. As a result of the poor construction manner and the use of low quality materials, coupled with the activity of grave robbers, the pyramid has now been reduced to a tall ruined mound. The decision to use inferior materials may have arisen from economic and practical considerations. In particular, Faiyum has abundant clay deposits which could be sourced. Before the pyramid, on its east side, lay the mortuary temple that carried its own name independent of the pyramid. In the Old Kingdom, mortuary complexes were given a single name. Amenemhat I broke with this tradition instead choosing to provide names for the individual components. The temple was named 'High [rises up] Amenemhat's beauty'. The temple was built on a lower level than the pyramid – perhaps in reference to the terraced mortuary temple of Mentuhotep II – and was of a smaller size compared against Old Kingdom temples. There are few remains of the temple preventing a detailed reconstruction, and only its courtyard has been properly investigated. It appears that the temple was rebuilt during the reign of Senusret I, as attested to by inscriptions bearing his name. There is no evidence of a cult pyramid extant, though the causeway and valley temple – which has not been investigated and is now buried under a local cemetery – have been identified. Within its perimeter wall are the grave sites of family members and officials. These include his mother, Nefret; wife, Neferitatjenen; and a daughter, Neferu; along with a vizier, Intefiqer. Beneath the pyramid, entered from the north chapel, is the substructure. The north chapel contained a red granite false door, behind which lay the descending corridor. The pink granite lined corridor plugged with blocks leads to a square chamber with a shaft in its centre that leads to the burial chamber. This chamber has filled with ground water and has never been accessed. Assassination Two literary works dating from the end of the reign give a picture about Amenemhat I's death. The Instructions of Amenemhat were supposedly counsels that the deceased king gave to his son during a dream. In the passage where he warns Senusret I against too great intimacy with his subjects, he tells the story of his own death as a reinforcement: This passage refers to a conspiracy in which Amenemhat was killed by his own guards, when his son and co-regent Senusret I was leading
