The history of the star: Manubrium
Omicron (ο) Sagittarius, Manubrium, called "the Handle", is one of the cluster of stars in the Archer’s face.
A Manubrium is a handle-shaped anatomical part, for example the upper part of the sternum or part of the inner ear, from Latin manus ‘hand’, the star does appear to mark the Archer’s right ear.
The astrological influences of the constellation Sagittarius
The following are Ptolemy’s remarks: "The stars at the point of the arrow in Sagittarius have influence similar to that of Mars and the Moon: those on the bow, and at the grasp of the hand, act like Jupiter and Mars . . . those in the waist and in the back resemble Jupiter, and also Mercury moderately: those in the feet, Jupiter and Saturn." … By the Kabalists Sagittarius is associated with the Hebrew letter Vau and the 6th Tarot Trump "The Lovers." [Robson, p.60.]
The astrological influences of the constellation Sagittarius given by Manilius:
"As for the Archer, when the foremost portion of his cloak rises, he will give birth to hearts renowned in war and will conduct the conqueror, celebrating great triumphs in the sight of all, to his country’s citadels. Such a one will build high walls (moenia from Latin murus) one moment and pull them down the next. But if Fortune favours them too generously with success, the mark of her envy is to be seen on their faces, for she works cruel havoc upon their features. So was it that a dread warrior paid for his victories at the Trebia, Cannae, and the Lake, even before the hour of his retreat, with such disfigurement." [Translator’s note: *Hanibal who lost an eye (Livy 22.2.11: Sagittarius is one-eyed; see p.103] [Manilius, Astronomica, 1st century AD, book 4, p.267]
"But they whose lot it is to be born under the Centaur of double form delight in yoking a team, in bringing a fiery horse to obey the pliant reins, in following herds which graze all over the grasslands, and in imposing a master on every kind of quadruped and taming them: they soften tigers, rid the lion of his fierceness, speak to the elephant and through speech adapt its huge bulk to human skills in a variety of displays. Indeed, in the stars of this constellation the human form is blended with a beast’s and placed above it; wherefore it has lordship over beasts. And because it carries a shaft poised on drawn bow, it imparts strength to limb and keenness to the intellect, swiftness of movement, and an indefatigable spirit." [Manilius, Astronomica, 1st century AD, book 4, p.241.]
The astrological influences of the star Manubrium
The name Manubrium means a handle. Possibly this comes from some sketches of the Archer in which the hand holding the string of the bow is pulled right back to the position of this star. It is a Sun-Mars type, by Ptolemy and must thus be considered one of the `blind stars’. But the same planetary simile is of course symbolic of the fatal potency in the hand that may at any moment release the arrow into flight. To find a major planet in a chart very precisely on Manubrium rather than its neighbors (which are very close in longitude) is likely to show up the more aggressive connotations of the constellation and sign here, we should often find less of the philosopher than the high-performance athlete or the high court judge. The military strategist is also likely to have this star strong. [The Living Stars, Dr. Eric Morse, p.96-97.]
