July 26 – José Oiticica Filho dies.

Sculptor Jackson Ribeiro introduces Oiticica to the Escola de Samba Estação Primeira de Mangueira [Mangueira School of Samba], where the artist becomes a fan and enthusiastic passista, or samba solo dancer. He frequents the shantyown community and strikes up friendships with Nildo, Miro, Jerônimo, Mosquito, Rose, Maria Helena, and many others.

After witnessing a remarkable scene in Rio de Janeiro’s North Zone – a precarious, improvised construction made by a beggar from four wooden slats, ropes and other elements, among which he makes out the word “Parangolé” written on a piece of burlap – the experience suggests to him the title for a new series of works he is developing at the time.

Death of Manuel Moreira (1941-1964), also known as Cara de Cavalo [Horse Face]. This famous outlaw had murdered Detective Milton de Oliveira Le Cocq after a four-month manhunt, having been finally shot to death by police in the city of Cabo Frio, State of Rio de Janeiro. A friend of Hélio Oiticica, the artist paid tribute to him in 1966 with B33 Box Bólide 18.

In furious indignation and to the applause of other artists, journalists, critics and the audience, the artist abandons the building and continues the parade throughout the museum’s gardens.

"Bases Fundamentais para Definição do Parangolé" [Cornerstones for a Definition of Parangolé] and "Anotações sobre o Parangolé" [Notes Concerning Parangolé] appear in a mimeographed artist’s edition on the occasion of the “Opinião 65” exhibition.
