Engagingly written and profusely illustrated, this book offers readers a close-up "view from the scaffolding" of some of the greatest Renaissance wall paintings at the Vatican.   Beginning in the late 1400s, the greatest artists of Renaissance Italy were summoned to Rome, where they decorated the walls and ceilings of the Vatican. Expert restorer Maurizio De Luca spent his forty-year career in the Vatican Museums, including fifteen years as head restorer of the Painting Restoration Laboratory. He personally oversaw some of the most important restorations of the last half century, including wall paintings by Perugino, Botticelli, and others on the walls of the Sistine Chapel; the Pintoricchio wall paintings in the Borgia Apartments; the Raphael Rooms; and the last two frescoes by Michelangelo, in the Pauline Chapel at the Apostolic Palace.   In this accessible and copiously illustrated book, De Luca conveys the kind of knowledge that can only be derived from close personal observation. The reader is offered a stunningly intimate perspective that illuminates the distinctive expressive challenges, choices, and techniques of each artist and demonstrates how the conservation process enriches the understanding and interpretation of these iconic works.
