Since the 1950s, the Colombian art started to have a distinctive point of view, reinventing traditional elements under the concepts of the 20th century. Examples of this are the Greiff portraits by Ignacio Gómez Jaramillo, showing what the Colombian art could do with the new techniques applied to typical Colombian themes. Carlos Correa, with his paradigmatic "Naturaleza muerta en silencio" (silent dead nature), combines geometrical abstraction and cubism. Alejandro Obregón is often considered as the father of modern Colombian painting, and one of the most influential artist in this period, due to his originality, the painting of Colombian landscapes with symbolic and expressionist use of animals, (specially the Andean condor). Fernando Botero, Omar Rayo, Enrique Grau, Édgar Negret, David Manzur, Rodrigo Arenas Betancourt, Oscar Murillo, Doris Salcedo and Oscar Muñoz are some of the Colombian artists featured at the international level.
