Construction Methods of the Pyramids of the IV Dynasty 1. Introduction In ancient Egypt, a civilization in the northeastern part of Africa, there are many famous large buildings. Among these, pyramids are unique buildings that are hard to find elsewhere in the world. Pyramids were made mainly in a period called the Old Kingdom, as the remains that prove this, many of which are still preserved in the desert of the west bank of the Nile River in the vicinity of Cairo. Pyramids are built near the tomb of the king of each dynasty called Pharaoh, and in general, each pyramid is a building with a stone-conical mountain shape. The pyramid has three or four steps with the top flattened. The inclination of the surface of the pyramid building differs slightly depending on the period of production, but this inclination is also stored with almost high precision throughout the pyramid (Tasellari & Kaiku, 2013). The pyramid is a structure-ruled building that has lasted over 4,000 years and that there is a considerable amount of experimental evidence here that reveals high construction technology. The pyramids are gathered mainly at three locations. One is on the west bank of Cairo in the north of the Nile Delta, in the vicinity of Giza. At this ancient era capital called Men-Nefer, Pharaoh of the Fourth Dynasty arranged the marble and built a pyramid. The pyramid is one of the largest and most monumental pyramids ever, and its complete view is symbolic of the Egyptian pyramids. In recent years, new methods of study and research have been deepened through the use of scientific analysis, and knowledge of the building of pyramids has been advanced to engineering analysis. This study uses various data gathered by such advanced research methods, considering the historical background around the pyramid, and examining the method by which the pyramids of the Fourth Dynasty were inbuilt based on the history of the time. 2. Historical Context of the IV Dynasty The orientation paper has as its primary goal an examination of the construction methods employed in the building of the Pyramids of the IV Dynasty. Before the building of the IV Dynasty pyramids, there was centuries of experimental pyramid construction. The IV Dynasty pyramids refined the techniques of earlier pyramids by constructing a steeper angle, 52°, and incorporating underground chambers or
