Shen, the Three Stars of the White Tiger

Shen, the Three Stars, is the twenty-first of the twenty-eight xiu and the last mansion of the western palace, the White Tiger. It is identified with the constellation Orion, its name recalling the three bright stars of Orion's belt at its heart. In Chinese lore Shen and the mansion Xin, the Heart, stand at opposite ends of the sky and never appear together, an image of separated brothers or estranged friends. In the later astrological tradition its animal totem is the Ape. As one of the twenty-eight lunar mansions Shen closes the seven of the White Tiger. These are the conventions of the Chinese astronomical and calendrical tradition, in which the twenty-eight xiu order the heavens; with the Three Stars the White Tiger of autumn gives way to the Vermilion Bird of the south and summer.

Orion's belt anchoring Shen gives this mansion one of the most visually striking and universally recognised asterisms of any of the twenty-eight, and the same three stars anchor readings in the Vedic scheme, via the neighbouring nakshatra Mrigashira just across the boundary from Ardra, and in the Western fixed-star tradition as Orion's belt proper, so this small stretch of sky carries independently developed lore in at least three unrelated systems, a convergence explained by the belt's brightness rather than by any transmission between the traditions.
