History of the star: A sapphire star on the head of the Snake Charmer Ophiuchus. Ras alhague, or Rasalague, is from Ra's al Hawwa' (1), "the Head of the Serpent-charmer", the Moorish El Hauwe. Variations: Rasalauge, Ras Alhagas, Ras Alhagus, Rasalange, Ras al Hangue, Rasalangue, Ras Alaghue, Rasalhagh, Alhague, and Alangue. Al Ra'i, "the Shepherd", was a title from the early Arabic astronomy, the near-by alpha Herculis (Rasalgethi), 6° to the west, being Kalb al Ra'i, the Shepherd's Dog. 

[Star Names, Their Lore and Meaning, Richard Hinchley Allen, 1889]. 

The astrological influences of the constellation: It is said to give a passionate, blindly good-hearted, wasteful and easily seduced nature, together with little happiness, unseen dangers, enmity, strife and slander. Pliny said that it occasioned much mortality by poisoning. This constellation has also been called Aesculapius and held to rule medicines. By the Kabalists it is associated with the Hebrew letter Oin and the 16^th Tarot Trump "The Lightning Struck Tower". (Robson*).

The astrological influences given by Manilius for the constellation Ophiuchus:

When Ophiuchus, encircled by the serpent's great coils, rises he renders the forms of snakes innocuous to those born under him. They will receive snakes into the folds of their flowing robes, and will exchange kisses with these poisonous monsters and suffer no harm. [Manilius, Astronomica, 1st century AD, book 5,  p.333].

One called Ophiuchus holds apart the serpent which with its mighty spirals [gyris] and twisted body encircles his own, that so he may untie its knots and back that winds in loops. But, bending its supple neck, the serpent looks back and returns; and the other's hands slide over the loosened coils. The struggle will last for ever, since they wage it on level terms with equal powers. [Manilius, Astronomica, 1st century AD,  book 1, p.31].

It has a Saturn like character, and some of the undesirable Venus qualities are also present. Connected with these are Neptunian tendencies, making the native especially prone to infectious contamination caused by toxins. People thus influenced are easy going in the use of medical drugs, hallucinatory drugs stimulating foodstuffs, too much good living and overindulgence in tobacco and alcohol. There is danger of insect bites, snakebites or assault from infuriated animals or rabies smitten dogs. If conjunct the Moon, Mars, or Neptune, the native is very prone to infections in general and to epidemic infections. Besides the lower emanations, there are supposedly higher influences attributed to this star, 'though only very few people are able to attune themselves to these influences'. (Fixed Stars and Their Interpretation, Elsbeth Ebertin, 1923)

(Robson*).
