Giacomo Casanova was a brilliant Enlightenment polymath, not just a legendary romantic adventurer.

In short: History remembers Casanova as a frivolous playboy, but he was actually a sophisticated intellectual who befriended Voltaire and Benjamin Franklin. A recently recovered 3,700-page manuscript of his memoirs reveals a man who was a spy, a mathematician, and a science fiction author, far more complex than his popular reputation suggests.

Born in 1725, Giacomo Girolamo Casanova lived a life of extraordinary variety, far exceeding his caricature as a mere seducer. A true Enlightenment polymath, he worked as a musician, cleric, gambler, astrologer, and spy, while also authoring mathematical treatises and a science fiction novel. He even translated The Iliad into his native Venetian dialect. Despite his wide-ranging achievements, he spent his final years in relative obscurity as a librarian at Castle Dux in Bohemia, where he died in 1798 at the age of 73.

The survival of his magnum opus, 'Story of My Life,' is a modern miracle of literary preservation. Hidden in private hands for over two centuries, the 3,700-page manuscript was eventually purchased by the French government in 2010 for $9.6 million, a record for a manuscript sale. Before this, the text had a turbulent history; it was initially published in a heavily censored form in 1821, promptly landing on the Vatican’s Index of Prohibited Books, and was later relegated to 'L’Enfer'—a special cupboard for illicit works—at the National Library in Paris.

Today, scholars are working to rehabilitate Casanova’s legacy, viewing his romantic exploits as merely a narrative device to explore human nature. As curator Corinne Le Bitouzé notes, his command of the French language was revolutionary and alive, reflecting his desire to reach a broad intellectual audience. By digitizing the original manuscript and preparing a new 12-volume edition, researchers are finally moving past the myth of the 'frivolous sexual adventurer' to reveal a man who was, in truth, a central figure of 18th-century European culture.

The recent scholarly focus on Casanova highlights a shift in how we perceive historical figures once dismissed as mere gadabouts. Whether he was hobnobbing with Catherine the Great or debating with Voltaire, Casanova remained a dedicated observer of his time. His memoir, once considered a scandalous relic, is now recognized as a 'national treasure' in France, proving that even the most misunderstood lives can eventually find their place in the canon of serious literature.
