In 1922, climbing on scaffolding in the Simón Bolívar amphitheater of the then National Preparatory School -today Antiguo Colegio de San Ildefonso- Diego Rivera was painting his first mural. He was 36 years old and perhaps he never imagined that his work would become a reference of what it means to be Mexican. He told the story of Mexico from his time and beliefs on dozens of walls and staircases with firm strokes and emblematic figures. This powerful Diego is revealed in the murals of the Secretary of Public Education, the Palace of Fine Arts and the National Palace; he also manifests himself in the Dream of a Sunday Afternoon in the Alameda Central, and in the underwater mural of the Cárcamo de Dolores, which was flooded for over 40 years. Diego also decorated theaters and stadiums; he painted wives and lovers, he imagined museums… to follow in his footsteps is to know him as well as the city.
