This is a great book on Cranach. As others reviewed, the painting reproductions are fabulous. But, the essays are also good. Bodo Brinkman writes a concise essay that gives biographical information on Cranch the Elder. Gunnar Heydenreich contributes a short essay on the physical qualities of Cranach's paintings, from the types of wood panels he painted on to the grounds and pigments, as well as composition and underdrawing. (It's like a snapshot of Heydenreich's book Lucas Cranach the Elder: Painting Materials, Techniques and Workshop Practices. Good, but dense with conservation type information that only specialists will probably be interested in.) The Evans essay goes over possible Italian influences in the work of Cranach. There are 4 other essays by Cranach scholars that are equally interesting and worth reading (I just ran out of time for the review).
Overall: great book!
