Trained Baboons
According to this hieroglyphic, the ancient Egyptians once trained their baboons to act as guards and protect their loot from criminals. So, whenever a thief tried to steal anything, these baboons would spot them and attack. The only thing this image doesn’t explain is how the Egyptians taught these baboons how to spot the difference between a regular person and a criminal. But it’s safe to say that the owner used a command like “attack” to get the baboon to go after the criminal.
