"Sisig (a god of dreams), the son of Utu, will provide light for him in the nether world, the place of darkness. When a funerary statue is made in honour of someone, whoever they may be, for future days, mighty youths [...] will form a semicircle at the door-jambs and perform wrestling and feats of strength before them. In the month Nenejar, at the festival of the ghosts, no light will be provided before them without him (i.e. Gilgamesh)."
