A corresponding suite on the eastern side of the roof depicts the lunar festival of Khoiakh in which an 'Osiris bed' was filled with earth and grain seed as part of an important fertility rite. The walls of the first room show scenes of the burial goods of Osiris, including his canopic jars and on the ceiling Nut is shown with other astronomical figures. On the other half of the ceiling is a plaster copy of the famous 'Dendera Zodiac', representing the cospic aspect of the Osiris mysteries. The original is now in the Louvre in Paris. The inner room depicts scenes from the Osiris myth, similar to that of the western suite as well as reliefs of cosmic importance.
