The personal aspect of Frederick did not correspond to the expectations of those who had formed an ideal from the fame of his talents and the extent of his erudition. His stature was short, his shoulders bent, his form ungainly and corpulent. He was bald and near-sighted. His reddish beard indicated the lineage of the Hohenstaufens. So insignificant was his appearance, that an Arab writer, who saw him at Jerusalem, asserts, with astonishment and contempt, that if he had been exposed for sale as a slave he would not have brought two hundred drachms of silver. The general lustre of his character was marred by many serious and fatal defects. He was tyrannical, perfidious, hypocritical, superstitious, and inordinately dissolute, even in a licentious age. The domestic relations of the greatest of mediæval emperors were the reproach of the Papacy and the horror of Christian Europe. Like the infamous Marquis de Sade, he considered tears and suffering the most desirable prelude to libidinous pleasures. The festivals of the imperial palace of Palermo were enlivened by the performances of the singing- and dancing-girls of the East. European females of the same profession, during the Crusade, travelled in the royal train to Acre, where the novelty of their appearance and costume amused the idle moments of the Moslem princes of Egypt and Syria. Nothing in the career of Frederick provoked the ire of the clergy more than this concession to infidel curiosity. The gigantic Nubians who watched over the Empress, and whose faces were compared to “ancient masks,” awakened the amazement of foreign travellers at the Sicilian court.
