An Osiris bed is the recessed image of the deceased image of the god in the brick-shaped 'bed' would be filled with soil and seeds (barley or emmer wheat) to germinate and grow during the festival of Khoiak. This was the climax of the four month Nile inundation season, when the death and resurrection of Osiris were commemorated and the fruitfulness of the land was ensured for another year. The corn Osiris was then ritually buried.
From western Thebes, late period, c.500 BC.
