Chemical Composition: Warrior
XRF data from Artax 2
Alloy: Mixed copper alloy
Alloying Elements: copper, tin, zinc
Other Elements: lead, iron, nickel, silver, antimony, arsenic
Comments: The amount of antimony suggested by the ICP-MS/AAA data is not confirmed by XRF analysis, which detected only a slight trace of antimony.

Technical Observations: The patina is brownish green overall, interspersed with layers of green malachite, red cuprite, and some black; the black is perhaps oxides or sulfides. The warrior is missing his proper left arm and left foot. The break at the left arm reveals bare metal, porosity from casting, overpaint that is removable with solvents, and some corrosion products.
The warrior is a solid cast with details and decorations done in the wax model before casting. The tang projecting from the bottom of the proper right foot is a separate piece of metal that was attached mechanically. The tang has a different surface appearance than the figure, with less corrosion and more tool marks. Surface finishing after casting is evident in some areas where tool marks are visible, such as the top of the helmet.
Although the type and depth of corrosion products present are consistent with long-term burial, comparison with the candelabrum group of a male and female from Marzabotto and other evidence indicate that Harvard’s piece is a copy of a portion of that candelabrum group and therefore not an antiquity. The lack of the left arm on the Harvard warrior could be explained by the fact that, in the original from Marzabotto, the warrior’s left arm embraces the female figure. In the case of the Harvard statuette, there is no clear indication of attachment to another figure. There is also a small flaw on the left thigh of this piece at the location of a point of attachment on the original that does not appear to be the remnant of such an attachment in this version.
