Klimt abandons the attempt of painters from the early Renaissance onward to re-create with ever-increasing realism the three-dimensional world on a two-dimensional canvas. Like other modern artists faced with the advent of photography, Klimt sought newer truths that could not be captured by the camera. He (…) turned away from the three-dimensional outside world and toward the multidimensional inner self and the unconscious mind.
