c15.s1.4

Soon after the beginning of the Christian era the traditional astronomical system in India was largely discarded, and the system in vogue in the Greek schools was imported and assimilated. In the *Pañcha Siddhāntikā* of Varāha Mihira we, possibly, have summaries of two western books—the *Paulisa* and *Romaka Siddhāntas*, but, quite apart from this, there is abundant evidence to show, not only Greek influence, but, Greek domination. The representative Indian work, that exhibits the astronomy of this period, is the *Sūrya Siddhānta*. In its original form this work was probably composed about A.D. 400, and the recension now in use about A.D. 1100. Since then very little attempt at advance has been made. The orthodox still accept the *Sūrya Siddhānta* as authoritative, and other works are not essentially different.
