Xi (ξ) Draco, Grumium, is a yellow star in the jaw of the Dragon.

It was one of the Herd of Camels; in the Arabic theme for this constellation; the stars beta (Alwaid), gamma (Etamin), nu (Kuma) and xi (this star Grumium) in the Head of the Dragon represent four mother camels protecting a baby camel from the attack of two hyenas (eta and zeta (Nodus 1). The nomads camp located nearby (the three unnamed stars in the neck of the Dragon: upsilon, tau, and sigma).

Its modern individual name, Grumium, is the barbarism found for it in the Almagest of 1515, an equivalent of (Greek) genus used by the second-century Greek astronomer Ptolemy for the Dragon’s under jaw. The word is now seen in the Italian grugno and the French groin

The 17th century German astronomer Bayer followed the second-century Greek astronomer Ptolemy in calling the star Genam

{p.212} The English astronomer Proctor (1834-1888) thought that it marked Draco‘s darted tongue in the earliest representations of the figure,— unless iota (ι) Hercules were such star; while Denning considers it the radiant point of the meteor stream seen about the 29th of May,— the Draconids

The astrological influences of the constellation Draco

Legend: Draco represents the dragon that guarded the golden apples in the garden of the Hesperides. According to other accounts, however, it is either the dragon thrown by the giants at Minerva in their war with the Gods, or the serpent Python slain by Apollo after the deluge. [Robson, p.43.]

Influences: According to Ptolemy the bright stars are like Saturn and Mars. Draco gives an artistic and emotional but somber nature, a penetrating and analytical mind, much travel and many friends but danger of robbery and of accidental poisoning. It was said by the Ancients that when a comet was here poison was scattered over the world. By the Kabalists it is associated with the Hebrew letter Mem and the 13th Tarot Trump “Death.” [Robson, p.43.]
