The Egyptian Book of the dead by P. Le Page Renouf and Edouard Naville

2. _Akar._ The older MSS. differ hopelessly from each other as to the

name of the god. In order to understand the nature of the god ⁂⁂⁂ _Akar_, we have to imagine a _tunnel_ starting from the spot where the sun sets, and _extending through the earth_ as far as where the sun rises. Each end of the tunnel has a sphinx-like form. A human-headed lion stands at the entrance and also at the terminus. It is through the paws of this double sphinx that the galley of the Sungod enters on the Western horizon and comes out on the Eastern. In the picture Plate XV, taken from the tomb of Rameses IV, ⁂⁂, _Fair Entrance_, is written at one end of the tunnel; ⁂⁂, _Fair Exit_, at the other. As the solar bark could not be represented inside the dark tunnel, it is placed above.
