Many of the stylistic elements in the representations of the Buddha point to Greek influence: the Greek himation (a light toga-like wavy robe covering both shoulders: Buddhist characters are always represented with a dhoti loincloth before this innovation), the halo, the contrapposto stance of the upright figures, the stylized Mediterranean curly hair and top-knot apparently derived from the style of the Belvedere Apollo (330 BC), and the measured quality of the faces, all rendered with strong artistic realism (See: Greek art). Some of the standing Buddhas (as the one pictured) were sculpted using the specific Greek technique of making the hands and sometimes the feet in marble to increase the realistic effect, and the rest of the body in another material.
