The Correr Museum announced the attribution Friday in its newsletter, the Italian news agency ANSA reported. The painting, depicting Mary holding the body of her son, Jesus Christ, was in a museum storeroom.
The find is the second at the museum in two years. In 2011, restoration of a Madonna and Child turned up the signature "Vethor Scharpaco" or Carpaccio.
Carpaccio did most of his work from 1490 to 1519. His best-known works are a series of nine wall paintings, "The Legend of Saint Ursula," originally done for a Venetian church dedicated to the saint.
