First and Second Dynasties

Due to the scarcity of wood, the two predominant building materials used in ancient Egypt were sun-baked mud brick and limestone. After the end of the Early Dynastic Period, stone became used in tombs and temples, while bricks were used even for royal palaces, fortresses, and the walls of temple precincts.

Ancient Egyptian houses were made of mud collected from the Nile River. The mud was placed in molds and left to dry in the hot sun to harden. Many Egyptian towns situated near the cultivated area of the Nile Valley have disappeared, either by flooding as the river bed slowly rose during the millennia, or the mud bricks of which they were built were used by peasants as fertilizer. Fortunately, the dry, hot climate of Egypt preserved some mud brick structures.

Large tombs of pharaohs at Abydos and Naqada, in addition to cemeteries at Saqqara and Helwan near Memphis, reveal structures built largely of wood and mud bricks, with some small use of stone for walls and floors. Stone was used in quantity for the manufacture of ornaments, vessels, and occasionally for statues. Tamarix was used to build boats such as the Abydos Boats. One of the most important indigenous woodworking techniques was the fixed mortise and tenon joint, where xed tenon was made by shaping the end of one timber to fit into a mortise (or hole) that is cut into a second timber. A variation of this joint using a free tenon eventually became one of the most important features in Mediterranean and Egyptian shipbuilding. It creates a union between two planks or other components by inserting a separate tenon into a cavity (mortise) of the corresponding size cut into each component.

Tombs and Funerary Practices

Human sacrifice was practiced as part of the funerary rituals associated with all of the pharaohs of the first dynasty. It is clearly demonstrated as existing during this dynasty by retainers being buried near each pharaoh's tomb as well as animals sacrificed for the burial. The tomb of Djer is associated with the burials of 338 individuals. The people and animals sacrificed, such as donkeys, were expected to assist the pharaoh in the afterlife. For unknown reasons, this practice ended with the conclusion of the dynasty, with shabtis taking the place of actual people to aid the pharaohs with the work expected of them in the afterlife.

Ancient Egyptian temples were aligned with astronomically significant events like solstices and equinoxes, requiring precise measurements at the moment of the particular event. Measurements at the most significant temples may have been ceremonially undertaken by the pharaoh himself.
