Today we explore the work of the Renaissance masters Niccolo dell'Arca, Guido Mazzoni, and Antonio Begarelli. Never heard of them? You're not alone. Although their work deserves to be ranked alongside their contemporaries Donatello and Verrocchio and yes, even Michelangelo, these sculptors had the misfortune of living on the other side of the mountains from Florence, in Bologna and Modena, far from the marble quarries, far from the Medici. But sculpture finds a way: beyond the influence of Florence, a rich tradition of large scale terracotta figure sculpture developed over several generations, culminating in some of the most elaborate and daring sculpture you've never seen.
