Etymology and History

For Bayer (1603), this star is γ Scorpii with no proper name but in the register for the Scorpius-star chart, he lists "Virgilius brachium" among other (Greek and Arabic) designations for this star. Allen (1899, 368/9) that Vergil had not meant it as a star name but only as a marker for the "claws", so it was never meant as a proper name.
