Name origin

From its ancient Greek name Ἀρκτοῦρος, "the Guard, or Guardian". Reapplied in Renaissance times. As the Greek word Άρκτος, "bear," also came to mean "north," the meaning can ambiguously be "Guardian of the North" and "Guardian of the Bear", referring to the nearby constellation Ursa Major.
