The Conversion of Saint Paul Series at the Courtauld: Rubens's Artistic Process Revealed by New Technical Discoveries

The Courtauld Gallery has three works by Peter Paul Rubens depicting the Conversion of Saint Paul, all dated to ca. 1610–1612: a compositional drawing, an oil sketch, and a finished painting. The serendipitous survival of these works provides insight into Rubens’s creative process and has long been a topic of discussion for art historians. Recent technical study and improved imaging techniques have highlighted Rubens’s extremely fluid approach to the development of the design and revealed complex reworkings of all three compositions. These findings suggest a much longer gestation of these ideas than the 1610–1612 date proposed, and they cast light on Rubens’s broader working practice and his ceaseless striving for aesthetic perfection, combined with a pragmatic approach to the reuse and reworking of his compositions. Building on research done by E. Melanie Gifford, the complex changes revealed by X-ray; by infrared, transmitted, and raking light; and by microscopic examination can be explored using enhanced image tools and navigation. Readers can compare works of art with each other and with their technical images using the “IIIF multi-mode viewer” to better understand Rubens’s artistic exploration of ideas and aid their own research.
