Final answer:
The Riace Warriors are bronze sculptures dating back to around 460-450 BC that exhibit advanced Greek sculpting techniques and include additional materials like silver and copper for realism.
Step-by-step explanation:
The Riace Warriors are two prominent examples of Early Classical Greek sculpture, dating back to around 460-450 BC. These life-size statues are crafted from bronze and were adorned with additional materials such as silver for the teeth and inlaid eyes, as well as copper for the lips and nipples to heighten their lifelikeness. Primarily created using bronze, these sculptures display a remarkable degree of realism through the use of contrasting materials and advanced sculpting techniques of the time, signifying the Early Classical or Severe Style which is distinguished by more naturalistic forms and dynamic poses compared to the rigidity of the Archaic style. They were originally discovered off the coast of Riace, Italy, and now reside in the Museo Archaeologico Nazionale Reggio Calabria.
