Mr. Sheppard has turned his considerable talent and experience to recreating the materials and techniques that may have been used by the Old Masters of oil painting--Rubens, Rembrandt, Caravaggio, and Titian , to name a few. Rather than apply thick paint on the canvas, the Masters developed their works slowly, over a period of weeks or months, applying layer upon layer of translucent glazes to a gray or brown underpaining. The result is color that is more luminous and vibrant than paint straight from the tube. Mr. Sheppard also provides directions for recreating the Masters' painting medium, a mixture of oil and varnish with the consistency of jelly. I myself did not have the patience (nor, given the obvious health risks in using the powdered lead and high temperatures the recipe requires, the inclination) to create this medium at home, but I am told it is available commercially. Mr. Sheppard is also thoughtful enough to provide recipes for substitute mediums, for those of us of a less adventurous spirit. As for the techniques themselves, there is no denying the author's pure talent, and his prose is bot engaging and informative, but make no mistake: this is not a book intended for the beginner. The reader can see the progression of each painting in a series of illustrations, but several crucial steps are completed in the space of a paragraph, and only a practiced eye can see precisely how the author has completed each step. I was also disappointed that Sheppard has chosen to create one or, at most, two paintings in the style of each Master. His Titian nude, for example, fairly glows on the page, and his sole Rembrandt recreation, that of an old man, rivals and perhaps exceeds many of Rembrandt's own paintings. I would relish the opportunity to see him create more. Still, in exploring the possibilities of the Old Masters (no records of their actual materials or techniques truly exist, so Sheppard has made at best an exceptionally educated guess), I realized the possibilities that can be achieved in my own painting, with patience, practice, and diligence. At the very least, check the book out of the library, get a fresh canvas, and explore the possibilities yourself. You will take something with you.
