Giacomo Girolamo Casanova was born in
Venice in 1725 to actress
Zanetta Farussi, wife of actor and dancer
Gaetano Casanova. Giacomo was the first of six children, being followed by
Francesco Giuseppe (1727–1803),
Giovanni Battista (1730–1795), Faustina Maddalena (1731–1736), Maria Maddalena Antonia Stella (1732–1800), and Gaetano Alvise (1734–1783).
At the time of Casanova's birth, the city of Venice thrived as the pleasure capital of Europe, ruled by political and religious conservatives who tolerated social vices and encouraged tourism. It was a required stop on the
Grand Tour, traveled by young men coming of age, especially Englishmen. The famed
Carnival, gambling houses, and beautiful
courtesans were powerful drawing cards. This was the milieu that bred Casanova and made him its most famous and representative citizen.
San Samuele - Casanova's childhood neighborhood.
Casanova was cared for by his grandmother Marzia Baldissera while his mother toured about Europe in the theater. His father died when he was eight. As a child, Casanova suffered nosebleeds, and his grandmother sought help from a witch: "Leaving the gondola, we enter a hovel, where we find an old woman sitting on a pallet, with a black cat in her arms and five or six others around her."
 Though the
unguent applied was ineffective, Casanova was fascinated by the incantation.
 Perhaps to remedy the nosebleeds (a physician blamed the density of Venice's air), Casanova, on his ninth birthday, was sent to a boarding house on the mainland in
Padua. For Casanova, the neglect by his parents was a bitter memory. "So they got rid of me," he proclaimed.
Conditions at the boarding house were appalling, so he appealed to be placed under the care of Abbé Gozzi, his primary instructor, who tutored him in academic subjects as well as the violin. Casanova moved in with the priest and his family and lived there through most of his teenage years.
 It was also in the Gozzi household that Casanova first came into contact with the opposite sex, when Gozzi's younger sister Bettina fondled him at the age of eleven. Bettina was "pretty, lighthearted, and a great reader of romances. ... The girl pleased me at once, though I had no idea why. It was she who little by little kindled in my heart the first sparks of a feeling which later became my ruling passion."
 Although she subsequently married, Casanova maintained a lifelong attachment to Bettina and the Gozzi family.
Early on, Casanova demonstrated a quick wit, an intense appetite for knowledge, and a perpetually inquisitive mind. He entered the
University of Padua at twelve and graduated at seventeen, in 1742, with a degree in law ("for which I felt an unconquerable aversion").
 It was his guardian's hope that he would become an ecclesiastical lawyer.
 Casanova had also studied moral philosophy, chemistry, and mathematics, and was keenly interested in medicine. ("I should have been allowed to do as I wished and become a physician, in which profession quackery is even more effective than it is in legal practice."
) He frequently prescribed his own treatments for himself and friends.
 While attending the university, Casanova began to gamble and quickly got into debt, causing his recall to Venice by his grandmother, but the gambling habit became firmly established.
Palazzo Malipiero c. 1716
Back in Venice, Casanova started his clerical law career and was admitted as an
abbé after being conferred minor orders by the
Patriarch of Venice. He shuttled back and forth to Padua to continue his university studies. By now, he had become something of a dandy—tall and dark, his long hair powdered, scented, and elaborately curled.
 He quickly ingratiated himself with a patron (something he was to do all his life), 76-year-old Venetian senator Alvise Gasparo Malipiero, the owner of
Palazzo Malipiero, close to Casanova's home in Venice.
 Malipiero moved in the best circles and taught young Casanova a great deal about good food and wine, and how to behave in society. However, Casanova was caught dallying with Malipiero's intended object of seduction, actress Teresa Imer, and the senator drove both of them from his house.
 Casanova's growing curiosity about women led to his first complete sexual experience, with two sisters, Nanetta and Marton Savorgnan, then fourteen and sixteen, who were distant relatives of the
Grimanis. Casanova proclaimed that his life avocation was firmly established by this encounter.
Early career in Italy and abroad
Scandals tainted Casanova's short church career. After his grandmother's death, Casanova entered a seminary for a short while, but soon his indebtedness landed him in prison for the first time. An attempt by his mother to secure him a position with bishop Bernardo de Bernardis was rejected by Casanova after a very brief trial of conditions in the bishop's
 Instead, he found employment as a scribe with the powerful Cardinal Acquaviva in
Rome. On meeting the
pope, Casanova boldly asked for a dispensation to read the "forbidden books" and from eating fish (which he claimed inflamed his eyes). He also composed love letters for another cardinal. But when Casanova became the scapegoat for a scandal involving a local pair of star-crossed lovers, Cardinal Acquaviva dismissed Casanova, thanking him for his sacrifice, but effectively ending his church career.
