Art Brut, also called art of the imaginary, fantastic or uncommon art, are concepts used to classify the works that seem to have originated from the mysteries and truths deep in the human psyche and on the edge of artistic canons. They were first identified with Jean Dubuffet in late 1940, in a context of rejecting the suffocating culture of the official arts system. In Brazilian folk art, there are many surprising creations that are included in this genre where realism and fantasy blend in large doses. Some authors who invent unprecedented themes are ceramist Manoel Galdino (Pernambuco) and his “Lampião-sereia”, and others who address the universal themes in an absolutely original way include Antonio Poteiro (Goiás) and his work “Tower of Babel”.
