Before the 15th century, Tibetan metal sculptures normally depict the historical buddha with the right arm and shoulder bare, and only the hem of the under garments is occasionally showing. The above wears a patched robe with a richly incised hem that covers both shoulders and an undergarment tightly gathered below the breast.
As from the 15th century, it is not unusual for the right shoulder to be covered but the arm remains bare.
The hem of this sanghati is incised with a rice grain motif traditional in Nepal. The inner garment is loosely gathered around the right breast.
The turquoise-inlaid extremity of the robe over the left shoulder is a rare feature, and so are the turquoise-inlaid rosettes over the ears. Both the outer and the inner garment of this buddha have a richly incised hem.
Another unsusual feature: one end of the sanghati covers the right shoulder in cascades of folded cloth, right down to the elbow (before being tucked under the breast as before). The lower part is loosely gathered over and under the legs.
Shakyamuni holds an alms bowl in his left hand. There is a small vajra sceptre in front of him. His right shoulder is tightly wrapped with part of his robe.
Around the 16th century, the cloth often barely covers the right shoulder.
As a result, it is no longer tucked under the breast.
Sometimes, the emphasis is placed on the abundant draping around the legs.
