The historical buddha is seated with both hands in the meditation gesture, his robe covers both shoulders and forms long transversal pleats over his left arm, shorter concentric pleats on the other side. His thick curls are piled in a soft round bun on his head (ushnisha).
This later buddha’s robe has the same pleating and draping arrangement. His rounder nose and facial features depart from the Greco-Buddhist standard.
In the later phase of the Gandhara culture, buddhas often have wavy hair rather than curls, but the draping of the robe remains the same. The above has soft, plump, and even life-like, facial features and seems to be looking and smiling at us.
This is quite a different style, with the eyebrows merging into the thin lines that define the nose, a small raised urna on his forehead, semi-closed eyes.
The above has thick curls and a soft round chignon and a perfect oval face, with a broad nose and fleshy lips. His hands do the dharmacakra mudra.
