Juan de Mesa_Master of Passion - Page 114



The colour of the loincloth was made with lead white, plus some
grains of quartz and red earths. The pigments identified in the
hair are red earths, umbers and calcite. Those in the cross, red
earths and calcite.
State of Conservation and Diagnosis9
In general, we can say the support of the sculpture does not
present major problems. Nevertheless, there are some points to
note which include:
· Losses to the support. These were probably caused
accidentally by knocks to the loincloth and crown and, on
the left-hand side between the ear and the beard, there is a
small piece missing from a lock of hair.
· Losses of shape. On the right arm and tips of the toes
small losses are visible, also caused by knocks.
· Alterations and deterioration in the polychromy:
· Burn damage to the polychromy (fig. 83). The left-hand
side of the face is the area most affected. Heat has caused
the loss of the whole surface layer and the remaining
polychromy is very porous and lacks cohesiveness, so that
all the subtle details in this area are quite lost. Heat has

fragile. The areas which have not been damaged by heat,
fortunately most of the work, adhere well to the support.
A peculiar type of cracking has been generated in the flesh areas,
since the general direction of the breaks in the layers is distinctively
horizontal, the opposite direction to the grain of the wood. This
does not occur in the polychromed surface of the loincloth where
there is hardly any cracking. The cross is polychromed in the same
sequence as the figure: a coat of glue, ground layer and colour.
The pigments used in the flesh tones as identified in the laboratory
analyses are:
· Lead white and red earth grains in the first layer for rough
outlining
· Finishing layer, lead white with grains of quartz, calcite
and red earths. In smaller amounts, carmine and vermilion
are also present
· Blood, red lake and lead white
· Binding agent with an oil and protein base.
