Continue eastward along the ecliptic to the next constellation, Sagittarius the Archer.
Scorpius is included in the ancient star catalogs of Eudoxos of Knidos, Aratos of Soli, and Ptolemy.
Gaia sent Scorpius to kill Orion; now they circle on opposite sides of the sky. Reddish heart Antares, can rival Mars. Lost its claws to Libra in Roman times, when the vernal equinox was located in Libra. Fish-hook to Polynesians.
