These images before destruction were located on the east side of the ceiling of the West Buddha Niche. Fifteen seated Buddhas were displayed in three rows of five. Between the Buddhas were arrays of lotus buds.
Two of the Buddhas wore suns and moons on their headdresses, the style of headdress worn by the kings of the Sassanid Empire (circa 224–651). The other three wore outer robes with the right shoulders exposed. Their aureoles and nimbuses were of various bright colors. Each Buddha was seated in full lotus position and their hands formed mudras.
