History of the star: A deep yellow star marking the second of the four Knots, or convolutions, in the figure of the Dragon Draco. Nodus secundus or Nodus 11 is the Arabic At-Tinnin, "The great serpent".

It was also called Altaisy, Altais, Al Tais, "the Goat", as the prominent one of the quadrangle, delta, pi, rho, and epsilon, which bore this title at a late period in Arabic indigenous astronomy.

Delta also may have been one of Firuzabadi's two undetermined stars Al Tayyasan, the Two Goatherds.

The astrological influences of the constellation: "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 accidental poisoning. It gives craft, ingenuity, and valor. The Ancients said 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 13^th Tarot Trump, Death". (Robson).
