Octávio was born in the state of Minas Gerais. He worked as a metal worker and a plumber. In 1966 he started to attend the painting studio of the Museum of Images from the Unconscious as an outpatient. He was a very intelligent person, who developed thoughts and ideas with a great power of synthesis. He carried out his work with intensity, often standing up. He preferred to work with crayon and make drawings about the most diverse themes, ranging from animal symbolism to images of archaic rituals, from images that evoke Dionysus, metamorphoses, fantastical beings, to images that have their parallel in alchemical symbolism. He participated in exhibitions in Brazil and abroad.
