The first thing to know about this life of the Italian baroque painter Caravaggio is that it is not a proper biography but rather an informal appreciation by novelist and occasional art critic Prose (Blue Angel). As with the other volumes in the Eminent Lives series, groundbreaking research is not expected. Fair enough. Yet despite her obvious love for the artist, Prose has little of substance to say about him. Once she dispatches with the basic points of the artist's life—that Caravaggio defied the fashion for mannered, pious painting with a gritty but theatrical realism that mirrored the artist's turbulent life—she resorts to the puffed-up style of a student trying to reach a term paper's required length. She stuffs her pages with redundant adjectives ("wan, exhausted, used up," "constant and unchanged") and finds no point too trite to repeat three times: "You can watch an artist realizing that what he is doing is succeeding, that the paint is doing precisely what he wants it to do, that his intention and purpose are finding their way onto the canvas." Even those with only a casual interest in the artist would be better served by Helen Langdon's 1998 biography Caravaggio: A Life, which is as accessible as it is scholarly and is now out in paperback.
