Constellation Kulou the Armory

28♎02 to 20♏14

Kulou consists of 10 stars: 6 form the walls of the armory, while the 4 stars in the southwest corner act as watchtowers. Around Kulou are 5 “pillars,” each made of 3 stars, that support the armory. Within Kulou are 4 smaller stars forming a square called “Heng,” symbolizing balance, and some historical records suggest it represents soldiers training in the armory. ^[2]

Ma Duanlin (1317)

The Kulou (Storehouse and Tower) asterism consists of ten stars: the six large stars form the Storehouse (Ku), while the four southern stars form the Tower (Lou); they are located south of the Jiao (Horn) mansion. It is also known as the Celestial Storehouse, the repository for military chariots. Flanking it are fifteen stars: those clustered in groups of three form the Pillars (Zhu), while the four small stars in the center form the Crossbar (Heng); together, they govern the deployment of troops. Astrological interpretations state: “If the stars within the Storehouse are invisible, armies will converge from all directions; if no stars appear, a subordinate will plot against the ruler; if the stars shine brightly but waver, troops will be dispatched in all directions; if all stars vanish, the state is left without a ruler.” ^[3]

Song History (1346)

Koulou (Storehouse) consists of ten stars; the six larger ones form a warehouse, and the four to the south form the Lou (Tower). They are located south of Jiao (Horn) Mansion. It is also known as Tianku (Celestial Storehouse), which serves as the repository for military chariots. Fifteen stars surround it, grouped in threes forming the Zhu (Pillars), and the four small stars in the center form the Heng (Crossbeam).
If the stars have sharp points or flare with rays, warfare erupts; if a star disappears, subordinates will rebel. If they move, generals will be on campaign. If bright and stable, it is auspicious; if dim or void, it is ominous.
If Jupiter transgresses Koulou, the ruler presides over war. If Mars transgresses it, it signifies war and drought. When the Moon enters Koulou, it indicates war. If a comet or bōxīng (a hairy, hazy, or rayed star) enters it, war and famine will occur. If an intruding guest star enters, foreign military forces will rise up. If a falling star or meteor enters it, all troops will be deployed. If red cloud formations enter, both the interior and exterior will experience unrest. If Tiaku produces a horn-like formation (flares), war is imminent. ^[4]
