- This is a monumental monography on the early Renaissance sculptor Donatello (c. 1386-1466), a key figure in the revival of classical art forms and the development of Renaissance humanism. The content is organized chronologically, examining Donatello's early works from 1408 to 1415, his significant contributions to Orsanmichele between 1411 and 1425, and his later masterpieces in Florence, Siena, and Padua. Notable sculptures such as the marble "David," "St. Mark," "St. George," and the bronze "Gattamelata" are analyzed in depth. The book also explores Donatello's involvement in architectural projects like the Old Sacristy and his late works, including the twin pulpits created around 1460-1470. Hartt argues that Donatello was not just a master sculptor but a visionary whose work laid the foundation for modern artistic movements. He explores Donatello’s groundbreaking techniques, such as schiacciato (a shallow relief technique creating depth), his use of psychological realism, and his bold departure from traditional medieval styles. The book provides in-depth analyses of Donatello’s major works, including his bronze David, the equestrian statue of Gattamelata, and his expressive relief sculptures. Art historians and critics consider it an essential resource for understanding Donatello’s influence on Western art. Some reviews highlight Hartt’s ability to make complex artistic concepts accessible, while others appreciate his deep contextual analysis of Donatello’s sculptures. On the other hand John Pope-Hennessy, writing for The New York Review of Books, criticized the photographic interpretations by David Finn, suggesting they misrepresented Donatello's sculptures. He also questioned Hartt's analytical approach, stating there was a lack of serious, independent thinking about Donatello.
