Rubem Valentim (1922–1991) was a Brazilian painter, sculptor, engraver and teacher whose artistic practice uniquely combined Afro-Brazilian spiritual symbolism with geometric abstraction and modernist ideas. Born in Salvador, Bahia, Valentim began painting in the 1940s as a self-taught artist, initially producing figurative work before developing a distinctive abstract language rooted in ritualistic and cultural references. He graduated in dentistry in 1946 but soon left the profession to focus on art, later earning a degree in journalism from the Federal University of Bahia and publishing essays on artistic theory.
In the late 1940s, Valentim participated in the Movement for the Renewal of Plastic Arts in Bahia, exploring new visual languages alongside contemporaries such as Mário Cravo Júnior and Carlos Bastos. In 1963, he moved to Rome where he further developed his artistic vocabulary and participated in international exhibitions. In 1966, he represented Brazil at the World Festival of Black Arts in Dakar, Senegal, emphasizing his commitment to Afro-Atlantic cultural dialogues.
Upon returning to Brazil, Valentim settled in Brasília, teaching at the University of Brasília and producing major public works, including a marble mural for the NOVACAP headquarters in 1972 and the large concrete sculpture “Syncretic Structure of Afro-Brazilian Culture” at Praça da Sé in São Paulo in 1979. His visual language is defined by geometric forms such as lines, circles, cubes and arrows, derived from the iconography of Afro-Brazilian religions like Candomblé and Umbanda. These abstract signs function as a unique system of symbols that bridges the sacred and the rational, reflecting Brazil’s cultural miscegenation and addressing historical and political themes from colonial legacies to 20th-century authoritarianism.
Valentim exhibited widely in Brazil and internationally, including repeated participation in the São Paulo Biennials. His work is held in major collections such as the Museum of Modern Art in New York, Pinacoteca do Estado de São Paulo, Museu Afro Brasil, Museu de Arte Moderna da Bahia, and the Colección Patricia Phelps de Cisneros. He died in São Paulo in 1991, leaving a body of work that remains foundational to Afro-Brazilian abstraction and its dialogue with global modernism.
