It was indeed on that very narrow strait which parts Europe from Asia, at Europe's furthest extremity, that the Greeks built Byzantium. When they consulted the Pythian Apollo as to where they should found a city, the oracle replied that they were to seek a home opposite to the blind men's country. This obscure hint pointed to the people of Chalcedon, who, though they arrived there first and saw before others the advantageous position, chose the worse. For Byzantium has a fruitful soil and productive seas, as immense shoals of fish pour out of the Pontus and are driven by the sloping surface of the rocks under water to quit the windings of the Asiatic shore and take refuge in these harbours. Consequently the inhabitants were at first money-making and wealthy traders, but afterwards, under the pressure of excessive burdens, they petitioned for immunity or at least relief, and were supported by the emperor, who argued to the Senate that, exhausted as they were by the late wars in Thrace and Bosporus, they deserved help. So their tribute was remitted for five years.