In search of a new profession, Casanova bought a commission to become a military officer for the
Republic of Venice. His first step was to look the part:
Reflecting that there was now little likelihood of my achieving fortune in my ecclesiastical career, I decided to dress as a soldier ... I inquire for a good tailor ... he brings me everything I need to impersonate a follower of Mars. ... My uniform was white, with a blue vest, a shoulder knot of silver and gold... I bought a long sword, and with my handsome cane in hand, a trim hat with a black cockade, with my hair cut in side whiskers and a long false pigtail, I set forth to impress the whole city.
He joined a Venetian regiment at
Corfu, his stay being broken by a brief trip to
Constantinople, ostensibly to deliver a letter from his former master the Cardinal.
 He found his advancement too slow and his duty boring, and he managed to lose most of his pay playing
faro. Casanova soon abandoned his military career and returned to Venice.
At the age of 21, he set out to become a professional gambler, but losing all the money remaining from the sale of his commission, he turned to his old benefactor Alvise Grimani for a job. Casanova thus began his third career, as a violinist in the
San Samuele theater, "a menial journeyman of a sublime art in which, if he who excels is admired, the mediocrity is rightly despised. ... My profession was not a noble one, but I did not care. Calling everything prejudice, I soon acquired all the habits of my degraded fellow musicians."
 He and some of his fellows, "often spent our nights roaming through different quarters of the city, thinking up the most scandalous practical jokes and putting them into execution ... we amused ourselves by untying the gondolas moored before private homes, which then drifted with the current". They also sent midwives and physicians on false calls.
Good fortune came to the rescue when Casanova, unhappy with his lot as a musician, saved the life of a Venetian nobleman of the Bragadin family, who had a stroke while riding with Casanova in a gondola after a wedding ball. They immediately stopped to have the senator bled. Then, at the senator's palace, a physician bled the senator again and applied an ointment of
mercury to the senator's chest (mercury was an all-purpose but toxic remedy of the time). The mercury raised his temperature and induced a massive fever, and Bragadin appeared to be choking on his own swollen
windpipe. A priest was called as death seemed to be approaching. However, despite protests from the attending physician, Casanova ordered the removal of the ointment and the washing of the senator's chest with cool water. The senator recovered from his illness with rest and a sensible diet.
 Because of his youth and his facile recitation of medical knowledge, the senator and his two bachelor friends thought Casanova wise beyond his years, and concluded that he must be in possession of occult knowledge. As they were
cabalists themselves, the senator invited Casanova into his household and became a lifelong patron.
Casanova stated in his memoirs:
I took the most creditable, the noblest, and the only natural course. I decided to put myself in a position where I need no longer go without the necessities of life: and what those necessities were for me no one could judge better than me.... No one in Venice could understand how an intimacy could exist between myself and three men of their character, they all heaven and I all earth; they most severe in their morals, and I addicted to every kind of dissolute living.
For the next three years under the senator's patronage, working nominally as a legal assistant, Casanova led the life of a nobleman, dressing magnificently and, as was natural to him, spending most of his time gambling and engaging in amorous pursuits.
 His patron was exceedingly tolerant, but he warned Casanova that some day he would pay the price; "I made a joke of his dire Prophecies and went my way." However, not much later, Casanova was forced to leave Venice, due to further scandals. Casanova had dug up a freshly buried corpse in order to play a practical joke on an enemy and exact revenge—but the victim went into a paralysis, never to recover. And in another scandal, a young girl who had duped him accused him of rape and went to the officials.
 Casanova was later acquitted of this crime for lack of evidence, but by this time he had already fled from Venice.
Parma, Casanova entered into a three-month affair with a Frenchwoman he named "Henriette", perhaps the deepest love he ever experienced—a woman who combined beauty, intelligence, and culture. In his words, "They who believe that a woman is incapable of making a man equally happy all the twenty-four hours of the day have never known an Henriette. The joy which flooded my soul was far greater when I conversed with her during the day than when I held her in my arms at night. Having read a great deal and having natural taste, Henriette judged rightly of everything."
 She also judged Casanova astutely. As noted Casanovist J. Rives Childs wrote:
Perhaps no woman so captivated Casanova as Henriette; few women obtained so deep an understanding of him. She penetrated his outward shell early in their relationship, resisting the temptation to unite her destiny with his. She came to discern his volatile nature, his lack of social background, and the precariousness of his finances. Before leaving, she slipped into his pocket five hundred louis, mark of her evaluation of him.
