 Based on Dalí’s autobiography, where he narrates his escape from the revolution in Barcelona in 1935, there was a moment when he was about to be killed and in the background he could hear the sound of a phonograph playing "El Bello danubio azul" ("The Blue Danube"); critics believe that this moment inspired "Rompecabezas de otoño".The person posing in "El escritorio antropomorfo" (1936) models a typical dance pose that was popularly practiced in the Limón technique (“José Limón's approach to dance is based on the technique and movement philosophy of Doris Humphrey, who was his mentor and his artistic adviser.The movements of Doris Humphrey take their forms from the natural movements of the human body and they take their rhythms from breathing”).
