10. When the sun rises from the eastern ocean, it is shut in by the marshes of the Sea of Azov. On the west it is bounded by the Roman provinces. On the north lie many tribes differing in language and manners; its southern side describes a gentle curve.
11. Over this extended space are dispersed many Greek cities, which have for the most part been founded by the people of Miletus, an Athenian colony, long since established in Asia among the other Ionians by Nileus, the son of the famous Codrus, who is said to have devoted himself to his country in the Doric war.
12. The thin extremities of the bow at each end are commanded by the two Bospori, the Thracian and Cimmerian, placed opposite to one another; and they are called Bospori because through them the daughter of Inachus,[124] who was changed (as the poets relate) into a cow, passed into the Ionian sea.
13. The right curve of the Thracian Bosphorus is covered by a side of Bithynia, formerly called Mygdonia, of which province Thynia and Mariandena are districts; as also is Bebrycia, the inhabitants of which were delivered from the cruelty of Amycus by the valour of Pollux; and also the remote spot in which the soothsayer Phineus was terrified by the threatening flight of the Harpies.
14. The shores are curved into several long bays, into which fall the rivers Sangarius, and Phyllis, and Bizes, and Rebas; and opposite to them at the lower end are the Symplegades, two rocks which rise into abrupt peaks, and which in former times were accustomed to dash against one another with a fearful crash, and then rebounding with a sharp spring, to recoil once more against the object already struck. Even a bird could by no speed of its wings pass between these rocks as they pass and meet again without being crushed to death.
15. These rocks, when the Argo, the first of all ships, hastening to Colchis to carry off the golden fleece, had passed unhurt by them, stood immovable for the future, the power of the whirlwind which used to agitate them being broken; and are now so firmly united that no one who saw them now would believe that they had ever been separated; if all the poems of the ancients did not agree on the point.
16. After this portion of Bithynia, the next provinces are Pontus and Paphlagonia, in which are the noble cities of Heraclea, and Sinope, and Polemonium, and Amisus, and Tios, and Amastris, all originally founded by the energy of the Greeks; and Cerasus, from which Lucullus brought the cherry, and two lofty islands which contain the famous cities of Trapezus and Pityus.
17. Beyond these places is the Acherusian cave, which the natives call Μυχοπόντιον; and the harbour of Acone, and several rivers, the Acheron, the Arcadius, the Iris, the Tibris, and near to that the Parthenius, all of which proceed with a rapid stream into the sea. Close to them is the Thermodon, which rises in Mount Armonius, and flows through the forest of Themiscyra, to which necessity formerly compelled the Amazons to migrate.
18. The Amazons, as may be here explained, after having ravaged their neighbours by bloody inroads, and overpowered them by repeated defeats, began to entertain greater projects; and perceiving their own strength to be superior to their neighbours', and being continually covetous of their possessions, they forced their way through many nations, and attacked the Athenians. But they were routed in a fierce battle, and their flanks being uncovered by cavalry, they all perished.
19. When their destruction became known, the rest, who had been left at home as unwarlike, were reduced to the last extremities; and fearing the attacks of their neighbours, who would now retaliate on them, they removed to the more quiet district of the Thermodon. And after a long time, their posterity again becoming numerous, returned in great force to their native regions, and became in later ages formidable to the people of many nations.
