Bones in the secondary burial were arranged without respect for anatomical order; it is plausible to assume that the distribution process was the result of symbolic rituals that indicated the changing of the deceased's role by incorporating him or her into the group of royal ancestors. Pottery vessels were deposited next to the secondary burial remains; they were fixed on top of food offerings meant as a food supply for the dead, giving evidence for the performance of Kispu (nourishing and caring for one's ancestor through a regular supply of food and drink). Hundreds of pilled vessels provide evidence that the living participated and dined with their ancestors, venerating them. Pfälzner argues for a third burial process which he calls the tertiary burial; the eastern chamber of the hypogeum was used as an ossuary where human remains and animal bones left from the Kispu were mixed and pilled. Pfälzner conclude that bones left in that chamber were deposited there because they had become useless in funerary rituals, thus the chamber was their final resting place. Bones in the eastern chamber were stored with no respect for the unity of an individual, indicating that the persons buried were now part of the collective group of ancestors; this did not mean that the individuals were no longer cared for, as the many bowls in the chamber indicate the continuation of food offerings to those ancestors.
