Melusine – the Alchemical Siren or a typical illustration of atwin-tailed siren or mermaid. This creature is associated with numerous stories and legends, and is imbued with symbolic meaning in alchemy. The most common iteration of the siren is as Melusine, a creature from medieval legend. Melusine (sometimes, Melusina) was, according to legend, beautiful woman with a disturbing tendency to transform into a serpent from the waist down while bathing; it is the discovery of this nature that triggers calamity.
As the story is most often told, the cursed maiden is discovered in the forest by Raymond, the Duke of Aquitaine, who begs her to marry him. She agrees, on condition that he never disturb her on a Saturday, when she bathes. Raymond eventually grows suspicious of his young wife, and spies on her- and his shocked reaction to her true appearance reveals his betrayal to Melusine, who transforms herself into a dragon and departs in a shrieking fury. This story can be viewed as a metaphor for sexuality, and the contradictory duality of the female nature as viewed through medieval eyes.
The same dual-nature symbolism is also at work in alchemy, which employs the siren as a more benevolent emblem of enlightenment- the siren of the philosophers. Alchemically, the siren’s two tails represent unity -of earth and water, body and soul- and the vision of Universal Mercury, the all-pervading anima mundi that calls out and makes the philosopher yearn to her.
The Palais Garnier is a 1,979-seat opera house, which was built from 1861 to 1875 for the Paris Opera. It was originally called the Salle des Capucines because of its location on the Boulevard des Capucines in the 9th arrondissement of Paris, but soon became known as the Palais Garnier in recognition of its opulence and its architect, Charles Garnier. The theatre is also often referred to as the Opéra Garnier, and historically was known as the Opéra de Paris or simply the Opéra, as it was the primary home of the Paris Opera and its associated Paris Opera Ballet until 1989, when the Opéra Bastille opened at the Place de la Bastille. The Paris Opera now mainly uses the Palais Garnier for ballet.
The Palais Garnier is “probably the most famous opera house in the world, a symbol of Paris like Notre Dame Cathedral, the Louvre, or the Sacré Coeur Basilica.” This is at least partly due to its use as the setting for Gaston Leroux's 1910 novel The Phantom of the Opera and, especially, the novel’s subsequent adaptations in films andAndrew Lloyd Webber's popular 1986 musical. Another contributing factor is that among the buildings constructed in Paris during the Second Empire, besides being the most expensive, it has been described as the only one that is “unquestionably a masterpiece of the first rank.” This opinion is far from unanimous however: the 20th-century French architect Le Corbusier once described it as “a lying art” and contended that the “Garnier movement is a décor of the grave”.
