Strabo, Geography

Now the distance from the headland that makes the strait only five stadia wide to the harbor which is called “Under the Fig-tree “¹ is thirty-five stadia; and thence to the Horn of the Byzantines,² five stadia. The Horn, which is close to the wall of the Byzantines, is a gulf that extends approximately towards the west for a distance of sixty stadia; it resembles a stag's horn,³ for it is split into numerous gulfs—branches, as it were. The pelamydes⁴ rush into these gulfs and are easily caught—because of their numbers, the force of the current that drives them together, and the narrowness of the gulfs; in fact, because of the narrowness of the area, they are even caught by hand. Now these fish are hatched in the marshes of Lake Maeotis, and when they have gained a little strength they rush out through the mouth of the lake in schools and move along the Asian shore as far as Trapezus and Pharnacia. It is here⁵ that the catching of the fish first takes place, though the catch is not considerable, for the fish have not yet grown to their normal size. But when they reach Sinope, they are mature enough for catching and salting. Yet when once they touch the Cyaneae and pass by these, the creatures take such fright at a certain white rock which projects from the Chalcedonian shore that they forthwith turn to the opposite shore. There they are caught by the current, and since at the same time the region is so formed by nature as to turn the current of the sea there to Byzantium and the Horn at Byzantium, they naturally are driven together thither and thus afford the Byzantines and the Roman people considerable revenue. But the Chalcedonians, though situated near by, on the opposite shore, have no share in this abundance, because the pelamydes do not approach their harbors; hence the saying that Apollo, when the men who founded Byzantium at a time subsequent to the founding of Chalcedon⁶ by the Megarians consulted the oracle, ordered them to “make their settlement opposite the blind,” thus calling the Chalcedonians “blind”, because, although they sailed the regions in question at an earlier time, they failed to take possession of the country on the far side, with all its wealth, and chose the poorer country. I have now carried my description as far as Byzantium, because a famous city, lying as it does very near to the mouth, marked a better-known limit to the coasting-voyage from the Ister. And above Byzantium is situated the tribe of the Astae, in whose territory is a city Calybe,⁷ where Philip the son of Amyntas settled the most villainous people of his kingdom.⁸
