‘The importance of the Orthodox rite of St Catherine’s Monastery at the foot of the 2,300-metre Mount Sinai (Jebel Musa, also known as Horeb) in the Sinai Peninsula grew only after the loss of Jerusalem in 1187 and the fall of the Latin states in the Holy Land in 1291…It is the oldest monastery in the world to have survived in this way, where, among other things, the oldest 4th-century Greek-language manuscript of the Bible, the Codex Siniaticus, has also been preserved.’
