On the back of the painting it says Souvenir d'Uccello. Paolo Uccello (1397-1475) was an Italian painter and a mathematician who was notable for his pioneering work on visual perspective in art. In his book Lives of the Artists Giorgio Vasari claims that Uccello was obsessed by his interest in perspective and that he would stay up all night in his study trying to grasp the exact vanishing point. In his three piece painting The Battle for San Romano he uses the lances to create perspective, which Constant pays tribute to in this painting.
