This is the face of the Assyrian Lamassu at the Oriental Institute Museum at the University of Chicago.

Gypsum (?) Khorsabad, entrance to the throne room Neo-Assyrian Period, ca. 721-705 B.C. OIM A7369

This 40 ton statue was one of a two flanking the entrance to the throne room of King Sargon II. A protective spirit known as a lamassu, it is shown as a composite being with he head of a human, the body and ears of a bull, and the wings of a bird. When viewed from the side, the creature appears to be walking; when viewed from the front, to be standing still. Thus it is actually represented with five, rather than four legs.
