Giacomo Casanova, byname Jacques, Chevalier de Seingalt, (born April 2, 1725, Venice [Italy]— died June 4, 1798, Dux, Bohemia [now Duchcov, Czech Republic])
Initiated: 1750 in Lyons, France – Raised: 1750 Paris, France
An ecclesiastic, writer, soldier, spy, and diplomatist, chiefly remembered as the prince of Italian adventurers and as the man who made the name Casanova synonymous with “libertine.” His autobiography, which perhaps exaggerates some of his escapades, is a splendid description of an 18th-century society in the capitals of Europe.
The son of an actor, Casanova was expelled as a young man from the seminary of St. Cyprian for scandalous conduct and launched on a colorful, dissolute career. After a time in the service of a Roman Catholic cardinal, he was a violinist in Venice, joined the Masonic Order (1750) in Lyon, then traveled to Paris, Dresden, Prague, and Vienna. Back in Venice in 1755, Casanova was denounced as a magician and sentenced to five years in the Piombi, prisons under the roof of the Doges’ Palace. On October 31, 1756, he achieved a spectacular escape and made his way to Paris, where he introduced the lottery in 1757 and made a financial reputation and a name for himself among the aristocracy. Wherever he went, Casanova relied on the personal charm to win influence and on gambling and intrigue to support himself.
Fleeing from his creditors in Paris in 1760, he assumed the name Chevalier de Seingalt (which he retained for the rest of his life) and traveled to southern Germany, Switzerland (where he met Voltaire), Savoy, southern France, Florence (whence he was expelled), and Rome. He also spent some time in London. In Berlin (1764) Frederick II offered him a post. Casanova moved on to Riga, St. Petersburg, and Warsaw. A scandal followed by a duel forced him to flee, and he eventually sought refuge in Spain. Permitted to return to Venetian territory between 1774 and 1782, he acted as a spy for the Venetian inquisitors of state. He spent his final years (1785–98) in Bohemia as a librarian for the Count von Waldstein in the château of Dux.
As versatile in his writing as he was in his career, Casanova wrote occasional verse, criticism, a translation of the Iliad (1775), and a satirical pamphlet on the Venetian patriciate, especially the powerful Grimani family. His most important work, however, is his vivid autobiography, first published after his death as Mémoires de J. Casanova de Seingalt, 12 vol. (1826–38). (A definitive edition, based on the original manuscripts, was published in 1960–62 with the title Histoire de ma vie [History of My Life].)
