It is indeed a new experience to read this history of a man who, refraining from nothing, has concealed nothing; of one who stood in the courts of Louis the Magnificent before Madame de Pompadour and the nobles of the Ancien Regime, and had an affair with an adventuress of Denmark Street, Soho; who was bound over to keep the peace by Fielding, and knew Cagliostro. The friend of popes and kings and noblemen, and of all the male and female ruffians and vagabonds of Europe, abbe, soldier, charlatan, gamester, financier, diplomatist, viveur, philosopher, virtuoso, chemist, fiddler, and buffoon, each of these, and all of these was Giacomo Casanova, Chevalier de Seingalt, Knight of the Golden Spur.
