connection between the Empire and the tribes on its borders that the Magians took the opportunity of preaching in China itself. Singanfu, which lies in the province of Shensi, is not far removed from the then abodes of the Turkish tribes; indeed, it was once suggested to Kaotsu, by some pusillanimous advisers, that he should remove his capital to some safer spot in the province of Honan, where he would be free from the danger of incursions from the barbarians.
The year of Shotoku's death was also the year of the Hejirah, the year in which Mohammed fled to Medina and announced his divine mission to the astonished world. Ten years later, Izdegerd, King of Persia, was fighting for his very existence against the victorious Arabs who had gone forth conquering and to conquer, and by the year 640 the whole of Persia, with Merv, Balkh, Herat, everything as far as the Indus and the Oxus, had submitted to the sword of the new-born enthusiasm.

They were loyal to the country of their adoption, as well they might be; that country was now in distress, and was looking to China for help; a Christian mission in China might be productive of much good, both spiritually and politically. The mission was, therefore, sent; it arrived at Singanfu in 636, and was well received by the Emperor and his successors, some of whom issued edicts in favour of the faith, or gave money for building "temples of felicity," as they were called, whilst one went so far in his patronage that,
