When our ancient brethren, the holy Crusaders, passed through Byzantium on their way to the tomb of the Saviour, the double-headed eagle which they saw embroidered in gold on heavy banners of silk, borne aloft by the Seljuk Turks, had been four thousand years on its way. To these same Crusaders this emblem was an honoured one, and though the enemy displayed it, yet they would fight to death for its possession and in triumph bear it, dripping with blood, to their encampments on the Levantine shore. It was from this Eastern Empire that the knights took this banner to adorn the courts of Charlemagne, and as a sacred relic hung it in the great cathedrals, whose architects and masons had so often been honoured by this Emperor of the West.
