This is Volume I of the three-volume catalogue raisonné of all drawings considered by the authors to be by Rubens. It covers the years 1590–1608, Volumes II and III dealing, respectively, with the periods 1609–20 and 1621–40.

It is the first publication that presents the artist’s entire drawn oeuvre in chronological order, previous such publications containing only selections of drawings. By leafing through the illustrations, this arrangement provides the user with a quick visual impression of the variety of techniques, media, subject and functions of Rubens’s drawings at an one time. 

Volume I consists of the drawings of the artist’s childhood, apprenticeship and first years as a master in Antwerp to his formative years in Italy, spent mostly in Mantua and Rome, with an excursion to Spain.

These are the years primarily devoted to learning and absorbing the art of the past, from sixteenth-century German and Netherlandish prints to the works of the ancient and Italian Renaissance masters. A large number of these drawings consists of copies after the works of other artists, largely executed as part of the artistic training at the time.