Crestfallen and despondent, Casanova returned to Venice, and after a good gambling streak, he recovered and set off on a
Grand Tour, reaching Paris in 1750.
 Along the way, from one town to another, he got into sexual escapades resembling operatic plots.
 In Lyon, he entered the society of
Freemasonry, which appealed to his interest in secret rites and which, for the most part, attracted men of intellect and influence who proved useful in his life, providing valuable contacts and uncensored knowledge. Casanova was also attracted to
Casanova stayed in Paris for two years, learned the language, spent much time at the theater, and introduced himself to notables. Soon, however, his numerous liaisons were noted by the Paris police, as they were in nearly every city he visited.
In 1752, he and his brother Francesco moved from Paris to
Dresden, where his mother and sister Maria Maddalena were living. His new play, La Moluccheide, now lost, was performed at the Royal Theatre, where his mother often played in lead roles.
 He then visited
Vienna, where the tighter moral atmosphere of the latter city was not to his liking. He finally returned to Venice in 1753.
 In Venice, Casanova resumed his escapades, picking up many enemies and gaining the greater attention of the Venetian inquisitors. His police record became a lengthening list of reported blasphemies, seductions, fights, and public controversy.
 A state spy, Giovanni Manucci, was employed to draw out Casanova's knowledge of cabalism and Freemasonry and to examine his library for forbidden books. Senator Bragadin, in total seriousness this time (being a former inquisitor himself), advised his "son" to leave immediately or face the stiffest consequences.
Imprisonment and escape
On 26 July 1755, at age thirty, Casanova was arrested for affront to religion and common decency:
 "The Tribunal, having taken cognizance of the grave faults committed by G. Casanova primarily in public outrages against the holy religion, their Excellencies have caused him to be arrested and imprisoned under the Leads."
The Leads" was a prison of seven cells on the top floor of the east wing of the
Doge's palace, reserved for prisoners of higher status as well as certain types of offenders—such as political prisoners, defrocked or libertine priests or monks, and usurers—and named for the lead plates covering the palace roof. The following 12 September, without a trial and without being informed of the reasons for his arrest and of the sentence, he was sentenced to five years imprisonment.,
"It's him. Place him in custody!"
He was placed in solitary confinement with clothing, a pallet bed, table and armchair in "the worst of all the cells",
 where he suffered greatly from the darkness, summer heat and "millions of fleas". He was soon housed with a series of cell mates, and after five months and a personal appeal from Count Bragadin was given warm winter bedding and a monthly stipend for books and better food. During exercise walks he was granted in the prison garret, he found a piece of black marble and an iron bar which he smuggled back to his cell; he hid the bar inside his armchair. When he was temporarily without cell mates, he spent two weeks sharpening the bar into a spike on the stone. Then he began to gouge through the wooden floor underneath his bed, knowing that his cell was directly above the Inquisitor's chamber.
 Just three days before his intended escape, during a festival when no officials would be in the chamber below, Casanova was moved to a larger, lighter cell with a view, despite his protests that he was perfectly happy where he was. In his new cell, "I sat in my armchair like a man in a stupor; motionless as a statue, I saw that I had wasted all the efforts I had made, and I could not repent of them. I felt that I had nothing to hope for, and the only relief left to me was not to think of the future."
Overcoming his inertia, Casanova set upon another escape plan. He solicited the help of the prisoner in the adjacent cell, Father Balbi, a renegade priest. The spike, carried to the new cell inside the armchair, was passed to the priest in a folio Bible carried under a heaping plate of pasta by the hoodwinked jailer. The priest made a hole in his ceiling, climbed across and made a hole in the ceiling of Casanova's cell. To neutralize his new cell mate, who was a spy, Casanova played on his superstitions and terrorized him into silence.
 When Balbi broke through to Casanova's cell, Casanova lifted himself through the ceiling, leaving behind a note that quoted the 117th Psalm (Vulgate): "I shall not die, but live, and declare the works of the Lord".
Illustration from Story of My Flight
The spy remained behind, too frightened of the consequences if he were caught escaping with the others. Casanova and Balbi pried their way through the lead plates and onto the sloping roof of the Doge's Palace, with a heavy fog swirling. The drop to the nearby canal being too great, Casanova prised open the grate over a dormer window, and broke the window to gain entry. They found a long ladder on the roof, and with the additional use of a bedsheet "rope" that Casanova had prepared, lowered themselves into the room whose floor was twenty-five feet below. They rested until morning, changed clothes, then broke a small lock on an exit door and passed into a palace corridor, through galleries and chambers, and down stairs, where by convincing the guard they had inadvertently been locked into the palace after an official function, they left through a final door.
