Mythology

According to Greek mythology, it corresponds to the scorpion which was sent by Gaia (or possibly the goddess Hera) to kill the hunter Orion, the scorpion rising out of the ground at the goddess' command to attack. Although the scorpion and Orion appear together in this myth, the constellation of Orion is almost opposite to Scorpius in the night sky. It has been suggested that this was a divine precaution to forestall the heavenly continuation of the feud.

In many versions, however, Apollo sent the scorpion after Orion, having grown jealous of Artemis' attentions to the man. Later, to apologize for killing her friend, Apollo then helped Artemis hang Orion's image in the night sky. However, the scorpion was also placed up there, and every time it appears on the horizon, Orion starts to sink into the other side of the sky, still running from the attacker.

Scorpius also appears in one version of the fable of Phaethon, a foolish mortal who obtained permission to drive the Apollo's sun-chariot for a day. The horses, already out of control in their sky journey became scared when they encountered the great celestial scorpion with its sting raised to strike, and the inexperienced boy lost control of the chariot, as the sun wildly went about the sky. Finally, Jupiter struck him down with a thunderbolt to stop the rampage.

The Chinese included these stars in the Azure Dragon, a powerful but benevolent creature whose rising heralded spring.

Astrology

The astrological sign Scorpio (October 23 - November 21) is associated with the constellation. In some cosmologies, Scorpio is associated with the classical element Water, and thus called a Water Sign (with Cancer and Pisces). Its polar opposite is Taurus.
