An enigmatic, mysterious symbol in the Great Pyramid is the subject of this video by Larry Pahl, Director of the American Institute for Pyramid Research.  Linking this symbol to the logo of the Great Pyramid, the Boss, embossed on the granite leaf in the antechamber, leading to the Kings Chamber, and the Hemiunu Template, the horizontal square slice of the Pyramid at the level of the upper air shaft exits. This subject will be viewed with greater depth in future videos. Many of the drawings of the sketch in this video are from the AIP engineer Bob Crielly.  The Edgar brothers Morton and John, were tireless researcher of the Great Pyramid and much of their work is contained in "Great Pyramid Passages" which is available in many different editions on Amazon. -------
