Huns, when the art of Gandhara, becomes essentially extinct. When Xuanzang visited northwestern India in AD, he reported that Buddhism had drastically declined, and that most of the monasteries were deserted and left in ruins. Southern influences Art of the Shunga Examples of the influence of Hellenistic or Greco-Buddhist art on the art of the Shunga Empire (183-73 BC) are usually faint. The main religion, at least at the beginning, seems to have been Brahmanic Hinduism, although some late Buddhist realizations in Madhya Pradesh as also known, such as some architectural expansions that were done at the stupas of Sanchi and Bharhut, originally started under King Ashoka. Art of Mathura The representations of the Buddha in Mathura, in central northern India, are generally dated slightly later than those of Gandhara, although not without debate, and are also much less numerous. Up to that point, Indian Buddhist art had essentially been aniconic, avoiding representation of the Buddha, except for his symbols, such as the wheel or the Bodhi tree, although some archaic Mathuran sculptural representation of Yaksas (earth divinities) have been dated to the 1st century BC. Even these Yaksas indicate some Hellenistic influence, possibly dating back to the occupation of Mathura by the Indo-Greeks during the 2nd century BC. In terms of artistic predispositions for the first representations of the Buddha, Greek art provided a very natural and centuries-old background for an anthropomorphic representation of a divinity, while on the contrary "there was nothing in earlier Indian statuary to suggest such a treatment of form or dress, and the Hindu pantheon provided no adequate model for an aristocratic and wholly human deity" (Boardman). The Mathura sculptures incorporate many Hellenistic elements, such as the general idealistic realism, and key design elements such as the curly hair, and folded garment. Specific Mathuran adaptations tend to reflect warmer climatic conditions, as they consist in a higher fluidity of the clothing, which progressively tend to cover only one shoulder instead of both. Also, facial types also tend to become more Indianized. Banerjee in Hellenism in ancient India describes "the mixed character of the Mathura School in which we find on the one hand, a direct continuation of the old Indian art of Bharhut and Sanchi and on the other hand, the classical influence derived from Gandhara". The influence of Greek art can be felt beyond Mathura, as far as Amaravati on the East coast
