Consulting the Oracle of Delphi Masonic Poster - [11'' x 17'']

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

While the tripod and its base as here shown differ from the description of several authors, an attempt has been made to follow as closely as possible the symbolism concealed within the allegory of the oracle. The Delphic Mysteries used the oracle as their chief symbol, and it is the spiritual esoteric mystery rather than the historical and consequently unimportant aspect with which the student of symbolism is intereded.
