Sleeping Cupid (Michelangelo)
The Sleeping Cupid is a now-lost sculpture created by Renaissance artist Michelangelo, which he artificially aged to make it look like an antique on the advice of Lorenzo di Pierfrancesco in order to sell for a higher price. It was this sculpture which first brought him to the attention of patrons in Rome.
