Etymology and History

Ashadha means The Invincible and refers to two asterisms in Sagittarius. The Latter (Uttara A.) is depcted as a group of two stars that are typically taken for ζ and σ Sagittarii but they actually form part of a recognizable quadrilateral which is not really logical. Yet, the identification is certain because of given coordinates for σ Sagittarii in the 2nd millennium; whether it was a different asterism BCE, is, of course, not certain.
