Image: "The Death of Zapata" (1937) by Luis Arenal Bastar (1908-1985). Oil on masonite.
Comments: Arenal Bastar was a leftist painter, engraver, muralist, and sculptor, and he was one of the founding members--in addition to other artistic organizations--of the Liga de Escritores y Artistas Revolucionarioes (1933), which organization replaced the Sindicato "Sindicato de Trabajadores Técnicos, Pintores y Escultores, which had been founded by the Soviet Comintern in 1930. In 1940, he was one of Siqueiros' collaborators in the failed assassination attempt on Leon Trotsky's fortress-house in Coyoacán. In the 1930s he worked frequently in places such as New York City and various cities near Los Angeles in the United States. In addition to working with Siqueiros in the failed assassination of Trotsky, he worked closely with him in various art projects to such an extent that in 1977 he was named director of the Siqueiros Workshop in Cuernavaca.
For Siqueiros' portrait of Emiliano Zapata, see: <= Modern Mexican Art #17. For other works by Siqueiros in this series, see: <= #27 and <= #29.
Humanities Question: To answer this question, study Frida Kahlo's self-portrait titled "La columna rota [The Broken Backbone]" (1944) and then compare and contrast that painting with Arenal Bastar's painting above.
