According to the testimony of various writers upon this subject, there are still extant, not alone in oriental countries, but in Ireland and Scotland as well, numerous excavations or apertures in the rocks which by an early race were used for the same purpose. Through the misconception, bigotry, and ignorance of the Roman Catholic missionaries in Ireland, these openings were designated as the "Devil's Yonies." Although these emblems typified the original conception of one of their most sacred beliefs, namely, the "new birth," still they were "heathen abominations" with which the devotees of the new (?) faith must not become defiled. The people who executed these imperishable designs, and who have left in the British Isles innumerable evidences of their religious beliefs, are supposed by some writers to belong to a colony which, having been expelled from Persia on account of their peculiar religious beliefs, settled in the "White Island," the "Island of the Blessed." This subject will, however, be referred to later in this work. When we closely examine the facts connected with the evolution of religion, there can be little doubt that the Persians laid the foundation for that great moral and intellectual awakening which a century or two later is represented by Confucious, Gotama Buddha, and Pythagoras. From the Persians, doubtless Jew and Gentile alike received the little leaven of spirituality which in later ages crept into their gross conception of a Deity. By the Persians, the Hindoos, and other nations of the East, it was believed that the end of each cycle of six hundred years, at which time a new sun or savior was to come, would mark a new era of religious development. At the close of each of these cycles it was devoutly expected that the "golden age" of the past would be restored, and that mankind would again be freed from the ills which had overtaken them. As many of these cycles had passed, numerous deliverers, saviors, or solar incarnations had appeared in India, Gotama Buddha having been the ninth. In the East, about six or seven hundred years before the birth of Christ, not only one savior or prophet but three or four of them appeared.
