Achilles on an Etruscan Banded Agate Ring Stone, Circa 4th-3rd Century BC

The stone engraved with Achilles mourning the death of Patroclus, with the hero seated on a folding stool, wearing a helmet and a dotted himation around his legs and over his left arm, leaning forward, his right arm bent at the elbow and resting on his thigh, his sheathed sword projecting behind, enclosed within a hatched border.
