In the period following Asoka's death Buddhism suffered a temporary eclipse. Pushyamitra who in 184 B.C. overthrew the Mauryas and established the Sunga dynasty was a patron of the Brahmans. Târanâtha describes him[175] as a ferocious persecutor, and the Divyâvadâna supports the story. But the persecution, if it really occurred, was probably local and did not seriously check the spread of Buddhism, which before the time of Kanishka had extended northwards to Bactria and Kashmir. The latter territory became the special home of the Sarvâstivâdins. It was in the reign of Pushyamitra that the Græco-Bactrian king Menander or Milinda invaded India (155-3 B.C.) and there were many other invasions and settlements of tribes coming from the north-west and variously described as Sakas, Pahlavas, Parthians and Yavanas, culminating in the conquests of the Kushans. The whole period was disturbed and confused but some general statements can be made with considerable confidence. From about 300 B.C. to 100 A.D. we find inscriptions, buildings and statues testifying to the piety of Buddhist and Jain donors but hardly any indications of a similar liberality to Brahmans. In the second and third centuries A.D. grants of land to Brahmans and their temples begin to be recorded and in the fourth century (that is with the rise of the Gupta Dynasty) such grants become frequent. These facts can hardly be interpreted otherwise than as meaning that from 300 B.C. to 100 A.D. the upper classes of India favoured Buddhism and Jainism and did not favour the Brahmans in the same way or to the same extent. But it must be remembered that the religion of the Brahmans continued throughout this period and produced a copious literature, and also that the absence of works of art may be due to the fact that their worship was performed in sacrificial enclosures and that they had not yet begun to use temples and statues. After the first century A.D. we have first a gradual and then a rapid rise in Brahmanic influence. Inscriptions as well as books indicate that a linguistic change occurred in the same period. At first popular dialects were regarded as sufficiently dignified and current to be the medium for both scripture and official records. Sanskrit remained a thing apart--the peculiar possession of the Brahman literati. Then the popular language was Sanskritized, the rules of Sanskrit grammar being accepted as the standard to which it ought to conform, though perfect conformity was impracticable. In much the same way the modern Greeks try to bring Romaic into line with classical Greek. Finally Sanskrit was recognized as the proper language for literature, government and religion. The earliest inscriptions[176] in correct Sanskrit seem to date from the second century A.D. Further, the invaders who entered India from the north-west favoured Buddhism on the whole. Coins indicate that some of them worshipped Śiva[177] but the number and beauty of Buddhist
