The bronze head of an akkadian ruler is a rare example of in ancient art.

I believe the correct answer is: Naturalism.

The bronze head of an Akkadian ruler Sargon, who united Sumer and other Mesopotamian territories, represents a rare example of Naturalism in ancient art as it is life-sized bronze head, which has sharp geometric clarity, locks of hair, curled lips and a wrinkled brow.

they most likely have a instrumental version. just look it up on google.
