Gamma Corvi (γ Crv, γ Corvi) is the brightest star in the constellation Corvus. Its traditional name is Gienah, which it shares with Epsilon Cygni. The name "Gienah Corvi" (or "Gienah Ghurab") may be used to distinguish it from this Gienah in Cygnus.
"Gienah" derives from Arabic, from Ulugh Beg's الجناح الغراب اليمن al-janāħ al-ghirāb al-yaman, meaning "the right wing of the crow", although on modern charts it marks the left wing.
Al-janāħ al-ghirāb al-yaman or Djenah al Ghyrab al Eymen was appeared in the catalogue of stars in the Calendarium of Al Achsasi Al Mouakket, which was translated into Latin as Dextra ala Corvi.[6]
In Chinese, 軫宿 (Zhěn Sù), meaning Chariot (asterism), refers to an asterism consisting of γ Corvi, ε Corvi, δ Corvi and β Corvi.[7] Consequently, γ Corvi itself is known as 軫宿一 (Zhěn Sù yī, English: the First Star of Chariot.).[8]
Structure
This star has a stellar classification of B8III, indicating it is a giant star. It is located at a distance of about 165 light years from the Sun. This is a candidate binary star that may have a companion.[9]
Astrology
In astrology, Gienah is supposed to have a similar effect to Mars and Saturn, tending to promote greed and craftiness. It was one of the medieval Behenian stars, associated with onyx, burdock, and a crow-like kabbalistic symbol 
. In this context it is sometimes referred to as Ala Corvi, "the wing of the crow or raven."
Some anstronomer believe that Gamma Corvi was discovered by Ancient Greeks and others believe it was discovered by the Mayans
