the Sun God. On the whole, Egypt was ruled by two centers of power—legal authority and traditional authority. Legal authority constituted governing by the king, not over the people directly, but via viziers and nomarchs. Traditional authority was derived from the concept that the deities gave a king the divine right to rule as he pleased. At its heart, the Fourth Dynasty Egyptian government became organized so that only the king could direct traditional authority. The Bent Pyramid was Sneferu's first attempt at building a perfect structure, but it slopes and eventually bends to a lower angle, giving the structure a squished look. His Red Pyramid is widely considered the first true pyramid and earned its name from the reddish tint in the limestone used. The Red Pyramid was considered the first pyramid, approximately 150 years after the structures built by King Djoser. The Red Pyramid was the first to be given a solid foundation so that it was stable enough for a taller building. He is also said to be responsible for a series of pyramids built in Seila. He commissioned a total of three pyramids, but there are records that point to a fourth. Although he did not construct any of the pyramids at Giza, he is known as the king who moved the most stone and brick. A lot of Sneferu's political expeditions were to other countries to secure two things: a substantial labor force and access to a large store of materials. He traveled to Nubia and Libya for these things. His incursions in these areas allowed Sneferu to secure a large labor force, so large, in fact, that it caused huge devastation to the raided countries. He also needed cattle and other food sources to provide to the people building his pyramids. By the end of his military efforts, he managed to capture 11,000 prisoners and 13,100 head of cattle. Khufu Khufu, known to the Greek as Cheops, and Sneferu's successor—though it is unclear whether he was the biological son of Sneferu—was a widely known king. He is still known very well in present-day media, being featured in movies, novels, and television shows. His fame stems from his pyramid on the northeastern plateau at Giza, where he was buried. His mortuary temple was built on the northern end of the pyramid, which is no longer accessible due to ravages by grave robbers. Only three-dimensional reliefs
