" The terrible example of the work wrought by the Arabs," says Bikelas, "in this instance is a sufficient proof of how great was the danger from which not only the Hellenic world of the East in particular, but also Christian Europe in general was saved by the efforts of the Byzan- tine emperors." The power of the caliphs, however, was broken ; they gave way to a new mortal foe of Christianity — that new enemy was the Turk.