 It was six in the morning and they escaped by gondola. Eventually, Casanova reached Paris, where he arrived on the same day (January 5, 1757) that
Robert-François Damiens made an attempt on the life of
 (Casanova would later
witness and describe his execution.)
Thirty years later in 1787, Casanova wrote Story of My Flight, which was very popular and was reprinted in many languages, and he repeated the tale a little later in his memoirs.
 Casanova's judgment of the exploit is characteristic:
Thus did God provide me with what I needed for an escape which was to be a wonder if not a miracle. I admit that I am proud of it; but my pride does not come from my having succeeded, for luck had a good deal to do with that; it comes from my having concluded that the thing could be done and having had the courage to undertake it.
Return to Paris
He knew his stay in Paris might be a long one and he proceeded accordingly: "I saw that to accomplish anything I must bring all my physical and moral faculties in play, make the acquaintance of the great and the powerful, exercise strict self-control, and play the chameleon."
 Casanova had matured, and this time in Paris, though still depending at times on quick thinking and decisive action, he was more calculating and deliberate. His first task was to find a new patron. He reconnected with old friend
de Bernis, now the
Foreign Minister of France. Casanova was advised by his patron to find a means of raising funds for the state as a way to gain instant favor. Casanova promptly became one of the trustees of the first state
lottery, and one of its best ticket salesmen. The enterprise earned him a large fortune quickly.
 With money in hand, he traveled in high circles and undertook new seductions. He duped many socialites with his occultism, particularly the Marquise
Jeanne d'Urfé, using his excellent memory which made him appear to have a sorcerer's power of
numerology. In Casanova's view, "deceiving a fool is an exploit worthy of an intelligent man".
Casanova claimed to be a
Rosicrucian and an
alchemist, aptitudes which made him popular with some of the most prominent figures of the era, among them
Madame de Pompadour,
Count de Saint-Germain,
Jean-Jacques Rousseau. So popular was alchemy among the nobles, particularly the search for the "
philosopher's stone", that Casanova was highly sought after for his supposed knowledge, and he profited handsomely.
 He met his match, however, in the Count de Saint-Germain: "This very singular man, born to be the most barefaced of all imposters, declared with impunity, with a casual air, that he was three hundred years old, that he possessed the universal medicine, that he made anything he liked from nature, that he created diamonds."
De Bernis decided to send Casanova to
Dunkirk on his first spying mission. Casanova was paid well for his quick work and this experience prompted one of his few remarks against the
ancien régime and the class he was dependent on. He remarked in hindsight, "All the French ministers are the same. They lavished money which came out of the other people's pockets to enrich their creatures, and they were absolute: The down-trodden people counted for nothing, and, through this, the indebtedness of the State and the confusion of finances were the inevitable results. A Revolution was necessary."
Seven Years' War began, Casanova was again called to help increase the state treasury. He was entrusted with a mission of selling
state bonds in
Amsterdam, Holland being the financial center of Europe at the time.
 He succeeded in selling the bonds at only an 8% discount, and the following year was rich enough to found a silk manufactory with his earnings. The French government even offered him a title and a pension if he would become a French citizen and work on behalf of the Finance Ministry, but he declined, perhaps because it would frustrate his Wanderlust.
 Casanova had reached his peak of fortune but could not sustain it. He ran the business poorly, borrowed heavily trying to save it, and spent much of his wealth on constant liaisons with his female workers who were his "
For his debts, Casanova was imprisoned again, this time at
For-l'Évêque, but was liberated four days afterwards, upon the insistence of the
Marquise d'Urfé. Unfortunately, though he was released, his patron de Bernis was dismissed by
Louis XV at that time and Casanova's enemies closed in on him. He sold the rest of his belongings and secured another mission to Holland to distance himself from his troubles.
On the run
This time, however, his mission failed and he fled to
Stuttgart in the spring of 1760, where he lost the rest of his fortune. He was yet again arrested for his debts, but managed to escape to
Switzerland. Weary of his wanton life, Casanova visited the monastery of
Einsiedeln and considered the simple, scholarly life of a monk. He returned to his hotel to think on the decision only to encounter a new object of desire, and reverting to his old instincts, all thoughts of a monk's life were quickly forgotten.
