They had it assuredly; and it is on this “knowledge” that the programme of the Mysteries and of the series of Initiations was based: hence, the construction of the Pyramid, the everlasting record and the indestructible symbol of these Mysteries and Initiations on Earth, as the courses of the stars are in Heaven. The cycle of Initiation was a reproduction in miniature of that great series of cosmic changes to which astronomers have given the name of the Tropical or Sidereal Year. Just as, at the close of the cycle of the Sidereal Year (25,868 years), the heavenly bodies return to the same relative positions as they occupied at its outset, so at the close of the cycle of Initiation the Inner Man has regained the pristine state of divine purity and knowledge from which he set out on his cycle of terrestrial incarnation. Moses, an Initiate into the Egyptian Mystagogy, based the religious mysteries of the new nation which he created, upon the same abstract formulæ derived from this Sidereal Cycle, symbolized by the form and measurements of the Tabernacle, which he is supposed to have constructed in the Wilderness. On these data, the later Jewish High Priests constructed the allegory of Solomon’s Temple—a building which never had a real existence, any more than had King Solomon himself, who is as much a solar myth as is the still later Hiram Abif of the Masons, as Ragon has well demonstrated. Thus, if the measurements of this allegorical Temple, the symbol of the cycle of Initiation, coincide with those of the Great Pyramid, it is due to the fact that the former were derived from the latter through the Tabernacle of Moses. That our author has undeniably discovered _one_ and even _two_ of the _keys_, is fully demonstrated in the work just quoted. One has only to read it, to feel a growing conviction that the hidden meaning of the allegories and parables of both _Testaments_ is now unveiled. But that he owes this discovery far more to his own genius than to Parker and Piazzi Smyth, is also as certain, if not more so. For, as just shown, it is not so certain whether the measures of the Great Pyramid adopted by the Biblical Pyramidalists are beyond suspicion. A proof of this is to be found in the work called _The Pyramids and Temples of Gizeh_, by Mr. F. Petrie, and also in other works written quite recently to oppose the said calculations, which their authors call “biassed.” We gather that nearly every one of Piazzi Smyth’s measurements differs from the later and more carefully made measurements of Mr. Petrie, who concludes the Introduction to his work with this sentence:
