The twins begin with an egg. Leda of Sparta bore two sons: Castor, mortal, fathered by her husband; Polydeuces, immortal, fathered by Zeus in the shape of a swan. They were inseparable: horseman and boxer, Argonauts both. When Castor was killed in a cattle feud, Polydeuces refused an immortality his brother could not share.
Zeus offered the compromise the constellation records: the brothers split one immortality between them, alternating days between Olympus and the underworld. Sailors took them as patrons, and named the twin flames that dance on masts after a storm for them. Brotherhood, in this sign, is a schedule: one up, one down, forever taking turns.
Babylon saw twins here too: MASH.TAB.BA.GAL.GAL, the Great Twins, the gate-gods Lugal-irra and Meslamta-ea, who stood guard at doorways to the netherworld. A pair watching a threshold between worlds: the Greek story of alternating days is new, but the idea underneath it is not.
Two bright heads sit side by side, and for once the map is honest: two nearly parallel chains of stars run south from them, stick-figure bodies. Pollux, the immortal twin, outshines his brother, the sky’s quiet comment on the myth. Castor returns the favour by being six stars in one, a sextuple system pretending to be a single point of light.
