When did Michelangelo sculpt the David?
The Battle of Anghiari (Leonardo da Vinci)
In 1504 Leonardo da Vinci was given the commission by gonfaloniere Piero Soderini, a contract signed by Niccolò Machiavelli, to decorate the Hall of Five Hundred. At the same time his rival Michelangelo, who had just finished his "David", was designated the opposite wall. This was the only time that Leonardo da Vinci and Michelangelo worked together on the same project. The painting of Michelangelo depicted an episode from the Battle of Cascina, when a group of bathing soldiers was surprised by the enemy. However Michelangelo did not stay in Florence long enough to complete the project. He was able to finish his cartoon, but only began the painting. He was invited back to Rome in 1505 by the newly appointed Pope Julius II and was commissioned to build the Pope's tomb.
Manchester Madonna
The Madonna and Child with St John and Angels (c. 1497), also known as The Manchester Madonna, is an unfinished painting attributed to Michelangelo in the National Gallery, London. It is one of three surviving panel paintings attributed to the artist and is dated to his first period in Rome. The painting's attribution to Michelangelo was in doubt for much of the 19th and 20th centuries, but now most scholars are in agreement. The work first came to public attention in the Art Treasures Exhibition in Manchester in 1857, hence the title the “Manchester Madonna”.
