The caption for the photo said: "Stone panel from the North-West Palace of Ashurnasirpal II at Nimrud, northern Iraq, neo-Assyrian, 883–859BC." so it's in the neighborhood of 3,000 years.
I find it very interesting to see the level of craftsmanship in ancient art. Even the cave drawings in France, which are far older, show a good hand at draftsmanship IMO.
