A highly qualified study of art forms during the centuries of the Renaissance examines the techniques of the plastic arts and implements with a scholarly lucidity, the theory of their correspondence in literature. Mr. Sypher's writings have appeared in Partisan Review and the art periodicals. Here he presents the sum of his work in essay form, starting with the hypothesis that there are analogies in art forms, defining his terms and surveying the work of other critics in such a way as to bring his own into focus. The four periods into which he divides his Renaissance are conventional ones:- Renaissance, Mannerism, Baroque and Late Baroque. But the study gains its merit in its approach that allies and unifies the art forms with one another and with the underlying thought patterns and world views that produced them. To cite an example, Mr. Sypher comments on the linear, gothic quality of the Divine Comedy by contrasting it with the greatly sharpened dramatic central focus and the deep perspectives of the quattrocento painting. It is this line of thought that makes fascinating reading, and the extent to which it goes- covering the major works of three centuries as well as the previous commentary on them- makes the volume definitive. As the first original work to be published in Doubleday's increasingly successful Anchor Books project, it is also a hopeful milestone in bringing worthwhile books to a larger reading audience.
