CHAPTER XVI
LOST AND ATTRIBUTED WORKS
In the course of this study mention has been made
incidentally of several works—no longer in existence, or,
at least, hitherto undiscovered—executed by Verrocchio
for the Medici, the authenticity of which is supported by
the reliable evidence of Tommaso’s Inventory. These
missing works may be briefly recapitulated.
1. The restored antique statue of Marsyas, in purple
marble, “ lo gnudo rosso ” (see p. 94).
2. Three bronze heads which formed part of the fountain
of Careggi, of which the Putto with the Dolphin was the
centre (p. 69).
3. A relief carved with several figures, material and
subject not specified.
4. A panel picture representing the head of Lucrezia
dei Donati.
5 and 6. Standards painted for the Jousts of Lorenzo
and Giuliano dei Medici (p. 82).
7. A metal figure of a lady for the crest of a helmet.
8. Twenty masks, probably portraits executed from
death-masks.
9. Decorative work, presumably armour, for the Duke
Galeazzo Sforza.
