THE NEOLITHIC HOUSE
With the beginning of the Neolithic Age are beginning to be built the first permanent housing. The materials are wood and clay. The skeleton of the building was made with thick branches and then knitted mesh of thin branches, which overlapped with clay layers. Inside the Neolithic home life was organized around the hearth, where the fire burns and the food is prepared. Particularly frequent is the presence inside the house, small oven with arched roof and benches made of clay beside him. The surplus of individual households were stored in large jars of unbaked clay or pits. From the Neolithic settlement of Sitagroi comes the big jar with the incised decoration project for the high season of pottery and pyrotechnology. A large part of the belongings of a Neolithic house which was made of organic materials (wood, reeds, wool, flax, skin) is permanently lost. The excavations, however, reveal to the interior of the houses and their courtyards, objects of daily life, made of clay, stone and bone, such as vases, tools, jewelry, figurines. The clay loom weights (weights) looms and spindle whorls testify to the involvement of tenants with weaving.
