HINDU PERIOD The external history of India may be considered to begin with the Greek invasion in 327 B.C. Some indirect trade between India and the Levant existed from very ancient times. Homer was acquainted with tin and other articles of Indian merchandise by their Sanskrit names ; and a long list has been made of Indian products mentioned in the Bible. In the time of Darius the valley of the Indus was a Persian satrapy. But the first Greek historian who speaks clearly of India was Hecataeus of Miletus B.c.) ; the knowledge of Herodotus (45o B.c.) ended at the Indus; and Ctesias, the physician (401 B.c.), brought back from his resi dence in Persia only a few facts about the products of India, its dyes and fabrics, its monkeys and parrots. India to the east of the Indus was first made known in Europe by the historians and men of science who accompanied Alexander the Great in 327 B.C. Their narratives, although now lost, are condensed in Strabo, Pliny and Arrian.
During his two years' campaign in the Punjab and Sind, Alex ander captured no province, but he made alliances, founded cities and planted garrisons. He had transferred much territory to chiefs and confederacies devoted to his cause, and every petty court had its Greek faction. At Taxila (Dehri-Shahan) and Nicaea (Mong) in the northern Punjab, at Alexandria (Uchch) in the southern Punjab, at Patala (Hyderabad) in Sind, and at other points along his route, he established military settlements of Greeks or allies. A large body of his troops remained in Bactria; and, in the par tition of the empire which followed Alexander's death in 323 B.e., Bactria and India eventually fell to Seleucus Nicator, the founder of the Syrian monarchy.
Previous to the time of Megasthenes the Greek idea of India was a very vague one ; and it was he who first opened up the land to the western world. He describes the classification of the people, dividing them, however, into seven castes instead of four, namely, philosophers, husbandmen, shepherds, artisans, soldiers, inspectors and the counsellors of the king. The philosophers were the Brahmans, and the prescribed stages of their life are indicated. Megasthenes observes with admiration the absence of slavery in India, the chastity of the women, and the courage of the men. In valour they excelled all other Asiatics; they required no locks to their doors; above all, no Indian was ever known to tell a lie. Sober and industrious, good farmers and skilful artisans, they scarcely ever had recourse to a lawsuit, and lived peaceably under their native chiefs. The kingly government is portrayed almost as described in Manu, with its hereditary castes of councillors and soldiers. Megasthenes mentions that India was divided into one hundred and eighteen kingdoms; some of which, such as that of the Prasii under Chandragupta, exercised suzerain powers.
The Brahmanism of northern India was destined to be pro foundly influenced by the two powerful monarchies which sprung up toward the close of the fourth century B.C. On the east, in the Gangetic valley, Chandragupta firmly consolidated the dynasty which during the next century produced Asoka (264-228 or 227 B.C.), and established Buddhism throughout India. On the west, the Seleucids diffused Greek influences, and sent forth Graeco Bactrian expeditions to the Punjab. Antiochus Theos (grandson of Seleucus Nicator) and Asoka (grandson of Chandragupta), who ruled these two monarchies in the 3rd century B.C., made a treaty with each other (256). In the next century Eucratides, king of Bactria, conquered as far as Alexander's royal city of Patala, and possibly sent expeditions into Cutch and Gujarat, 181-161 B.C. Of the Graeco-Indian monarchs, Menander advanced farthest into north-western India, and his coins are found from Kabul, near which he probably had his capital, as far as Muttra on the Jumna. The Buddhist dynasty of Chandragupta affected the religion of northern India from the east ; the Seleucid empire, with its Bactrian and later offshoots, influenced the science and art of Hindustan from the west.
