Ghassulian refers to a culture and an archaeological stage dating to the Middle and Late Chalcolithic Period in the Southern Levant (c. 4400–c. 3500 BC). Its type-site, Teleilat Ghassul (Teleilat el-Ghassul, Tulaylat al-Ghassul), is located in the eastern Jordan Valley near the northern edge of the Dead Sea, in modern Jordan. It was excavated in 1929-1938 and in 1959-1960, by the Jesuits. Basil Hennessy dug at the site in 1967 and in 1975-1977, and Stephen Bourke in 1994-1999.
The Ghassulian stage was characterized by small hamlet settlements of mixed farming peoples, who had immigrated from the north and settled in the southern Levant - today's Jordan, Israel and Palestine. People of the Beersheba Culture (a Ghassulian subculture) lived in underground dwellings - a unique phenomenon in the archaeological history of the region - or in houses that were trapezoid-shaped and built of mud-brick. Those were often built partially underground (on top of collapsed underground dwellings) and were covered with remarkable polychrome wall paintings. Their pottery was highly elaborate, including footed bowls and horn-shaped drinking goblets, indicating the cultivation of wine. Several samples display the use of sculptural decoration or of a reserved slip (a clay and water coating partially wiped away while still wet). The Ghassulians were a Chalcolithic culture as they used stone tools but also smelted copper. Funerary customs show evidence that they buried their dead in stone dolmens and also practiced Secondary burial .
