 At some stage a landscape in the background showed a mounted rider.The central figure in white at one point had large horns, or possibly bird wings, seemingly growing out of his head.From studying the x-rays art historian Carmen Garrido discovered that the center of the image contained a large white lead impasto beginning at the head of the man looking upwards, and that "both the part on top of the impasto and that which is level with the rest of the painting are identical, and have neither the texture nor the normal structure of the authentic brushstrokes of the painter."
