National Gallery Technical Bulletin: Volume 37

This volume continues the National Gallery’s acclaimed series of Technical Bulletins with a selection of studies across the range of the collection, jointly authored by experts in the field of conservation and the scientific examination of paintings. Contributions include an account of the development of the composition of The Virgin Adoring the Child with Saint Joseph by Fra Bartolommeo (1472?-1517), and the painting’s relationship to other works; a study of underdrawing practices in three flower paintings by Paulus Theodorus van Brussel (1754-1795); a critical reassessment of six landscape paintings by Charles-Francois Daubigny (1817-1878); a material comparison of the two most closely linked Sunflower paintings by Vincent van Gogh (1853-1890); and the findings of the latest technical examination, including new X-ray fluorescence mapping results, of two portraits by Francisco de Goya (1746-1828), Don Andres del Peral and The Duke of Wellington.
