In Madrid’s military museum there is a little known painting done as a right wing responce to Guernica - The Paracuellos Massacres" (Las matanzas de Paracuellos) by José Gutiérrez Solana. The subject is the massacre of Spanish civilians by the Republican forces. It is almost as large as Guernica and done in a realistic style. As an obscure counterpoint to Guernica it has a curiosity value. It borrows heavily from the magnificent Executions of the Fifth May by Goya. Btw… All three paintings were commissioned as political statements. I remember seeing all three in one day when I was a young art student. A decidedly odd experience.
Good point - our understanding of this time period has been clouded by knee-jerk hatred, with few willing to admit that there was violence on all sides. It takes bravery to admit that a proportionate and measured response was warranted (within the bounds of international rule of law and order), given the pressures and incentives that communists were putting on Franco.