 Moving on, he visited
Albrecht von Haller and
Voltaire, and arrived in
Turin, moving from one sexual romp to another.
In 1760, Casanova started styling himself the
Chevalier de Seingalt, a name he would increasingly use for the rest of his life. On occasion, he would also call himself Count de Farussi (using his mother's maiden name) and when
Pope Clement XIII presented Casanova with the
Papal Order of the
Éperon d'or, he had an impressive cross and ribbon to display on his chest.
Back in Paris, he set about one of his most outrageous schemes—convincing his old dupe the Marquise d'Urfé that he could turn her into a young man through occult means. The plan did not yield Casanova the big payoff he had hoped for, and the Marquise d'Urfé finally lost faith in him.
Casanova traveled to England in 1763, hoping to sell his idea of a state lottery to English officials. He wrote of the English, "the people have a special character, common to the whole nation, which makes them think they are superior to everyone else. It is a belief shared by all nations, each thinking itself the best. And they are all right."
 Through his connections, he worked his way up to an audience with King George III, using most of the valuables he had stolen from the Marquise d'Urfé. While working the political angles, he also spent much time in the bedroom, as was his habit. As a means to find females for his pleasure, not being able to speak English, he put an advertisement in the newspaper to let an apartment to the "right" person. He interviewed many young women, choosing one "Mistress Pauline" who suited him well. Soon, he established himself in her apartment and seduced her. These and other liaisons, however, left him weak with
venereal disease and he left England broke and ill.
He went on to the Austrian Netherlands, recovered, and then for the next three years, traveled all over Europe, covering about 4,500 miles by coach over rough roads, and going as far as
Moscow and St Petersburg (the average daily coach trip being about 30 miles). Again, his principal goal was to sell his lottery scheme to other governments and repeat the great success he had with the French government. But a meeting with
Frederick the Great bore no fruit and in the surrounding German lands, the same result. Not lacking either connections or confidence, Casanova went to Russia and met with
Catherine the Great but she flatly turned down the lottery idea.
In 1766, he was expelled from
Warsaw following a pistol duel with Colonel
Franciszek Ksawery Branicki over an Italian actress, a lady friend of theirs. Both duelists were wounded, Casanova on the left hand. The hand recovered on its own, after Casanova refused the recommendation of doctors that it be amputated.
 From Warsaw, he traveled to
Breslau in the
Kingdom of Prussia, then to Dresden, where he contracted yet another venereal infection.
 He returned to Paris for several months in 1767 and hit the gambling salons, only to be expelled from France by order of Louis XV himself, primarily for Casanova's scam involving the Marquise d'Urfé.
 Now known across Europe for his reckless behavior, Casanova would have difficulty overcoming his notoriety and gaining any fortune. So he headed for Spain, where he was not as well known. He tried his usual approach, leaning on well-placed contacts (often Freemasons), wining and dining with nobles of influence, and finally arranging an audience with the local monarch, in this case
Charles III. When no doors opened for him, however, he could only roam across Spain, with little to show for it. In Barcelona, he escaped assassination and landed in jail for six weeks. His Spanish adventure a failure, he returned to France briefly, then to Italy.
Return to Venice
In Rome, Casanova had to prepare a way for his return to Venice. While waiting for supporters to gain him legal entry into Venice, Casanova began his modern Tuscan-Italian translation of the
Iliad, his History of the Troubles in Poland, and a comic play. To ingratiate himself with the Venetian authorities, Casanova did some commercial spying for them. After months without a recall, however, he wrote a letter of appeal directly to the Inquisitors. At last, he received his long sought permission and burst into tears upon reading "We, Inquisitors of State, for reasons known to us, give Giacomo Casanova a free safe-conduct ... empowering him to come, go, stop, and return, hold communication wheresoever he pleases without let or hindrance. So is our will." Casanova was permitted to return to Venice in September 1774 after eighteen years of exile.
At first, his return to Venice was a cordial one and he was a celebrity. Even the Inquisitors wanted to hear how he had escaped from their prison. Of his three bachelor patrons, however, only Dandolo was still alive and Casanova was invited back to live with him. He received a small stipend from Dandolo and hoped to live from his writings, but that was not enough. He reluctantly became a spy again for Venice, paid by piece work, reporting on religion, morals, and commerce, most of it based on gossip and rumor he picked up from social contacts.
 He was disappointed. No financial opportunities of interest came about and few doors opened for him in society as in the past.
