This book, written in 1930, contains careful graphic representations of the 74 pages comprising the Dresden Codex. The hieroglyphs and pictorial illustrations found on the pages of the codex have been meticulously and finely drawn by Carlos A. Villacorta to bring out their smallest details. At the same time, J. Antonio Villacorta C. describes and comments (in Spanish) upon each element of the pages. This is a valuable book for the scholar.
