About the Eastern Stairway
This staircase leads from the Offering Table Hall to the roof of the temple, where the rites of the Opening of the Year – Wapat Ranapat were performed. The living statue of the god Horus was carried in procession with the other divine statues of his Ennead at the temple to see the sun at dawn of the opening of the year. Once rites are performed, the divine statues are again carried in procession down the western stairway with Hathor in her form of the uraeus and all are returned to their shrines. The eastern stairway measures 15 feet (5.334 m) by 12 feet (4.267 m). Inscribed on the walls are images of priests and the Pharaoh carrying the divine statues to the roof for the Wapat Ranapat rites.
