Faience baboon, 7th - 6th C BCE, about 16cm / 6 inches tall.
From the sculpture's gallery description:
"The baboon was usually associated with Thoth, one of the moon gods. This animal has a hole in the crown that once held a lunar disk sitting on top of a crescent moon, an attribute of Thoth. For a 2600-year-old artwork it is in remarkable condition, and though the animal is small in size, its posture and expression command authority."
