Fixed Stars in Astrology

13. Constellation – Gemini, the twins



Gemini, the twins, is the constellation which represents in mythology the concept of polarity, light and dark, two faces of the same issue. In the bible this archetype is represented by Cain and Abel, for Egyptians it was Horus, god of the evening, and Set, his evil brother.

In Greek mythology the constellation is associated with the twins Castor and Pollux, children of Leda. In the night when Leda married with Tyndareus, the king of Sparta, she was seduced by Zeus, disguised in a swan. As a result the twins were born, but Castor was the son of the king, while Pollux was the son of Zeus. Castor became a horseman, with skill in art, music, science, while Pollux was famous for his strength and ferocity.


– polarity, duality;

– courage, strength.
