Teen Ta Tseang Keun[1] (simplified Chinese: 天大将军; traditional Chinese: 天大將軍; pinyin: Tiān Dà Jiāngjūn) or Tëen ta tsëang keun[2] meaning "Heaven's Great General",[3] was a Chinese constellation (星官) in the region of Lóu (婁宿天區). It contained stars of the western constellations Andromeda and Triangulum. Allen based identification of Chinese star names by the English astronomer John Williams (1797–1874) and the naturalist John Reeves.[4] But Allen lacked last word kuen as Tien Ta Tseang[3] and also transliterated it as Tsien Ta Tseang.[5]
