In Power and Imagination , a noted historian rethinks the evolution of the city-state in Renaissance Italy and recasts the conventional distinction between "society" and "culture." Martines traces the growth of commerce and the evolution of governments; he describes the attitudes, pleasures, and rituals of the ruling elite; and he seeks to understand the period's towering works of the imagination in literature, painting, city planning, and philosophy-not simply as the creations of individual artists, but as the forman expression of the ambitions and egos of those in power.
