Explanation:

Gandhara School of art had also developed in first century AD along with Mathura School during reign of Kushana emperor Kanishka. Both Shakas and Kushanas were patrons of Gandhara School, which is known for the first sculptural representations of the Buddha in human form. The art of the Gandhara school was primarily Mahayana and shows Greco-Roman influence. Gandhara School was based on Greco-Roman norms encapsulating foreign techniques and an alien spirit. It is also known as Graeco-Buddhist School of art.  The foreign influence is evident from the sculptures of Buddha in which they bear resemblance to the Greek sculptures. Grey sandstone (Blue-grey Mica schist to be precise) is used in Gandhara School of Art. Gandharan Buddha image was inspired by Hellenistic realism, influenced by Persian, Scythian, and Parthian models.  In contrast with Mathura School, the Gandhara School images are known for their anatomical accuracy, spatial depth, and foreshortening. In this art, Buddha’s curls were altered into wavy hair. The head of the Buddha matched very much with Greek God Apollo.
