One of America’s most distinguished art historians, Irving Lavin wrote extensively on the history of art from late antiquity to modern times. His interests focused primarily on the correlation between form and meaning in the visual arts. His numerous publications on painting, sculpture, and architecture include “The Sources of Donatello's Pulpits in San Lorenzo: Revival and Freedom of Choice in the Early Renaissance” (1959); “The House of the Lord, Aspects of the Role of Palace Triclinia in the Architecture of Late Antiquity and the Early Middle Ages” (1962); “The Hunting Mosaics of Antioch and Their Sources: A Study of Compositional Principles in the Development of Early Mediaeval Style” (1963); Bernini and the Crossing of St. Peter’s (1968); Bernini and the Unity of the Visual Arts (1980); Past–Present: Essays on Historicism in Art from Donatello to Picasso (1993); Santa Maria del Fiore: Il Duomo di Firenze e la Vergine Incinta (1999); and Caravaggio e La Tour: La Luce Occulta di Dio (2000). The first two volumes of a projected six-volume edition of his collected works have been published as Visible Spirit: The Art of Gianlorenzo Bernini (2007–09), while the third volume has appeared as Bernini at St. Peter’s: The Pilgrimage (2012). A gathering of his essays on modern and contemporary art has appeared in Italian as L’Arte della storia dell’arte (2008).
