Early in the eighth century, the Confucianists made another effort to bring about a persecution of Buddhism. In 714, Yen Ts'ung argued that it was pernicious to the state, and appealed for proof to the early termination of those dynasties that had favoured it. In carrying out an edict then issued, more than 12,000 priests and nuns were obliged to return to the common world. Casting images, writing the sacred books, and building temples, were also forbidden.
At this time some priests are mentioned as holding public offices in the government. The historians animadvert on this circumstance, as one of the monstrosities accompanying a female reign.
About the beginning of the same century, Hindoos were employed to regulate the national calendar. The first mentioned is Gaudamara, whose method of calculation was called Kwang-tse-li, "The calendar of the bright house." It was used fur three years only. A better-known Buddhist
astronomer of the same nation was Gaudamsiddha. By imperial command he translated from Sanscrit, the mode of astronomical calculation called Kien-chi-shu. It embraced the calculation of the moon's course and of eclipses. His calendar of this name was adopted for a few years, when it was followed in A.D. 721 by that of the well-known Yih-hing, a Chinese Buddhist priest, whose name holds a place in the first rank of the native astronomers. The translations of Gaudamsiddha are contained in the work called K'ai-yuen-chan-king, a copy of which was discovered accidentally, in the latter part of the sixteenth century, inside an image of Buddha. It has been cut in wood more than once since that time. The part translated from Sanscrit is but a small portion of the work. The remainder is chiefly astrological. Among other things, there is a short notice of the Indian arithmetical notation, with its nine symbols and a dot for a cipher. There was nothing new in this to the countrymen of Confucius, so far as the principle of decimal notation was concerned; but it is interesting to us, whose ancestors did not obtain the Indian numerals till several centuries after this time. The Arabs learned them in the eighth century, and transmitted them slowly to Europe. Among the earlier Buddhist translations, a book is mentioned under the title of Brahmanical Astronomy," P'o-lo-men-t'ien-wen, in twenty chapters. It was translated in the sixth century by Daluchi, a native of the Maleya kingdom. Another is Ba-la-men-gih-ga-sien-jen-t'ien-wen-shwo, "An Account of Astronomy by the Brahman Gigarishi."
The date of these translations, mentioned in the "History of the Sui dynasty," can be no later than the sixth century or very early in the seventh. The same should be observed of two works on Brahmanical arithmetic, viz., Ba-la-men-swan-fa and Ba-la-men-swan-king, each containing three chapters, and a third on the calculation of the calendar,
