History of the star: The Arabic spelling for this quadruple star is Al-Jabhah (1), "The forehead" of the scorpion, Scorpio. This star, Jabbah (nu), along with the other stars on the Head of the Scorpion; Acrab (beta), and Dschubba (delta), were the Euphratean Gis-gan-gu-sur, "the Light of Hero", or "the Tree of the Garden of Light ". In Mesopotamian these were Jia Jan Ju Sur which seems to have meant "the forbidden Tree of Life in Eden". 

It was believed to be included in the Arabic 15th manzil, Iklil al Jabhah, "the Crown of the Forehead". This was one of the fortunate stations, and from this manzil title comes the occasional Iclil.

The Hindus knew the group as their 15th nakshatra, Anuradha, "Propitious" or "Successful", — "Mitra, the Friend", one of the Adityas, being the presiding divinity; and they figured it as a "Row" or "Ridge", which the line of component stars well indicates.

The astrological influences of the constellation given by Manilius:

"The Scorpion presides over arms" [Manilius, Astronomica, 1st century AD, book 4, p.253]

By virtue of his tail armed with its powerful sting, wherewith, when conducting the Sun's chariot through his sign, he cleaves the soil and sows seed in the furrow, the Scorpion creates natures ardent for war and active service, and a spirit which rejoices in plenteous bloodshed and in carnage more than in plunder. Why, these men spend even peace under arms : they fill the glades and scour the woods; they wage fierce warfare now against man, now against beast, and now they sell their persons to provide the spectacle of death and to perish in the arena, when, warfare in abeyance, they each find themselves foes to attack. There are those, too, who enjoy mock-fights and jousts in arms (such is their love of fighting) and devote their leisure to the study of war and every pursuit which arises from the art of war. [Manilius, Astronomica, 1st century AD, p.239-240].
