Book excerpt: "Eminent medievalist Jean Favier introduces and analyzes the political, social, moral, and economic milieux of the late Middle Ages that engendered Europe's transformation from feudalism to capitalism. ... Favier reveals that the ultimate consequence of this risk-taking was not merely the accumulation of wealth by such families as the Medici and the Fuggers, but the transposition of social and aesthetic values upon the populace, leading to the rise of the middle class."--Jacket.
