Hi there, Wikipedia English - The Free Encyclopedia says: Giacomo Casanova Giovanni Giacomo Casanova (April 2, 1725 – June 4, 1798) was a Venetian adventurer, author, and philanderer. His autobiography, Histoire de ma vie (Story of My Life), is regarded as one of the most authentic sources of the customs and norms of European social life during the 18th century. So famous a womanizer was the Italian-born libertine Giacomo Casanova that, a full two centuries after his death, his name remains synonymous with the art of seduction. But for the years he spent in the employ of Count Waldstein of Bohemia as a librarian, Casanova, "the world's greatest lover" — a one-time consort of European royalty, popes and cardinals, and man known to the likes of Voltaire, Goethe and Mozart — would have been consigned to obscurity. As it was, he barely found the peace to write his memoirs.
