Cincinho was born Inocêncio Alves dos Santos in 1907. He was raised in Muritiba, a state of Bahia, Brazil. Having a barber as a father and cigar maker as a mother, Cincinho learned craftsmanship through his parents. He worked as a decorative wall painter in Cachoeira for many years throughout his adult life. In 1973 at the age of 66, he began to paint. He primarily used wax crayons on paper, delicately depicting the rural scenes and landscapes he remembered from wandering through the Recôncavo in his youth. His skilled use of gradations of pastel colors adds subtle luminosity and poetic nuances. Cincinho painted in the dining room of his home, where he always warmly welcomed family and friends. Since 1977, his work has been exhibited in many galleries and museums around the globe, including Museum of Fine Arts in Rio de Janeiro, Museum of Primitive Art in Assisi in São Paulo, Musée D’Art Naif de L’lle de France in Paris among others.
