In 2017, the sculpture was reexamined using
X-radiography and
endoscopic measures alongside the
bare eye. This analysis revealed that the sculpture was
cast in 9-10 distinct parts: the head, body, arms, legs, the anterior parts of the feet, and two fingers. It is likely that the legs were cast separately from the body, although the join-work rendered this aspect of the production unnoticeable. These components were joined through a flow-fusion
welding process; the arms were joined to the body at their basins, the head and legs to the body through platform welding, and linear joins connected the feet to the legs. The primary castings for the arms, body, legs, fingers, and head were made using a bronze composed of around 6%
tin and 19.5%
lead.
Unalloyed copper with around 2% lead was used to make the lips, eyebrows, and nipples. The lips, eyebrows, nipples have uniquely high levels of
iron compared to the rest of the statue, and the eyebrows specifically lack
arsenic. For the
welding process, a
filler metal almost identical to the metals used for the primary castings; however, it differs at the joining point of the pinkie finger to the right hand and of the right arm to the body, both of which contain slightly more tin and less lead than the primary castings. The inscription on the foot is inlayed with silver that is itself alloyed by copper and
gold, which constitute around 3% and 0.5% of the total substance respectively. At some point in antiquity, the fourth toe on the right was broken and repaired; the statue had a
tenon inserted into the foot and the missing part placed on top of it. On this specific part of the statue, a unique alloy is used with only 12% lead and 4% tin. It is afflicted with high levels of
arsenic,
bismuth,
zinc, and
antimony compared to the rest of the statue, further proving that this section of the material was added-on later as a repair. Another, similar pattern of impurities is found in the weld join of the right arm, suggesting that it may also have been reworked as part of a repair.
Lost-wax casting techniques were also utilized to construct the statue. Wax was used to fill the insides of the finer, more precise details such as the nose, fingers, ears, and toes of the statue. It is likely that liquid wax was poured into the molds, which were then inverted to remove excess wax, providing the metal walls with a consistent width of 3-4
millimeters. In contrast to the rest of the statue, the wax-castings of the hair show more evidence of direct intervention; each strand of hair was engraved into the wax and
corkscrew curls were carved into the ends of the hair on each side of the forehead. The neck contains a small bib-like shape that represents the only identified wax-to-wax join in the statue, suggesting that the body and head were once divided and then manually connected to each other during the production process at this point. ==References and Corresponding Notes==
