Origin of Constellation
The term Dhanuśarāgra literally means top of the arrow. Dhanu - bow, śara - arrow, agra - top. This has been found in the catalogue of astrolabes translated from Persian. The names in these star lists of the dials have been coined based on their position. [1]The coordinates match with γ Sagittarii. The accuracy of the star dials cannot distiniguish between the two stars γ 1 and γ2. The image based on the artwork from wikicommons[2] (https://upload.wikimedia.org/wikipedia/commons/7/7e/Sidney_Hall_-_Urania%27s_Mirror_-_Sagittarius_and_Corona_Australis%2C_Microscopium%2C_and_Telescopium.png) represents the position - the red circle envelopes both the stars.
The two astrolabes which have this name engraved are C 006 (undated) and C(001, dated 1604CE) and identified as μMu Sagittarii in the catalogue. In the latter, C001, the position actually corresponds to the supernova of 1604 CE. This star name thus can be for γ1 Sagittarii.
