In this presentation, Jaime Paul Lamb discusses his latest book, “Approaching The Middle Chamber: The Seven Liberal Arts in Freemasonry and the Western esoteric tradition”, in which he minutely analyzes the wealth of hidden knowledge and symbolism contained in the lecture of the Masonic Fellow Craft degree. Lamb provides a detailed historical context for each subject, while simultaneously offering unprecedented observations from the perspective of the Western Esoteric Tradition. The dizzying scope of this almost impenetrable component of Masonic ritual is deftly handled by Lamb, as he sequentially tackles subjects such as the operative and speculative dynamic in Masonry and its correlative in the Hermetic Arts, the qabalistic significance of the Brazen Pillars, the mythological symbolism underlying the ancient orders of architecture, the occult application of the five human senses and, finally, the esoteric substrata of the seven liberal arts and sciences.
