Paul Delvaux: The Study of Nine Paintings by Non-Invasive Methods

Paul Delvaux (1897–1994) was a Belgian Surrealist painter known for his dreamlike and enigmatic compositions. His works often featured nude or semi-nude women and deserted urban landscapes, evoking a sense of mystery and intrigue. Delvaux’s meticulous attention to detail and masterful use of light and shadow added depth and realism to his surrealistic style, making him one of the leading figures of the Belgian Surrealist movement. Although writings about Paul Delvaux’s work are not lacking, the literature mainly deals with the stylistic and iconographic aspects of his work. Taking an interest in painting materials and the painter’s technique allows us to understand his personality and to apprehend his work in a different way. In order to collect such information, the early painted production of Delvaux was studied in situ with imaging methods (high-resolution photography, infrared reflectography and X-ray radiography) and non-invasive analytical techniques (MA-XRF and Raman spectroscopy). The results obtained for nine oil paintings produced from 1928 to 1958 are discussed in terms of the support, the preparatory layer, the preparatory drawing, the changes in composition and reuse of paintings, the pictorial layer and the dripping phenomenon.
