Alabaster bas-relief depicting keepers with dogs. Those keepers were stationed at some points at the edge of the arena, in front of the line of soldiers. The intention is the same; deterring lions from trying to escape. From Room C of the North Palace, Nineveh (modern-day Kouyunjik, Mosul Governorate), Mesopotamia, Iraq. Circa 645-535 BCE.
