on one side
and standing figures of the saints Cosmo and Damian on the other. Some
connoisseurs attribute to his hand several plaques, "Jupiter crushing
the Giants," "Fight between Perseus and Phinaeus," a Dog, &c.

The important works which have perished include the uncompleted chalice
intended for Clement VII.; a gold cover for a prayer-book as a gift from
Pope Paul III. to Charles V.,--both described at length in his
autobiography; large silver statues of Jupiter, Vulcan and Mars, wrought
for Francis I. during his sojourn in Paris; a bust of Julius Caesar; and
a silver cup for the cardinal of Ferrara. The magnificent gold "button,"
or morse, made by Cellini for the cope of Clement VII., the competition
for which is so graphically described in his autobiography, appears to
have been sacrificed by Pius VI., with many other priceless specimens of
the goldsmith's art, in furnishing the indemnity of 30,000,000 francs
demanded by Napoleon at the conclusion of the campaign against the
States of the Church in 1797. According to the terms of the treaty, the
pope was permitted to pay a third of that sum in plate and jewels.
Fortunately there are in the print room of the British Museum three
water-colour drawings of this splendid morse by F. Bertoli, done at the
instance of an Englishman named Talman in the first half of the 18th
century. The obverse and reverse, as well as the rim, are drawn full
size, and moreover the morse with the precious stones set therein,
including a diamond then considered the second largest in the world, is
fully described.
