I took these photos at the Los Angeles County Museum of Art. The reliefs are from interior walls of the palace of Ashurnasirpal II who reigned from 883 to 859 BC. He was the first Assyrian king to use carved reliefs on the interior walls of a palace at the site of Kalhu (now called Nimrud).
Like Greek and Roman statues these reliefs were originally painted. These reliefs had small traces of black, white, red and blue paint when they were first rediscovered in the 1830’s.
