Technical Observations: The patina is a predominantly brownish green surface with patches of green malachite. Losses of the surface expose an eroded black layer underneath. The statuette is missing the weapon he would have held in his right hand, while the peg extensions and the bottoms of the feet were recently filed. Numerous casting flaws, such as large open pits, are present, especially on the proper left arm.
This Herakles is a solid cast made by the lost-wax process, and the designs were done in the wax model prior to casting. Some cold work, such as burnishing, was done after casting.
