Origin of Constellation
The term Dhanuśarāgra (धनुशराग्र) literally means tip of the arrow. Dhanu - bow, śara - arrow, agra - tip. 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. [2]The coordinates match with γ Sagittarii. The accuracy of the star dials cannot distiniguish between the two stars γ 1 and γ2.
The two astrolabes which have this name engraved are C 006 (undated) and C(001, dated 1604CE) and identified as μ Sagittarii in the catalogue. In the latter, C001, the position actually corresponds to the supernova of 1604 CE. [3] [4]
This star name thus can be for γ1 Sagittarii.
