Tianfu
Tianfu
Chinese constellation.
Etymology and History
Tianfu contains four stars, and literally translates to "Celestial Drumstick." This asterism belongs to the Wu Xian school and is depicted in yellow on ancient Chinese celestial globes and maps. The origin of this asterism definitely postdates the one referred to as "Hegu (河鼓, Drum at the River）" by the Shi school because, by its literal meaning, Tianfu is used to strike the drum. Since the Hegu was primarily associated with military war drums in astrology, Tianfu is also considered to be related to the military. Additionally, drums were important timekeeping tools in ancient China, so Tianfu is endowed with significant attributes related to timekeeping. According to the anciant Chinese astrologers, if the stars of Tianfu dim, it could lead to inaccuracies in timekeeping.
