The Greek names of the signs of the zodiac were adapted, and the seven day week introduced; many Greek astrological terms and some Greek mathematical terms were adopted without change. Some of the old cosmological notions, that did not interfere with the new ideas, were retained. The Greek teaching was, indeed, accepted as a whole—but the evidence points to the curious fact, that the Greek astronomy introduced is that of a period preceding Ptolemy, although Ptolemy lived in the second century of our era, and the Hindu-Greek astronomical works did not appear earlier than A.D. 400.
