	~~An ancient Greek name, meaning "The Guard"~~.

	==Etymology and History==		==Etymology and History==
			The ancient Greek name unambiguously means "The Guard". He is depicted in the shepherd of [[Bootes]] whose main star this is, and who was called The Ploughman in ancient Greek. In Roman times, it made sense to connect the guard to the seven oxen seen in the Big Dipper, or - in the Egyptian part of the empire - as the hippo goddess guarding the bull's thigh.
