Goat attacked by lion

"Seals 842 and 843 clearly show deviation from the Mesopotamian practice that prevailed in the beginning stage of the Achaemenian empire. Though a lion attacking a bull (842) or a goat (843) is one of the stock motifs of Mesopotamian art, the theme became stereotyped after the Middle Assyrian period, and the lifelike representation found in 842 is matched only in Greek gems of the sixth and fifth cneturies. In 843 the subject is renderd with far less expression. The latter seal is notable for two reasons: it is made of dark-green glass, a very unusual material, and the crosshatched section below the animals has parallels only in greco-Phoenician glyptic."--Porada, CANES, p. 105
