These monkeys fit the niche in respect of
height, width and depth.
The arm and hand positions of the monkey
seen to the left of the Uffizi drawing matches the arm and hand position of these two
monkeys.
The Uffizi drawing shows that the legs of
the two monkeys are in two positions. These two monkeys do match the leg position of the
right hand monkey in the drawing.
The right arm and finger pointing up
relate closely to Giambolognas famous Mercury.
The monkeys belong to the fountain in as
much as the right arm and finger could be pointing up to the marble Samson and a
Philistine and the left hand could be cupped to catch water falling from the basin above.
These two monkeys are identical in pose
but the Uffizi drawing shows the missing monkeys are in two poses. There is a precedent
for this configuration. The Neptune Fountain by Giambologna has a set of four boys holding
dolphins. These are arranged in two pairs of two poses and alternating at each corner. The
missing monkeys could well be made the same way, namely two pairs, two poses and
alternating in each niche.
The monkeys are in different weathered
states, one matt and one shiny, consistent with being in different positions around the
fountain.
There are traits of Giambologna, manicured
fingernails, hammered finish, impassive expression.
X-radiographs taken at Tower of London
reveal plugs and use of square core pins (chaplets), evidence of lost wax casting.
The metal is a gun metal dated to the 16th/17th
century. Giambologna used gun metal.
The metal is unrefined and has a high lead
content. Many of Giambolognas small bronzes are leaded bronzes.
The monkeys are lifelike. Bronze birds in
the Bargello Museum, Florence, attributed to Giambologna are lifelike.
The monkeys are not fully worked up, there
would be no need if they were designed for a fountain upon which they would be viewed at a
distance.
There would appear to be a similarity in
the features of these monkeys with the head of a carved stone monkey on the impressive
portal of the Casino Medicio at San Marco. The fountain of Samson and a Philistine was in
a courtyard inside.
