And first Orpheus spoke, and warned them:  “We shall come now to the wandering blue rocks; my mother warned me of them, Calliope, the immortal muse.”

And soon they saw the blue rocks shining, like spires and castles of gray glass, while an ice-cold wind blew from them, and chilled all the heroes’ hearts.  And as they neared, they could see them heaving, as they rolled upon the long sea waves, crashing and grinding together, till the roar went up to heaven.  The sea sprang up in spouts between them, and swept round them in white sheets of foam; but their heads swung nodding high in air, while the wind whistled shrill among the crags.

The heroes’ hearts sank within them, and they lay upon their oars in fear; but Orpheus called to Tiphys the helmsman:  “Between them we must pass; so look ahead for an opening, and be brave, for Hera is with us.”  But Tiphys the cunning helmsman stood silent, clenching his teeth, till he saw a heron come flying mast high toward the rocks, and hover awhile before them, as if looking for a passage through.  Then he cried, “Hera has sent us a pilot; let us follow the cunning bird.”

Then the heron flapped to and fro a moment, till he saw a hidden gap, and into it he rushed like an arrow, while the heroes watched what would befall.

And the blue rocks clashed together as the bird fled swiftly through; but they struck but a feather from his tail, and then rebounded apart at the shock.

Then Tiphys cheered the heroes, and they shouted; and the oars bent like withes beneath their strokes, as they rushed between those toppling ice crags, and the cold blue lips of death.  And ere the rocks could meet again they had passed them, and were safe out in the open sea.

And after that they sailed on wearily along the Asian coast, by the Black Cape and Thyneis, where the hot stream of Thymbris falls into the sea, and Sangarius, whose waters float on the Euxine, till they came to Wolf the river, and to Wolf the kindly king.  And there died two brave heroes, Idmon and Tiphys the wise helmsman; one died of an evil sickness, and one a wild boar slew.  So the heroes heaped a mound above them, and set upon it an oar on high, and left them there to sleep together, on the far-off Lycian shore.  But Idas killed the boar, and avenged Tiphys; and Ancaios took the rudder and was helmsman, and steered them on toward the east.

And they went on past Sinope, and many a mighty river’s mouth, and past many a barbarous tribe, and the cities of the Amazons, the warlike women of the East, till all night they heard the clank of anvils and the roar of furnace blasts, and the forge fires shone like sparks through the darkness, in the mountain glens aloft; for they were come to the shores of the Chalybes, the smiths who never tire, but serve Ares the cruel War god, forging weapons day and night.

And at day dawn they looked eastward, and midway between the sea and the sky they saw white snow peaks hanging glittering sharp and bright above the clouds.  And they knew that they were come to Caucasus, at the end of all the earth; Caucasus the highest of all mountains, the father of the rivers of the East.  On his peak lies chained the Titan, while a vulture tears his heart; and at his feet are piled dark forests round the magic Colchian land.
