The settlements discovered in Bir Abu Matar belong to the
Chalcolithic period,
Beersheba Culture, and can be divided into 3 distinct
settlement phases, each with its own particular
architecture: the earliest settlers built underground dwellings, dug in the soft
loess. Later, when some of these homes collapsed - their ceilings had caved in - new, semi-underground houses were built on top of the old ones. In the 3rd and final phase the settlers built their homes completely above ground. During all phases, houses usually contained one large central room connected to up to 10 other rooms located around it. The population had never exceeded 200 people. Bir Abu Matar was part of a system of settlements that had economical connections with each other. In addition to
subsistence farming, each settlement tended to specialize in one particular branch of industry: in Bir Tzafad it was
ivory carving and in Bir Abu Matar -
copper smelting and the production of copper instruments, artifacts and
jewelry.
Subterranean phase Initially, the houses were made of one large rectangular room accessible by a horizontal entry tunnel. The ceilings of those houses soon collapsed, and the locals began building houses of a different type: those usually contained several round or oval rooms, the size of which was about 3.5 x 4.0 meters. These houses were dug relatively deep under the surface, leaving a thick layer of soil between their ceiling and the ground above. All the rooms were connected by tunnels, at least one of which led to a vertical entry shaft, leading to the surface. These shafts sometimes had staircases built in them or carved out of the wall. Around the top of such entry shafts the residents usually dug a shallow depression that served as a yard. Most of the rooms contained storage spaces dug in their floors which the residents kept covered with large stone slabs. Charred grains of food crops were discovered in some of them. Many rooms also contained pits of different sizes, some of which had been sealed with plaster, which indicates that they had been used for storing water. Most of the floors of these rooms were found covered in ash,
pottery sherds, animal bones, etc., indicating these houses were used as a living space. Houses of this type are best suited for a climate where the days are hot and the nights are cold, since the temperature in them remains even throughout the day. These houses had ventilation shafts which mostly drew air from the western side of the settlement. Many small ceramic bowls were discovered during excavations - those were probably used as primitive lamps, since these subterranean houses had been immersed in permanent darkness and needed to be artificially illuminated. Most of these underground houses had been abandoned by their owners. Houses with sealed storage spaces containing neatly arranged house appliances were discovered on the site. Their rooms had been sealed with large stone slabs. Many of these houses had never been re-occupied; they were found whole and still "locked up", during excavations. for more details, please read Teleilat el Ghassul#Excavations) . == Subsistence ==
