Brahman astronomy owed much to the Greeks, and what the Buddhists were to the architecture of northern India, that the Greeks were to its sculpture. Greek faces and profiles constantly occur in ancient Buddhist statuary, and enrich almost all the larger museums in India. The purest specimens have been found in the North-west frontier province (the ancient Gandhara) and the Punjab, where the Greeks settled in greatest force. As we proceed eastward from the Punjab, the Greek type begins to fade. Purity of outline gives place to lusciousness of form. In the female figures, the artists trust more and more to swelling breasts and towering chignons, and load the neck with constantly accumulating jewels. Nevertheless, the Grecian type of countenance long survived in Indian art. It is entirely unlike the present coarse conventional ideal of sculptured beauty, and may even be traced in the delicate profiles on the so-called sun temple at Kanarak, built in the 12th century A.D. on the remote Orissa shore. The Maurya Dynasty. Chandragupta (q.v.) was one of the greatest of Indian kings. The dominions that he had won back from the Greeks he administered with equal power. He maintained an army of 600,000 infantry, 30,000 horsemen, 36,000 men with the elephants, and 24,000 men with the chariots, which was controlled by an elaborate war-office system. The account given of his reign by Megasthenes makes him better known to us than any other Indian monarch down to the time of Akbar. In 297 B.C. he was succeeded by his son, Bindusara, who is supposed to have extended his dominions down to Madras. In 272 B.C. he in turn was succeeded by Asoka, the Buddhist emperor, the religious side of whose reign has already been described. Asoka's empire included the greater part of Afghanistan, a large part of Baluchistan, Sind, Kashmir, Nepal, Bengal to the mouths of the Ganges, and peninsular India down to the Palar river. After Asoka the Mauryas dwindled away, and the last of them, Brihadratha, was treacherously assassinated in 184 B.C. by his commander-in-chief, Pushyamitra Sunga, who founded the Sunga dynasty.
