This book is a collection of essays written by one of the founders of the Mexican Muralist Movement, between 1928 and 1945. Along with Jean Charlot's compilation of testimonials "The Mexican Mural Renaisance" it constitutes a basic reading "non-official" to understand -outside the quite self-indulgent and inaccurate "historical" research written insofar- one of the most fascinating periods of Modern Art in the Americas and help us to know better one of his main figures, though poorely known. It is a witty and ironical book at the height of the best of Chesterton's.
