The Greek and the Indian sculptors worked together to create a new kind of art on the northwest frontier of India, which is known as Gandhara art. Gandhara’s style of art shows a mix of various styles like Bactria, Parthian, and Greco Roman styles.
In the northwest, developed the hybrid Indo-Greek form of art where, though the themes were Indian, the depiction was heavily influenced by western art. It is popularly known as the Gandhara School of art.
The Gandhara school depicted, almost exclusively, Buddhist themes. Stucco was a popular medium in Gandhara art and the monasteries of Afghanistan were decorated with an abundance of stucco images. Gandhara artists produced images of Buddha in different postures and sizes. The large statues of Buddha at Bamiyan were one of the finest examples of Gandhara art.
The Hellenistic style is a typical style belonging to Greco-Roman art. In Hellenistic art, form sculptures are more naturalistic, and also expressive; there is an interest in depicting extremes of emotion. In the Gandhara style, we find Buddha with thick curly hairs. The halo behind the head of the image is not a prominent feature of the Gandhara style.
