there was indeed an eclipse on the day stated, but before the rising of the sun at the then capital of China[1]. My friend, the Rev. Dr. Chalmers of Canton, not knowing anything of the examination made by Largeteau, undertook to verify the eclipse in 1861, and found that while the year, the month, and the day, as given by Gaubil, were correct, the eclipse had taken place during the night, and could not have been seen by the Chinese astronomers. The eclipse mentioned in the document of the Shû cannot therefore be used at present to confirm the received chronology of China; but I am unwilling to give it up entirely. M. Biot says that, 'Notwithstanding the failure of the attempt of Largeteau to verify the eclipse, the hope of yet finding it in some one of the years of the twenty-second century before our era is not entirely lost. We ought to wait till the further perfecting of the lunar tables brings us new lights, by means of which we can form a surer judgment.'
6. We come to the earliest period of Chinese history of which the Shû makes more than a cursory mention,—that of Yâo and Shun. It says that Shun was The period of Yâo and Shun. thirty years on the throne with Yâo, and that, fifty years after, he died and went on high. We learn from it also that it was in the seventieth year of his reign that Yâo sought for another to relieve him of the toils of government. The period covered by the two therefore is 150 years, which both the schemes of chronology accept. Adding two years of mourning between Shun's death and Yü's accession to the throne, we have B.C. 2357 as the first year of Yâo.
In the Canon of Yâo, when that personage is giving directions to his astronomers how to determine the equinoxes and solstices, he tells them that at the vernal equinox they would find the star in Niâo, and at the autumnal in Hsü; at the summer solstice, the star in Hwo, and at the winter in Mâo. It has always been assumed by Chinese scholars that when Yâo said, 'The star of mid-spring is- ↑ Etudes sur l'Astronomie Indienne et sur l'Astronomie Chinoise, pp. 376–382.
