Influence 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 13th Tarot Trump, Death". (Robson).
