The Symbolic Meaning of the Paired Birds on the Eight Lintels on the Southern and Northern Walls of Mogao Cave 285: Questioning the Meditative Function of the Cave

Regarding the functions of Cave 285 at the Mogao Caves 莫高窟 during the Western Wei period, scholars have generally considered it a meditation cave. The main chamber has four small chambers each on the southern and northern walls, believed to serve as meditation spaces. However, a close examination of the architectural features of these eight small chambers reveals that they may have had another purpose, fundamentally different from meditation. Close visual analysis shows that the lintels of each small chamber are adorned with honeysuckle patterns, between which stand two birds forming paired bird images, with considerable variation in the types of birds. The lintel imagery of the eight small chambers in Cave 285 differs from the honeysuckle and lotus-rebirth themes commonly emphasized in the lintel designs of the main niches of contemporaneous caves that highlight the significance of the Pure Land of the Buddha. It also does not align with the flame-pattern-dominated designs seen in other niches on various faces of the central pillar during this period. This indicates a difference in symbolic meaning. At the same time, the paired birds or individual birds appear in depictions of the Pure Land on the truncated-pyramidal ceilings of caves from the same period, alongside images of honeysuckle, lotus-born beings, celestial beings, winged deities, jewels, and animals. Similarly, paired birds (such as parrots, vermilion birds, phoenixes, and bluebirds) found on the walls, heavenly gates, and screens of the Wei and Jin dynasty tombs in Dunhuang symbolize the deceased’s ascension to immortality. The frequent appearance of paired birds on lintels, doors, door frames, and walls outside the doors of tombs from the medieval period signifies the deceased’s ascension to immortality. Considering the funerary nature of the eight small chambers in Cave 285 and the symbolic meaning and development trajectory of paired birds in tombs and caves during the medieval period, the eight pairs of birds on the lintels of these small chambers were meant to aid the deceased’s soul in its ascension to immortality and rebirth in the Pure Land.
