The French poet Louis Aragon once said that Ritsos was "the greatest poet of our age." He was unsuccessfully proposed nine times for the Nobel Prize for Literature. When he won the Lenin Peace Prize (also known as the Stalin Peace Prize prior to 1956) he declared "this prize it's more important for me than the Nobel". His poetry was banned at times in Greece for its left wing content. Notable works by Ritsos include Tractor (1934), Pyramids (1935), Epitaph (1936), and Vigil (1941–1953). Ritsos mainly wrote poems with political content, "serving communism with his art" as modern philologists describe.
