Michelangelo responded by completing his most famous work, the statue of David, in 1504. The masterwork definitively established his prominence as a sculptor of extraordinary technical skill and strength of symbolic imagination. A team of consultants, including Botticelli, Leonardo da Vinci, Filippino Lippi, Pietro Perugino, Lorenzo di Credi, Antonio and Giuliano da Sangallo, Andrea della Robbia, Cosimo Rosselli, Davide Ghirlandaio, Piero di Cosimo, Andrea Sansovino and Michelangelo's dear friend Francesco Granacci, was called together to decide upon its placement, ultimately the Piazza della Signoria, in front of the Palazzo Vecchio. It now stands in the Academia while a replica occupies its place in the square.[41] In the same period of placing the David, Michelangelo may have been involved in creating the sculptural profile on Palazzo Vecchio's façade known as the Importuno di Michelangelo. The hypothesis[42] on Michelangelo's possible involvement in the creation of the profile is based on the strong resemblance of the latter to a profile drawn by the artist, datable to the beginning of the 16th century, now preserved in the Louvre.
