Yet through Alexander (the Great) Bactria and the Caucasus learned to revere the gods of the Greeks … Alexander established more than seventy cities among savage tribes, and sowed all Asia with Greek magistracies … Egypt would not have its Alexandria, nor Mesopotamia its Seleucia, nor Sogdiana its Prophthasia, nor India its Bucephalia, nor the Caucasus a Greek city, for by the founding of cities in these places savagery was extinguished and the worse element, gaining familiarity with the better, changed under its influence.
