The origin of its name is uncertain, but all of the main theories make it an anatomical reference. The most credible is one that ultimately traces back to "Orion's hand." (The Arabic name for Orion, al-Jauza, means "the Central One.") The giant figure is a warrior archetype, with its setting just after Scorpio rises often depicted as a battle between the two resulting in Orion's death.
Ptolemy characterized the stars in Orion's upper extremities as resembling Mars and Mercury. Ebertin agrees that the star is like "Mars with a touch of Mercury." He wrote:
Elsbeth Ebertin found a period of Node conjunct Betelgeuse when "groups of people died by lightning or were victims of explosions or assassinations."Ebertin wrote:Placed in the angles, preferment, luck, success, and even ever-lasting fame are promised. On the Ascendant and in conjunction with Mars there will be danger of death by lightning, fire explosion, fire arms or similar things.
Robson says, "It gives martial honour, preferment, and wealth." Then (it looks to me like switching gears) he says that with the Sun it shows, "Interest in and ability for occult and mystical subjects; acute diseases, fevers, hour and preferment ending in final ruin." With Moon it gives, "active mind, strong will, turbulent, rebellious under restraint," and various military and quarrelsome notes which sound to me like a Mars version of Moon in Gemini.
