Although the two statues are damaged, they are similar enough that their details supplement each other. They were listed as Treasure No. 220 in 1963.
Both figures are seated in full lotus position with damaged hands that scholars believe were in bodhyangi (wisdom fist) mudra. The mandorla behind them are slightly different. One mandorla shows a triad of seated Buddhas riding on clouds and a series of single Buddhas down the sides, while the other mandorla has three sets of triads. Apart from these details, the other elements are similar, a lotus nimbus in the center and the rest of the space filled with flames.
The column that supports the lotus seat of the Buddha is decorated with carvings of Buddhas and Bodhisattvas. The base of the throne is also slightly different, with one decorated with a mountain censer and lions, and the other filled with doors and lions.
