Mythological Background
In Greek mythology, Scorpius represents the giant scorpion sent by the goddess Artemis to kill the hunter Orion. According to the myth, the scorpion’s sting was fatal, but after the scorpion killed Orion, both were placed in the sky by Zeus—on opposite sides of the celestial sphere, so they would never be seen at the same time. The story symbolizes the eternal struggle between predator and prey, as well as the power of nature.
Scorpius has appeared in various cultures, often associated with danger and protection. In Babylonian astronomy, it was seen as a guardian figure.
Cultural Significance
Scorpius has been a prominent constellation for navigation and timekeeping, particularly in the Southern Hemisphere, where it is visible during the summer months. Its connection to the zodiac sign Scorpio has also made it an important symbol in astrology, representing intensity, transformation, and passion.
