Legends of Catherine the Great

During and after the reign of the Empress Catherine II of Russia, whose long rule led to the modernisation of the Russian Empire, many urban legends arose, some based on true events, concerning her sexual behaviour.
Catherine had about 22 male lovers throughout her life, some of whom would reap political benefits from their relationship with her, and many of whom were relatively younger. In addition to her sexual relationships, her multiple relationships with Russian nobles, allegations of her being a nymphomaniac or a libertine, rumours that she liked to collect erotic furniture, and an atmosphere of palace intrigue cultivated by her son Paul I of Russia, led to unflattering portrayals of Catherine.
Some called her the "Messalina of the Neva", while others termed her a nymphomaniac. There is also a legend that she died while having sex with a horse.
Rumours of Catherine's private life had a small basis in the fact that she took many young lovers, even in old age. (Lord Byron's Don Juan, around the age of 22, becomes her lover after the siege of Ismail (1790), in a fiction written only about 25 years after Catherine's death in 1796.) This practice was not unusual by the court standards of the day, nor was it unusual to use rumour and innuendo of sexual excess politically. One of her early lovers, Stanisław August Poniatowski, was later supported by her to become a king of Poland. This would not be the first nor last instance where the Queen would promote one of her lovers to political positions in order to solidify her own position and strengthen her support. For example, Grigory Orlov, an artillery officer from St. Petersburg; helped the queen in the coup against Peter III, and when the Queen took power, she rewarded him by making him a count, as well as naming him General-In-Chief.
One unfavourable rumour was that Alexander Dmitriev-Mamonov and her later lovers were chosen by Prince Potemkin himself, after the end of the long relationship Catherine had with Potemkin, where he, perhaps, was her morganatic husband. After Mamonov eloped from the 60-year-old Empress with a 16-year-old maid of honour and married her, the embittered Catherine reputedly revenged herself of her rival "by secretly sending policemen disguised as women to whip her in her husband's presence", though another account claims that there is no truth in this story. Another unfavorable rumor concerned the legitimacy of her children. Many suspected that the queen's children were not in fact fathered by Emperor Peter III, but by some of the lovers she had taken. Her children Ana and Alexei were also rumored to be illegitimate, and some historians even question the legitimacy of Paul I, due to the fact he was conceived so late into their marriage.
According to some contemporaries close to Catherine, Countess Praskovya Bruce was prized by her as "L'éprouveuse", or "tester of male capacity." Every potential lover was to spend a night with Bruce before he was admitted into Catherine's personal apartments. Their friendship was cut short when Bruce was found "in an assignment" with Catherine's youthful lover, Rimsky-Korsakov, ancestor of the composer; they both later withdrew from the imperial court to Moscow.
In his memoirs Charles François Philibert Masson (1762–1807) wrote that Catherine had "two passions, which never left her but with her last breath: the love of man, which degenerated into licentiousness, and the love of glory, which sank into vanity. By the first of these passions, she was never so far governed as to become a Messalina, but she often disgraced both her rank and sex: by the second, she was led to undertake many laudable projects, which were seldom completed, and to engage in unjust wars, from which she derived at least that kind of fame which never fails to accompany success".
Several stories about the circumstances of her death at age 67 in 1796 originated in the years following her death. An urban legend claims that she died as a result of her attempting sexual intercourse with a stallion—the story holds that the harness holding the horse above her broke, and she was crushed.
Another story claiming that she died on the toilet when her seat broke under her is partly true, in that she did collapse in a bathroom from a stroke, and died in her bed a day later.
This tale was widely circulated and even jokingly referred to by Aleksander Pushkin in one of his untitled poems. ("Наказ писала, флоты жгла, / И умерла, садясь на судно."—literal translation: "Decreed the orders, burned the fleets / And died boarding a vessel," the last line can also be translated as "And died sitting down on the toilet.") There existed also a version on alleged assassination, by spring blades hidden in a toilet seat.
An urban legend states that an erotic cabinet was ordered by Catherine the Great, and was adjacent to her suite of rooms in Gatchina. According to said urban legend, the furniture was highly eccentric with tables that had large penises for legs. Penises and vulvae were carved out on the furniture, the walls were covered in erotic art, statues of a naked man and woman inside, and some versions of the legend state that some erotic artifacts from Pompeii were even brought into Russia to augment this collection.
There are unconfirmed reports of photographs of this cabinet. The rooms and the furniture were allegedly seen in 1940 by two Wehrmacht officers during the Nazi invasion of the Soviet Union, but even if that were true, the rooms and furniture seem to have vanished since then. The account says the Wehrmacht officers filed a report, but no report has ever been found, nor any other records from anyone from before, during, or after World War II, other than the aforementioned legend. Also, the account says the rooms and furniture were seen in 1940, during the invasion of the Soviet Union by Nazi Germany, but the invasion did not start until 22 June 1941. For this reason, historical experts challenge the veracity of such claims. But as all of these stories did not even originate until some years after Catherine the Great's death, it is most likely the cabinet never existed, and the whole story was fabricated as another bawdy tale.
