He was a painter, editor, poet, writer, and art critic, best known for his co-founding of Los Diez Pintores Concretos, a group of artists working in geometric abstraction in Cuba from 1958 to 1961.
[2] Oraá and Loló Soldevilla, another abstract artist, his contemporary and wife, opened Galeria Color-Luz in 1957 Havana, which became the rendezvous point for Los Diez as well as, the place where they held a majority of their exhibitions.
Los Diez were the pioneers for the Concrete movement or Concrete Abstraction, a style that defines itself as simply geometrical and without "...representational or drawn-from-life references... a style without narrative or natural connections..."[3] Even after the groups' dissolution in 1961, Oraá represented Cuba in many exhibitions both on the island and abroad and was a significant member in many cultural organizations such as The National Union of Writers and Artists and The National Council of Culture.
Although Los Diez exhibited as a group only three times, they comprised a significant period in Cuban political, social and artistic history in only three years.
"It seems to me that Pedro de Oraá (1931) has always been there, reminding us through his work that a great piece is one that remains firmly on its path, indifferent to the ever-changing winds of fashion that blow.
