Hermes Standing Upon the Back of Typhon Masonic Poster - [11'' x 17'']

From The Secret Teachings of All Ages by Manly P. Hall:

Hermes, as the personification of Universal Wisdom, is here depicted with his foot upon the back of Typhon, the vanquished dragon of ignorance and perversion. To the Egyptian initiates Typhon, the devourer of souls, signified the lower world which swallows up the spiritual nature of individual who, being imperfect, is forced to descend from the higher spheres and be reborn into the physical universe. To be swallowed by Typhon therefore signifies the process of rebirth, from which man can only release himself by vanquishing his mortal Adversary.

In on hand Hermes carries the Caduceus, a winged rod with two fighting serpents entwined about it; in the other, the immortal Emerald, upon whose surface was inscribed in raised letters the sum of philosophy. The figure wears the ancient Egyptian Masonic apron according to the pattern discovered by Belzoni, the eminent Egyptologist. The two small circles contain the forms and symbols most closely associated with Hermes. In the upper circle is the ibis, whose curious characteristics have caused it to be particularly associated with the medical art. In the initiation ceremonies the Egyptian priests wore masks in the form of the ibis head to signify that they represented the attributes of Thoth, or Hermes. The lower circle contains the dog, an animal always associated with Hermes because of its intelligence and devotion.
