Three classes inhabited the city (Alexandria in Egypt): first the Aegyptian or native stock of people, who were quick-tempered and not inclined to civil life; and secondly the mercenary class, who were severe and numerous and intractable...; and, third, the tribe of the Alexandrians, who also were not distinctly inclined to civil life, and for the same reasons, but still they were better than those others, for even though they were a mixed people, still they were Greeks by origin and mindful of the customs common to the Greeks.
