Michelangelo's David (1501-1504): This Italian Renaissance masterpiece, The David, has a remarkable history. At the start of the 15th century, the governors of the Cathedral of Florence decided to commission twelve large Old Testament figures installed along the edge of the Santa Maria del Fiore's roof. When, decades later, it was the figure of the David's turn, a huge, expensive block of Carrara marble was purchased. After various artists had failed to complete the enormous job, the still rough block lay untouched for 25 years, at the mercy of the elements. Until Michelangelo, then only twenty-six years old, managed to convince the principals that he could turn it into something.
