Here, again, we learn from the book of Henoch, that the subterranean building that he constructed in the land of Canaan in the bowels of the mountain, with the help of his son Mathusalath, was in imitation of the nine vaults that were shown to him by the Deity, each apartment being roofed with an arch, the apex of which formed a key-stone with mirific characters inscribed on it. Each of the nine letters, we are told, represented one of the nine names traced in characters emblematical of the attributes of Deity. Henoch then constructed two triangles of the purest gold, and traced two of the mysterious characters on each. One he placed in the deepest arch; the other he entrusted to Mathusalath, _to whom he communicated important secrets._ [Illustration] Thou art Bait (the soul); thou art Athor, one of the Bia; and thou art Akori. Hail, father of the world! hail, triform God! The triangular arches appear, therefore, as landmarks of one and the same doctrine, practised in remote times, in India, Egypt, Chaldea, Greece, Etruria and Central America. In the ceilings of the rooms situated at the north and south extremities of the building are carved in peculiar and regular order, in deep intaglio, semispheres, ten centimeters in diameter, intended to represent the stars that at night so beautify the firmament. Inside of the triangle formed at each end of said rooms by the converging lines of the arch are also several of these semispheres—those in the north room form a triangle (Fig. 1); while those in the south room, five in number, figure a trapezium (Fig. 2); with one of these half spheres in the middle. [Illustration: FIG. 1.] [Illustration: FIG. 2.] The middle chamber is now devoid of decorations of any sort. Its length, _seven_ meters, is to-day the only vestige which remains to indicate that in it, in former times, were practised rites and ceremonies pertaining to the third degree of initiation. This chamber could be reached by walking on the narrow terrace round the building; but I feel certain that those whose privilege it was to assemble within its walls, got to it from the west side. [Illustration] There was a stairway nine metres wide, beautifully ornamented, leading from the court yard adjoining the priests' palace, to the entrance of the sanctuary. Thence another small stairway 2m. 40c. wide, situated on the north side of the sanctuary, led to the upper terrace, to the roof of that monument, and to the middle chamber. The access to the north and south rooms was by a grand stairway of ninety-six steps, each 20cm. high, that led to the upper terrace surrounding the whole edifice. This stairway, situated on the east side of the mound, is fourteen metres (45 feet 6 inches) wide, and, like that on the east side, so steep as to require no little practice and care to ascend and descend its narrow steps with comparative safety and ease.
