Here's what we know:
* Ancient Babylonian Astronomy: Records from 3000 BC mention Scorpius, and it was associated with the god Nergal.
* Ancient Egyptian Astronomy: The Egyptians also recognized Scorpius and associated it with the goddess Serket, a protector against venomous creatures.
* Ancient Greek Mythology: The Greeks saw the constellation as the scorpion that killed Orion, the hunter.
Therefore, the constellation Scorpius has been recognized for at least 5,000 years, if not longer. It's a part of the oldest star patterns known to humans.
