Gemini's glyph (♊) is a simple double-bar shape for ‘the twins’, but the Castor and Pollux myth behind it is about twins who weren't actually equal: one immortal, one not. Click any symbol to copy it instantly.
The Gemini symbol (♊, U+264A) is two parallel vertical bars joined at the top and bottom, a Roman-numeral-II shape standing in for a pair of twins. The myth behind it is Castor and Pollux, the Dioscuri: twin sons of Leda, but by two different fathers, which made them unequal in a way most retellings gloss over. Pollux, son of Zeus, was immortal; Castor, son of Leda's mortal husband, was not. When Castor died, Zeus let the brothers share his own immortality, splitting their time between Olympus and the underworld so neither had to be apart from the other permanently. Gemini runs May 21–June 20, is ruled by Mercury, and is an Air sign with Mutable modality: the sign associated with adaptability and duality.
