In addition to the bronze statue of Perseus and the medallions previously referred to, the works of art in existence today are a medallion of Clement VII commemorating the peace between the Christian princes, 1530, with a bust of the pope on the reverse and a figure of Peace setting fire to a heap of arms in front of the temple of Janus, signed with the artist's name; a signed portrait medal of Francis; a medal of Cardinal Pietro Bembo; and the celebrated gold, enamel and ivory salt cellar (known as "Saliera") made for Francis I of France at Vienna. This intricate 26-cm-high sculpture, of a value conservatively estimated at 58,000,000 schilling, was commissioned by Francis I. Its principal figures are a naked sea god and a woman, sitting opposite each other with legs entwined, symbolically representing the planet Earth. "Saliera" was stolen from the Kunsthistorisches Museum on 11 May 2003 by a thief who climbed scaffolding and smashed windows to enter the museum. The thief set off the alarms, but these were ignored as false, and the theft remained undiscovered until 8:20 am. On 21 January 2006 the "Saliera" was recovered by the Austrian police and later returned to the Kunsthistorisches Museum where it is now back on Kunstkammer display.
