The Dimensions of the Lodge, our Brethren of the York Rite say, "are unlimited, and its covering no less than the canopy of Heaven." "To this object," they say, "the mason's mind is continually directed, and thither he hopes at last to arrive by the aid of the theological ladder which Jacob in his vision saw ascending from earth to Heaven; the three principal rounds of which are denominated Faith, Hope, and Charity; and which admonish us to have Faith in God, Hope in Immortality, and Charity to all mankind." Accordingly a ladder, sometimes with nine rounds, is seen on the chart, resting at the bottom on the earth, its top in the clouds, the stars shining above it; and this is deemed to represent that mystic ladder, which Jacob saw in his dream, set up on the earth, and the top of it reaching to Heaven, with the angels of God ascending and descending on it. The addition of the three principal rounds to the symbolism, is wholly modern and incongruous. The ancients counted seven planets, thus arranged: the Moon, Mercury, Venus, the Sun, Mars, Jupiter, and Saturn. There were seven heavens and seven spheres of these planets; on all the monuments of Mithras are seven altars or pyres, consecrated to the seven planets, as were the seven lamps of the golden candelabrum in the Temple. That these represented the planets, we are assured by Clemens of Alexandria, in his Stromata, and by Philo Judaeus. To return to its source in the Infinite, the human soul, the ancients held, had to ascend, as it had descended, through the seven spheres. The Ladder by which it reascends, has, according to Marsilius Ficinus, in his Commentary on the Ennead of Plotinus, seven degrees or steps; and in the Mysteries of Mithras, carried to Rome under the Emperors, the ladder, with its seven rounds, was a symbol referring to this ascent through the spheres of the seven planets. Jacob saw the Spirits of God ascending and descending on it; and above it the Deity Himself. The Mithraic Mysteries were celebrated in caves, where gates were marked at the four equinoctial and solstitial points of the zodiac; and the seven planetary spheres were represented, which souls needs must traverse in descending from the heaven of the fixed stars to the elements that envelop the earth; and seven gates were marked, one for each planet, through which they pass, in descending or returning. We learn this from Celsus, in Origen, who says that the symbolic image of this passage among the stars, used in the Mithraic Mysteries, was a ladder reaching from earth to Heaven, divided into seven steps or stages, to each of which was a gate, and at the summit an eighth one, that of the fixed stars. The symbol was the same as that of the seven stages of Borsippa, the Pyramid of vitrified brick, near Babylon, built of seven stages, and each of a different color. In the Mithraic ceremonies, the candidate went through seven stages of initiation, passing through many fearful
