The astrological influences of the constellation Ophiuchus

It is said to give a passionate, blindly good-hearted, wasteful and easily seduced nature, unseen dangers, enmity 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 16th Tarot Trump "The Lightning Struck Tower". [Robson, p.54.]

The astrological influences of the constellation Ophiuchus given by Manilius:

"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].
