Explanation:

While the earlier Buddhists had used only symbols to depict the Buddha, the Mathura school became the first to make faces and figures of the Buddha.Folklores such as the Jatakas were drawn out in long panels on rock faces. Besides the images of Buddha, which were made in large numbers, statues of Mahavira were also produced.
Learning: Mathura, which was the centre of the indigenous school of art, was also influenced by the invasions. A number of images from here of terracotta and red sandstone, which have definite Saka-Kushan influence, have survived. The most famous is the headless statue of Kanishka from Mathura.
