This year the works of important Mexican muralists like Diego Rivera, David Alfaro Sequeiros, José Clemente Orozco and Rufino Tamayo, stored in the Palacio de Bellas Artes in Mexico, will be submitted to a process of restoration as part of the permanent program of maintenance done to mural work in the country. The person in charge of the procedure will be Walter Boelstery. The cleaning will be done on 300 square meters of murals and will include the works of Roberto Montenegro, Manuel Rodríguez Lozano and Jorge González Camarena. The intervention has been programmed to have three levels--superficial, medium and deep--but this process depends on the opinions of the specialists once the murals have been cleaned and the damages caused by time and humidity can be detected. Among the works to be restored, one can find: El hombre Controlador del Universo, Diego Rivera (1934); Khatarsis, José Clemente Orozco (1934-1935), Nueva Democracia, Siqueiros (1944); Víctimas de guerra and Víctimas del fascismo, Siqueiros (1945); and by the same muralist, Tormento de Cuauhtémoc and Apoteosis de Cuauhtémoc (1950-1951). Also to be restored are: Nacimiento de la nación, Rufino Tamayo (1952), México de hoy, Tamayo (1953); Liberación or La humanidad se libera, Jorge González Camarena (1957), and Alegoría del viento, de Roberto Montenegro (1928). La piedad en el desierto, Manuel Rodríguez Lozano (1941); Carnaval de la vida mexicana, Rivera (1938), and La tercera internacional, also by Rivera (1933).
