Schist
Sakra is considered to be a protector of Sakyamuni. The figure looks to one side and is characterized particularly by wavy hair and a heavy beard. The flat-topped crown identifies the figure as Sakra rather than Vajradhara - who is usually depicted carrying a similar vajra. The detached right hand is resting upon the serpentine foliar motif of the balustrade. A buckled cloak covers the shoulders of Sakra with double incised lines used to represent folds in the garment beneath that commonly seen in the late Gandharan period.
