It’s a cultural movement that started at the end of the XVIII Century in Germany and England, and then spreaded through Europe until the 1850s. It expressed itself in art, literature, music, politics. Its ultimate goal is to investigate the human soul to succeed where Reason, that dominated the 1700s, had failed. It manifests itself in a strong pulsion towards evasion to the supernatural realms (gothic novel, spiritism), or through colours, smells, perfumes of far, exotic lands (Esotism, Orientalism), or to the past (nostalgic revival of the medieval period). Everything is always impregnated with a sort of constant melancholy, of ennui (boredom), a sense of impotence against greatest forces.
