Etymology and History

Name Variants

• Revati
• Poushna

Pousna is also the name of the 27th nakshatra and specifically its yogatara (main star) Revati is assigned ζ Psc. This has the presiding deity as Pusan, the Sun. The word Pousna is derived from Pusan.

Identification and Main Star

Revati's shape in temple illustrations shows a group of five stars. It matches a characteristic arch pattern including its determinative star (ζ Psc) in the Pisces/Andromeda area. We arrive at the identification with Z Psc as determined from the coordinates of Suryasiddhanta (Ref).

In the catalogue of stars provided by Nityananda of 15th century the entry correponds to the name Pousna, the ecliptic longitude if 359 degrees and the latitude zero. This position is midway between zeta Psc and Epislon Psc. Hence we propose the name Pousna for epsilon Psc.
