A Chinese constellation within the super-constellation of Kulou (库楼), the Arsenal.
Etymology and History
Heng is a general term for measuring instruments that weigh objects, and it also refers to the graduated arm of a steelyard weighing apparatus. As a verb, it means to weigh, and it is further extended to evaluate certain things or people. As a constellation , 'Heng' is a small one consisting of four stars located within Kulou (库楼). The astrological text Jin Shu - Astronomical Treatise mentions: "The four small stars in the center (of Kulou) are Heng, which is mainly for deploying troops."[1] Perhaps for this reason, Sun & Kistemaker interprets it as 'a place for drilling and examining soldiers'.[2] However, Kulou and Zhu are both nouns. From this perspective, Heng may also be a noun, and it may originally represent a tool for measuring the weight or quality of weapons.
Identification of stars
Due to the relatively obvious position, sufficient brightness, and relatively regular shape of Heng, it has remained unchanged for two thousand years.
