The front of the great speos (fig.

90) imitates a sloping pylon crowned with a cornice, and guarded as usual by four seated colossi flanked by smaller statues.

These colossi are sixty-six feet high.
The doorway passed, there comes a first hall measuring 130 feet in length by 60 feet in width, which corresponds to the usual peristyle.

Eight Osiride statues backed by as many square pillars, seem to bear the mountain on their heads.

Beyond this come (1) a hypostyle hall; (2) a transverse gallery, isolating the sanctuary, and (3) the sanctuary itself, between two smaller chambers.
