Gemini : Origin - Representation

Gemini zodiacal signs explained

Gemini is symbolized by twins. In Greek astrology, those twins were Castor and Pollux, twin stars in the sky and heroic brothers in myth. Castor was a great horseman, and Pollux was a champion boxer (ironic, because Gemini is not normally a violent sign). More commonly, the twins are thought of as bright children, which gives Gemini a sense of mirth, innocence, and great wonder.

Gemini is ruled by the planet Mercury, which symbolizes great intelligence, communication (Mercury was the Messenger of the gods), eloquence, inquisitiveness, diversity, travel, speed, and changeability. If you are a Gemini, Wednesday is your lucky day (mercredi in French), and your best color is likely to be silver or gray.
