ented sculptor, possibly one who was active or educated
in the circle of a Florentine master toward the end of the
fifteenth century. Finally, to judge from the colors and
patterns employed, the surface decoration—its glazing,
painting, and firing—was the work of a ceramist who
was working in Tuscany or influenced by Tuscan sculp
ture. The work displays not only a palette of vivid and
saturated yellow, green, and blackish blue but also pat
terns—such as the cube and cloverleaf patterns on
Christ's tunic—typical of this area of production
(figs. 17D, 17F).^6
Given the difficulty in pinning down a specific cen
ter of production, this object underwent neutron activa
tion analysis in spring 2001 under the direction of
scientist Michael Hughes, formerly of the British Mu
seum, London. The analysis was carried out at the Uni
versity of Missouri Research Reactor, and the data was
compared against the British Museum database.^7 The re
sults of the analysis show that the clay of this bust orig
inated in Montelupo.
Indeed, several scholars maintain that the produc
tion of sculptural devotional figures and altarpieces was
a specialty of Montelupine ceramic workshops in the
