Early Netherlandish painting, its origins and character.

"The book had a wide impact on studies of Renaissance art and Early Netherlandish painting in particular, but also studies in iconography, art history, and intellectual history in general. The book is particularly well-known for its iconographic treatment of Van Eyck's Arnolfini Portrait as a kind of marriage contract. The book remains influential despite its reliance on black-and-white reproductions of paintings, which led to some errors of analysis."--The books that shaped art history (p. 95).
