Sagittarius. ♐︎

The archer is a case of mistaken identity that was never corrected. Everyone says centaur; Eratosthenes, the sky’s first great cataloguer, objected that centaurs do not use bows and named Krotos instead: a satyr, son of Pan, inventor of archery, who lived with the Muses and invented applause to thank them. They asked Zeus to hang him in the sky.

The objection lost. Art wanted a centaur drawing a bow, and a centaur it got, two natures at cross purposes: beast from the waist down, marksman above. The quarrel is preserved in the star maps, where the figure is drawn horsed or goat-legged depending on which mythographer the engraver had read.

Babylon’s original is stranger than either option: PA.BIL.SAG, a god of the city of Isin, drawn on boundary stones as a winged archer with a horse’s body, a scorpion’s sting, and sometimes a second head. The Greek argument about what the archer is was already old; Babylon had answered ‘everything at once’.

Modern observers see a teapot, spout, lid and handle complete, and the name has stuck for good. The bow’s stars still aim the arrow at Antares, the scorpion’s heart: one constellation holding another at gunpoint. And behind the spout, invisible to the eye, sits the centre of the Milky Way itself. The archer stands guard over the galaxy’s own heart.
