The Chimera refers to a dreadful being born of Typhon, a monster of the underwater world, and of Echidna, a serpent woman and sister of the Gorgons, described and depicted as having the head of a lion, the body of a goat, and a tail in the form of a snake, sometimes with a dragon's tail and spewing fire from its mouth. Like other teratogenic beings, it is a symbol of complex perversion. In Greek mythology, the Chimera was killed by the hero Bellerophon, prince of Corinth riding the winged horse Pegasus, provided to him by the muses of Mount Hericon, becoming the prototypical pre-Christian dragon slayer, like St. George and St. Michael. This combat appears in many works of art and on coins from Corinth, where the Chimera was used as a heraldic animal. Analysing the symbol, we can see that its meaning has evolved, in parallel with humanity. Originally it represented the elemental tectonic furies. During the Renaissance it was said of the Chimera that it seduced and led astray the mind of those who abandoned themselves to it, as it represented the imaginative and feverish creations of the subconscious and like no other it described the frustration of unfulfilled desires, which are transformed into exasperation and pain. We see the interpretation given by Paul Diel in his book "Le symbolisme dans la Mithologie grecque", referring to the Chimera: it would be a psychic deformation, characterised by a fertile and uncontrolled imagination, and which could not represent more clearly the psychological reality of the three forms of imaginative perversion, the vanity symbolised by the serpent, the sexual perversion symbolised by the goat, and the social perversion revealing the tendency to dominate represented by the lion. Nowadays the word chimera is used without its symbolic content, referring only to a false idea or illusion of an overflowing imagination. Today's science also calls transgenic animals, obtained by combining traits of different species, chimeras.
