Volume 36 completes the study begun with Volume 34 (in 2013) of the painting materials and technique of the most influential artist of the 16th century, by the National Gallery, a global center for research into Venetian painting. An introduction addresses the consistencies and variations in Titian's practice, including the use of new materials such as the blue pigment smalt. Entries cover eight key works dating from 1540, and a final essay discusses the conservation history of Diana and Actaeon and Diana and Callisto, the two great mythological paintings recently acquired by the National Gallery and the National Galleries of Scotland.
