Michelangelo's Pietà depicts the body of Jesus on the lap of his mother Mary after the Crucifixion. If you look closely, the sculptor's signature can be found across Mary's chest. Michelangelo later regretted the vanity of this act, and resolved never to sign another piece of his work.
The Biblioteca Medicea Laurenziana is a historical library in Florence, Italy, containing a repository of more than 11,000 manuscripts. The library is renowned for the architecture planned and built by Michelangelo.
Not long after Michelangelo completed The Last Judgment, the Council of Trent condemned nudity in religious art, decreeing that "all lasciviousness be avoided". Clement's successor, Pope Pius IV, complied with the tenet, and in 1565, the year after Michelangelo's death, had the more controversial nudity painted over by Daniele da Volterra, earning the artist the nickname Il Braghetonne, or "the breeches-maker."
