His tomb lies close to Khufu's pyramid. Biography Hemiunu was a son of prince Nefermaat and his wife, Itet. He is a grandson of Sneferu and a nephew of Khufu, the Old Kingdom pharaoh. Hemiunu had three sisters and many brothers. In his tomb, he is described as a hereditary prince, count, sealer of the king of Lower Egypt (jrj-pat HAtj-a xtmw-bjtj), and on a statue found in his serdab (and now located in Hildesheim), Hemiunu is given the titles: king's son of his body, chief justice, and vizier, greatest of the five of the House of Thoth (sA nswt n XT=f tAjtj sAb TAtj wr djw pr-DHwtj). Tomb Hemiunu's tomb lies close to Khufu's pyramid and contains reliefs of his image. Some stones of his badly damaged mastaba () are marked with dates referring to Khufu's reign. His statue can be found at the Pelizaeus Museum, Hildesheim, Germany. This statue is scheduled to be loaned for the opening of the Grand Egyptian Museum in late 2022. His statue was found in the walled-up serdab of Hemiunu's mastaba by archaeologist Hermann Junker in March 1912. Ancient looters had ransacked the mastaba in their quest for valuable items and the wall to the serdab had a child-sized hole cut into it. The robber forcefully gouged out the statue's precious inlaid eyes and gold castings, in the process the right arm was broken and the head severed. The head has been restored, using a relief of Hemiunu as a guide for the nose's profile. The seated statue is well-preserved, apart from the damage mentioned above, and is notable for its realism, not found in ancient Egyptian art
