The Monastery of the Cave was established by Sabas in 508 CE as recounted by Cyril of Scythopolis (V. Sab. 37, 126; V. Iohannis 9, 208). As opposed to many other monasteries in the Judean Desert, the monastery continued to function well into the Early Islamic period. Probably due to the decline in the number of monks, leadership of Spelaion was joined with that of the Monastery of Castellion, located nearby and a common abbot served the two monasteries. During this period, the monastery was also known as the "Cave of St. George" (V. Stephani Sabaitae IX.1, 352 [ed. Garitte]).
