Architectural point
The traces of human activity in the Nile valley refer to the prehistoric times. The monuments of fifth millennium give the general picture of the architecture and the art. The most ancient houses of people in the Nile valley were holes and caves. Sometimes people also built sheds and tents with the help of branches and fell of animals. Later the first reed shacks appeared that were covered with clay. With the formation of the class society poor people lived in such houses during millenniums.
The houses of tribe's leaders were distinctive by their sizes first. The temples and other places for rituals holding were also organised in the big shacks. The fetish of the tribe was usually put near such shack. Later Egyptians started to use the airbricks. The yard was made in front of the building that was protected by the fence and later by the wall.
The most ancient kind of living such as hole was the model for the burials that had the oval shape. So, the first elementary kinds of houses, temples and other buildings were the same as prehistoric houses. The main principles of house, temples and tombs decoration and building were also used later in the building of Egypt during the epoch of slavery. With the invention of airbricks the first tombs in the form of rectangle appeared. Such tombs were the property of the richest people but other not so rich ones were still buried in ordinary holes. With the further division of the society, differences in the form of house and tombs appeared.
