Ancestors were worshiped in Qatna; the royal hypogeum provided a large amount of data concerning the cult of ancestor worshiping and the practices associated with it. Two kinds of burials are distinguished; a primary burial intended to transport the dead into the netherworld, and a secondary burial that was intended to transform the deceased into their ultimate form: an ancestor. The royal hypogeum provides hints at the different rituals taking place during a secondary burial; a noticeable character is that skeletons were not complete, and no skulls are found for the majority of secondary burial remains. There is no evidence that skulls decayed as they would have left behind teeth, of which very few were found, indicating that the skulls were removed to be venerated in another location.
