== Etymology and History source ==
The earliest attestation of this asterism is found in the ''Shishi xingjing'' (Star Canon of Master Shi), compiled in the late 2nd century BCE—though some scholars argue that the canon origins in the 4th century BCE. Prior to the Tang dynasty (618-907), extant star maps and official histories refer to it simply as "Tian Jiangjun" (天将军, "Celestial General"), whereas the ''Shishi xingjing''  employs both "Tian Jiangjun" and "Tian Dajiangjun." From the Song dynasty (960-1279) onward, the longer form “Tian Dajiangjun” became more prevalent.

Despite variations in nomenclature, the ''Shishi xingjing'' clearly identifies this asterism as representing "the Grand General in Heaven" (天之大将军也).<ref>Qutan Xida. Kaiyuanzhanjing 开元占经. Jiuzhou Press, P. 636.</ref> The term ''dajiangjun'' (“Grand General”) emerged in late time of the Warring States (475 -221 BCE) period to distinguish a commander-in-chief from subordinate generals, while ''shangjiangjun'' (上将军, "High General") appears to have been more common at the time. At early time of Emperor Wu of Han (r. 141 –  87 BCE), ''dajiangjun'' was institutionalized as an official title, ranking alongside the Prime Minister but often wielding greater de facto authority, effectively making the Grand General the highest-ranking official beneath the emperor himself.<ref>An Zuozhang, Xiong Tieji. ''Qin Han Guanzhi Shigao'' (Draft History of Qin and Han Dynasty Official Systems). Jinan: Qilu shushe, 2007: 233-251.</ref> Accordingly, the designation of a celestial “Grand General” is more plausibly a development of the post-reform Han imperial system.

The Eastern Han scholar Xi Meng (郗萌) once mentioned a related asterism, ''Tianjiangjun qi'' (天将军旗, “The Banner of the Celestial General”), said to be located beside ''Tian Jiangjun''.<ref>Qutan Xida. Kaiyuanzhanjing 开元占经. Jiuzhou Press, P. 636.</ref> However, further details about this configuration have been lost.
