The Cleveland Apollo: Apollo Sauroktonos (Lizard-Slayer) or Apollo the Python-Slayer

From the Cleveland Museum of Art record

The Cleveland Apollo was cast in multiple sections using the indirect lost-wax technique. First, molds were taken from a working model (now no longer known or preserved), which was then reproduced in hollow wax sections, each filled with a clay core. After details were added to the wax models, each was encased in clay. Then, the wax was heated, melted out, and replaced by molten bronze. Once cooled, the hollow bronze sections were fused together and finished, patching flaws and adding inlays and other details. Since the initial model was retained, it could be reused, allowing ancient sculptors to create multiples and variations of favorite works. Thus, remarkably, the Cleveland Apollo may once have been one of several such works. The consistently thin walls of the Cleveland Apollo (mostly 5-6 mm thick), together with the nearly invisible joins between most cast sections, show that it was created by highly skilled sculptors and foundry workers. Close looking reveals several noteworthy features. First, ovals atop the right foot mark a fusion weld, where molten bronze pooled to join separately cast sections. Second, small rectangular bronze patches cover parts of the surface (especially the right hip), each carefully cut and then hammered into place over holes or other casting defects. Inlaid lips, nipples, and eyes (the right ancient stone, the left now a modern replacement) added to the lifelike appearance of the sculpture, contrasting with the once bronze-colored skin. Finally, radiography helps to illuminate hidden features, such as the cast edge of the neck of Apollo. Ovals across the top of the right foot show a clear join between separately cast sections.
