About this star:

Kajam is Cujam, from Caiam, the accusative of Caia, the word used by Horace 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. (Allen).

Influence of the constellation:

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).



Rising:

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 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. (Manilus, book 5 of Astronomica, 1st century AD).
