“This Frederick reigned thirty years as Emperor, and was a man of great mark and great worth, learned in letters and of natural ability, universal in all things; he knew the Latin language, the Italian, the German, French, Greek, and Arabic; was copiously endowed with all virtues, liberal and courteous in giving, valiant and skilled in arms, and was much feared. And he was dissolute and voluptuous in many ways, and had many concubines and mamelukes, after the Saracenic fashion; he was addicted to all sensual delights, and led an Epicurean life, taking no account of any other; and this was one principal reason why he was an enemy to the clergy and the Holy Church.”
