Gemini is a Mutable Air sign. It is ruled by Mercury and associated with the 3rd house. The Sun is in Gemini from late May to late June, which marks the transition from spring to summer in the Northern Hemisphere. Gemini’s symbol is the Twins, representing duality. Gemini is not looking for the meaning of life; it wants to see reality as it is, to take in all of it, including all the contradictions and opposing viewpoints. Gemini wants to see the trees, not the forest. It wants to see every bird, every species of moss, every gnarled branch.
The polarity of Gemini is Sagittarius, which is Mutable Fire. The Gemini-Sagittarius axis is about information vs. knowledge and facts vs. meaning.
Gemini's symbol is from the Greek twins Castor and Pollux. Castor was mortal, while Pollux was immortal, they had different fathers and contrasting personalities, but were inseparable. The association of Gemini with duality highlights the sign's unique ability to navigate multiple perspectives, adapt to changing situations, and absorb the complexities of human nature.
Gemini is ruled by Mercury, or Hermes in Greek. Hermes was a messenger god, a trickster, and in that role was able to move between the world of gods, mortals, and the Underworld. Hermes role as a messenger god reflects Gemini's role of absorbing and transmitting information, but Hermes trickster nature also reveals a deeper aspect of Gemini’s archetype: the ability to manipulate and shape reality through language and perception. This aspect of Gemini can easily enter shadow territory but it is immensely powerful.
Gemini represents a state of innate curiosity that is present in every child. This archetype embodies the fresh, open, and receptive quality of mind that allows us to absorb new experiences and knowledge without filtering them through judgements or preconceived mental frameworks. This is the essence of learning.
But this same unfiltered quality can turn the truth into something that is malleable. The saying that there are "lies, damn lies, and statistics" points to how information is not truth, and more information often does not get us any closer to the truth. The quest for truth is what the polarity of Gemini is about: Sagittarius, ruled by Jupiter. These two archetypes need each other: without Sag, Gemini is lost in a sea of meaningless data; without Gemini, Sag can easily exaggerate in ways that "sound true" but are not grounded in reality, or become dogmatically attached to their point of view & dismiss other perspectives.
