took control of Masada, and from there they launched raids against communities in the Dead Sea region. The Roman Legio X Fretensis rose on Masada in eight camps, and constructed a large siege ramp. Josephus claimed that the siege ended in a mass suicide, when the 960 Sicarii rebels present decided to kill themselves rather than be sold into slavery. Jewish refugees, primarily army commanders, officials, and their families, escaped to hideout caves during the final stages of the Bar Kokhba revolt, especially after the fall of Betar in 135 CE. Many of these caves were discovered in the Judaean Desert's deep ravines, near intermittent streams. These include the caves in Nahal Michmas, the Almisiya cave, the Murabba'at caves in Nahal Darga, the pool cave in Nahal David, the Cave of Horror and the Cave of Letters (where the letters Simon bar Kokhba wrote to the residents of En Gedi and the Babatha archive were discovered) in Nahal Hever, and three caves in Tze'elim Stream. Early Christian monasticism The Judaean Desert is connected with early forms of Christian monasticism. There are examples of Desert Fathers and Desert Mothers and a number of other influential Christian figures, some of which spent much of their lives in the desert as hermits or as members of monastic communities of the lavra or the cenobium type, or on the fringe of the desert in or near settled places such as Bethlehem and Jerusalem, but are still considered to belong to the same monastic environment. A short chronological list can include Chariton the Confessor (mid-3rd century – c. 350), Hilarion the Great (291–371), Euthymius the Great (377–473) and his associate Theoctistus of Palestine (died 451 or 467), Jerome (c. 342/47–420) with his associates Paula of Rome (347–404) and her daughter Eustochium (c. 368–419/20) as well as Tyrannius Rufinus (344/45–411), Melania the Elder (ca. 350–417?) and her granddaughter Melania the Younger (c. 383–439), Mary of Egypt (c. 344–421), Gerasimus of the Jordan (5th century), Theodosius the Cenobiarch (c. 423–529) and his contemporary Sabbas the Sanctified (439–532), at whose monastery John of Damascus (c. 675/76–749?) spent much of his life. Cyriacus the Anchorite (448-557) knew Euthymius and Gerasimus and led for many years the Souka of Hilarion. Cyril of Scythopolis (c. 525–559) wrote about the desert monasticism of his time, as did John Moschus (c. 550–619). Archeology The Judaean Desert has been the site of many archeological
