Origin 500 BCE to 100 BCE
The glyph of Gemini is a pair of uprights closed by a bar above and below, read as the twins standing side by side and often equated with the Roman numeral two. The twins of the constellation are Castor and Pollux, the Dioscuri, one mortal and one immortal, who in the Greek account chose to share their days between Olympus and the underworld rather than be parted; the doubled figure is much older still, appearing in Babylonian lists as the Great Twins. In the Byzantine manuscripts the two strokes are drawn horizontally rather than vertically, so the upright modern form is a later convention. The sign is mutable air, and the glyph stands for duality held in one frame: exchange, speech, curiosity, the linking of one thing to another, and the restless doubling of a mind that argues with itself.

A Sign of the Zodiac
Gemini is the third sign, a mutable air sign ruled by Mercury, emblematised by the Twins, occupying the ecliptic degrees leading up to the northern summer solstice. The doubled figure is ancient, going back to a Babylonian pairing of twin gods, but the written glyph that now stands for it is a much later invention of Greek and Byzantine chart making. It first appears with the other zodiacal notation in the Greek horoscope papyri of Roman Egypt, everyday papyrus and ostraka documents of the early centuries of the common era that are the earliest attested source for this kind of astrological shorthand, and was carried forward through centuries of Byzantine manuscript copying, the corpus catalogued by Otto Neugebauer and Henry Van Hoesen in Greek Horoscopes, before European printers gave it a fixed typeset form during the Renaissance, settling the sign into the shape still used in chart software today. Gemini's Unicode codepoint, U+264A, falls in the middle of the consecutive run of twelve zodiac glyphs that the standard placed in its Miscellaneous Symbols block, alongside chess, weather and other pictorial signs spanning U+2600 to U+26FF, when that block was introduced in version 1.1 in 1993.
