In 1895 Claude Monet exhibited a group of paintings showing the facade of Rouen Cathedral under the changing lights from dawn to dusk and in a variety of weathers. The paintings were sold and dispersed, and this book assembles the 30 paintings in sequence. The text discusses their origin. The pictures are reproduced as individual colour spreads as well as appearing as a sequence in miniature. The author is the great-grandson of Camille Pissarro.
