And his Memoirs take one all over Europe, giving sidelights, all the more valuable in being almost accidental, upon many of the affairs and people most interesting to us during two-thirds of the eighteenth century. Giacomo Casanova was born in Venice, of Spanish and Italian parentage, on April 2, 1725; he died at the Chateau of Dux, in Bohemia, on June 4, 1798. In that lifetime of seventy-three years he travelled, as his Memoirs show us, in Italy, France, Germany, Austria, England, Switzerland, Belgium, Russia, Poland, Spain, Holland, Turkey; he met Voltaire at Ferney, Rousseau at Montmorency, Fontenelle, d’Alembert and Crebillon at Paris, George III. in London, Louis XV. at Fontainebleau, Catherine the Great at St. Petersburg, Benedict XII. at Rome, Joseph II. at Vienna, Frederick the Great at Sans-Souci. Imprisoned by the Inquisitors of State in the Piombi at Venice, he made, in 1755, the most famous escape in history. His Memoirs, as we have them, break off abruptly at the moment when he is expecting a safe conduct, and the permission to return to Venice after twenty years’ wanderings. He did return, as we know from documents in the Venetian archives; he returned as secret agent of the Inquisitors, and remained in their service from 1774 until 1782. At the end of 1782 he left Venice; and next year we find him in Paris, where, in 1784, he met Count Waldstein at the Venetian Ambassador’s, and was invited by him to become his librarian at Dux. He accepted, and for the fourteen remaining years of his life lived at Dux, where he wrote his Memoirs.
