After a moment's reflection I decided not to retrace my steps. Away from the draught I would have no landmarks, for the roughly level rock floor was devoid of distinctive configurations. If, however, I followed up the strange current, I would undoubtedly arrive at an aperture of some sort, from whose gate I could perhaps work round the walls to the opposite side of this Cyclopean and otherwise unnavigable hall. That I might fail, I well realized. I saw that this was no part of Khephren's gateway temple which tourists know, and it struck me that this particular hall might be unknown even to archaeologists, and merely stumbled upon by the inquisitive and malignant Arabs who had imprisoned me. If so, was there any present gate of escape to the known parts or to the outer air?
