If you are wanting to discover more about one of history's greatest and most dramatic female artists, then this is not the book that would be the best starting point. Earlier works by Mary D. Garrard, such as her "Artemisia Gentileschi" (1989), would suit the new reader much better.
Garrard, in the current book, examines just two paintings, a Magdalen and a Susanna & the Elders, in great detail, dissecting their attributions on stylistic, historical, and radiographic grounds. As in her previous work, she takes a strong pro-feminist view and replies to many of her feminist critics.
It is not an easy-reading book, nor was it intended to be. However, it is a must for the hard-core Artemisia fan.