At age 49, the years of reckless living and the thousands of miles of travel had taken their toll. Casanova's smallpox scars, sunken cheeks, and hook nose became all the more noticeable. His easygoing manner was now more guarded.
Prince Charles de Ligne, a friend (and uncle of his future employer), described him around 1784:
He would be a good-looking man if he were not ugly; he is tall and built like Hercules, but of an African tint; eyes full of life and fire, but touchy, wary, rancorous—and this gives him a ferocious air. It is easier to put him in a rage than to make him gay. He laughs little, but makes others laugh. ... He has a manner of saying things which reminds me of
Figaro, and which makes them sound witty.
Venice had changed for him. Casanova now had little money for gambling, few willing females worth pursuing, and few acquaintances to enliven his dull days. He heard of the death of his mother and, more paining, visited the deathbed of Bettina Gozzi, who had first introduced him to sex and who died in his arms. His Iliad was published in three volumes, but to limited subscribers and yielding little money. He got into a published dispute with
Voltaire over religion. When he asked, "Suppose that you succeed in destroying superstition. With what will you replace it?" Voltaire shot back, "I like that. When I deliver humanity from a ferocious beast which devours it, can I be asked what I shall put in its place." From Casanova's point of view, if Voltaire had "been a proper philosopher, he would have kept silent on that subject ... the people need to live in ignorance for the general peace of the nation".
In 1779, Casanova found Francesca, an uneducated seamstress, who became his live-in lover and housekeeper, and who loved him devotedly.
 Later that year, the Inquisitors put him on the payroll and sent him to investigate commerce between the Papal states and Venice. Other publishing and theater ventures failed, primarily from lack of capital. In a downward spiral, Casanova was expelled again from Venice in 1783, after writing a vicious satire poking fun at Venetian nobility. In it he made his only public statement that Grimani was his true father.
Forced to resume his travels again, Casanova arrived in Paris, and in November 1783 met
Benjamin Franklin while attending a presentation on aeronautics and the future of balloon transport.
 For a while, Casanova served as secretary and pamphleteer to Sebastian Foscarini, Venetian ambassador in Vienna. He also became acquainted with
Lorenzo Da Ponte,
Mozart's librettist, who noted about Casanova, "This singular man never liked to be in the wrong."
 Notes by Casanova indicate that he may have made suggestions to
Da Ponte concerning the libretto for Mozart's
Final years in Bohemia
In 1785, after Foscarini died, Casanova began searching for another position. A few months later, he became the librarian to Count Joseph Karl
von Waldstein, a
chamberlain of the emperor, in the
Castle of Dux,
Bohemia (now in the
Czech Republic). The Count—himself a Freemason, cabalist, and frequent traveler—had taken to Casanova when they had met a year earlier at Foscarini's residence. Although the job offered security and good pay, Casanova describes his last years as boring and frustrating, even though it was the most productive time for writing.
 His health had deteriorated dramatically, and he found life among peasants to be less than stimulating. He was only able to make occasional visits to
Dresden for relief. Although Casanova got on well with the Count, his employer was a much younger man with his own eccentricities. The Count often ignored him at meals and failed to introduce him to important visiting guests. Moreover, Casanova, the testy outsider, was thoroughly disliked by most of the other inhabitants of the Castle of Dux. Casanova's only friends seemed to be his fox terriers. In despair, Casanova considered suicide, but instead decided that he must live on to record his memoirs, which he did until his death.
Prague, the capital city and principal cultural center of Bohemia, on many occasions. In October 1787, he met
Lorenzo da Ponte, the librettist of
Wolfgang Amadeus Mozart's opera
Don Giovanni, in Prague at the time of the opera's first production and likely met the composer as well at the same time. There is reason to believe that he was also in Prague in 1791 for the coronation of Holy Roman Emperor
Leopold II as king of Bohemia, an event that included the first production of Mozart's opera
La clemenza di Tito. Casanova is known to have drafted dialogue suitable for a Don Juan drama at the time of his visit to Prague in 1787, but none of his verses were ever incorporated into Mozart's opera. His reaction to seeing licentious behavior similar to his own held up to moral scrutiny as it is in Mozart's opera is not recorded.
In 1797, word arrived that the
Republic of Venice had ceased to exist and that
Napoleon Bonaparte had seized Casanova's home city. It was too late to return home. Casanova died on June 4, 1798, at age 73. His last words are said to have been "I have lived as a philosopher and I die as a Christian".
 Casanova was buried at Dux (nowadays
Duchcov in the Czech Republic), but the exact place of his grave was forgotten over the years, and remains unknown today.
