Origin of Constellation

Ashadha means The Invincible and refers to two asterisms in Sagittarius. The First (Purva A.) is depicted as a group of two stars marking a horn or stinger. They are identified with δ and ε Sagittarii, the "arrow" of the Greek and Babylonian archer. The identification of δ is certain because of given coordinates in the 2nd millennium but instead of ε Sgr it could also be γ Sgr (at the tip of the arrow): the three stars form a racognizable pattern.
