The history of the star: Kajam

from p.245 of Star Names, Richard Hinckley Allen, 1889.

Omega (ω) Hercules, Kajam, is a 4th-magnitude double star in the Club of Hercules.

By some early transcriber’s error, the name is now given as Cujam, from Caiam, the accusative of Caia, the word used by Horace (65-8 B.C.) for the Club of Hercules, which is marked by this star. Gaiam, Guiam, and Guyam, frequently seen, are erroneous.

The Club of Hercules is supposed to have been a separate constellation with Pliny (23-79 A.D.).

The astrological influences of the constellation Hercules

Legend: This constellation was put in heaven as a reminder of the labors of Hercules. According to another account, however, during the war between the Gods and Titans the former all ran to one side of the heavens, which would have fallen had not Atlas and Hercules supported it, and the latter was placed in the sky in commemoration of this service. [Robson, p.46-47.]

Influences: According to Ptolemy it is like Mercury. It is said to give strength of character, tenacity and fixity of purpose, an ardent nature and dangerous passions. By the Kabalists it is associated with the Hebrew letter Daleth and the fourth Tarot Trump "The Emperor". [Robson, p.47.]

The astrological influences of the constellation Hercules given by Manilius:

Manilius associates Hercules with tightrope walking (funambulism):

Hercules, the figure on bended knee and called by the Greek name of Engonasin, about whose origin no certainty prevails. Of this constellation is begotten the desertion, craftiness, and deceit characteristic of its children, and from it comes the thug who terrorizes the heart of the city. If perchance his mind is moved to consider a profession, Engonasin [a Greek title for constellation Hercules meaning Kneeler] will inspire him with enthusiasm for risky callings, with danger the price, for which he will sell his talents: daring narrow steps on a path without thickness, he will plant firm feet on a horizontal tightrope; then, as he attempts an upward route to heaven, (on a sloping tightrope) he will all but lose his footing and, suspended in mid-air, he will keep a multitude in suspense upon himself" [Manilius, Astronomica, 1st century, AD, p.353.]
