About this time it is said that an ambassador from China came to the king of Silla at his capital city of Kyong Ju. The messenger brought various gifts, among them a substance which no one knew; it had never been seen before in Silla. It seems strange that the ambassador should not have known what he brought, but it is asserted that he was ignorant in the matter, and so the king sent to the cave—only ten miles away—and ordered the black monk to come to Kyong Ju to identify the gift. He had no trouble in recognizing it, because it was incense, common enough in Chinese Buddhism, but before unseen in Silla. He told them that when burned before an idol with prayers of faith, the god was sure to answer petitions. It happened at the moment that the king’s daughter was ill, and he begged the black monk to try the efficacy of incense and prayer. Seven days he spent in prayer before the idol and a cure was wrought. Soon afterwards Mukocha begged the king to send to China and the West for artists to come and cut figures in the rock walls of his cave, as he desired to make a chapel to the gods. The request was sent, the artists came, and it is said that they spent forty years in carving the wonderful figures which to this day adorn the walls of the little circular chapel in the mountain cave. It would require a separate lecture for me to tell you of my visit to that remarkable shrine, with its genuine treasures of art. (Plates VIII, IX.)
