Red granite ramparts of Jebel Serbal thrust towards the heavens. Near here, at the oasis of Feiran, an important center of Christian monasticism was located during the Byzantine period. A bishop served at this center, overseeing the spiritual well-being of all the Sinai monks and hermits.
In the sixth century, a Sinai traveler named Cosmas Indicopleustes identifed a mountain near Feiran as Mt. Sinai; he was probably writing of Jebel Serbal, which sheltered several monasteries during the Byzantine period.
