A temple has added sacredness in China according as its foundation is on a spot originally chosen or honored by a representative of Heaven as a threshold of a place of worship. Thus Tai Shan, or the “Great Mount,” in the province of Shantung, China, is mentioned in the Shoo King, or Book of Records, as the site of the great Emperor Shun’s altar of sacrifice to Heaven, 2254 B.C., or, say, three centuries before the time of Abraham. On this holy mountain, as the earliest historic foundation of Chinese worship, “is the great rendezvous of devotees, every sect has there its temples and idols, scattered up and down its sides;” and great multitudes come thither to worship from near and far.[450] This idea shows itself in modern discoveries among the ruins of ancient Greece. It appears that when Pericles (437 B.C.) began his building of the new Propylæa on the Acropolis, he would have cleared away the remains of such ancient sacred structures as stood within its outline. “The plan of Mnesikles the architect was very simple, and is still clear enough, though it was never fully carried out.” “That the original plan of Mnesikles had undergone modifications was long ago seen by every architect who made the Propylæa matter of serious study.” Dr. Dörpfeld thinks he has discovered how the plan was modified, and why. The enforced departure from the original plan seems to have been because that plan involved the destruction of shrines on an earlier foundation, with a threshold that might not be moved. The gate of Cimon, with its “statue of some guardian god of the gate,–it may be Hermes Propylaios himself,”–was within that outline, and also other sacred sites. “Against such intrusion it is very likely the priesthood rose and protested, and, before even the foundations were laid, he had to give up, at least for the time, the whole of the southeast hall, and a part of the southwest wing.” This conclusion is the result of recent investigation by careful scholars, and it is in accordance with the ascertained fact that in primitive thought an original foundation for a temple or shrine is counted sacred for all time as the foundation there for such a place of worship, not to be swept away or ignored in any rebuilding or new building.[451]
