves. The other, on the European side, is also rapidly disintegrating, and soon will litter the floor of the sea. But the story of the Argonauts and the Golden Fleece will endure as long as men shall retain a love for the fascinating in myth and legend and the beautiful in art and literature.

Although the Cyanean Islands—as the Symplegades are now called—and the shores of the Euxine are exceptionally rich in places and things of great historic and mythological interest, they are in this respect surpassed by the Bosphorus. Nowhere in the world do myth and legend, traditional associations and historic souvenirs cluster in such numbers and varieties as they do about every rock and bay and promontory of this famous waterway that connects the Euxine with the Sea of Marmora.

Even the names bestowed upon this channel have been manifold. To the ancients it was variously known as the Mouth, the Throat, the Door, and the Key of the Euxine. To-day it is frequently called the Narrows, or the Strait or the Canal of Constantinople. But the appellation which is still the most popular and that by which it is usually designated is that which has its origin in one of the earliest of Greek legends. As expressed in English, the name, which signifies Cow-Ford, or Ox-Ford, seems very prosaic, but the legend on which it is based has always been a favorite with poets and artists.

Io, the beautiful priestess of Hera at Argos, was loved by Zeus and was, in consequence of the jealousy of the goddess, metamorphosed into a heifer. Arriving at the eastern side of the strait, so the fable runs, she plunged into its swiftly-flowing waters and swam to the European shore. And from that time to the present, this famed watercourse has been known the world over as the Bosphorus.

On the promontory of Anadoli Kavak on the Asiatic side of the Bosphorus, we get a view of the site of Hieron which was long regarded as one of the most sacred places in the pagan world. Covered then with gorgeous temples dedicated to the twelve greater gods it ranked as a place of pilgrimage with Delphi and Olympia. The most imposing and sumptuous of these temples was said to have been founded by Jason and consecrated to Zeus Urius, in thanksgiving for the safe return of himself and his fellow Argonauts from their successful expedition to Colchis. Within it stood a priceless statue of Zeus made of ivory and gold, at the base of which was a slab, now preserved in the British Museum, on which were inscribed the words:

The sailor who invokes Zeus Urius that he may enjoy a prosperous voyage either toward the Cyanean Rocks, or on the Ægean sea, itself unsteady and filled with innumerable dangerous shoals scattered here and there, can have a prosperous voyage if first he sacrifices to the god whose statue Philo Antipater has set up, both because of gratitude and to insure favorable augury to sailors.
