Mount Sinai, granitic peak of the south-central Sinai Peninsula, Janūb Sīnāʾ (South Sinai) muḥāfaẓah (governorate), Egypt. Mount Sinai is renowned as the principal site of divine revelation in Jewish history, where God is purported to have appeared to Moses and given him the Ten Commandments (Exodus 20; Deuteronomy 5). According to Jewish tradition, not only the decalogue but also the entire corpus of biblical text and interpretation was revealed to Moses on Sinai. The mountain is also sacred in both the Christian and Islamic traditions. Because scholars differ as to the route of the Israelite exodus from Egypt and the place-names in the scriptural account cannot be identified in terms of present sites, a positive identification of the biblical Mount Sinai cannot be made. Mount Sinai itself, however, has long been accepted as the site in the traditions of Judaism, Christianity, and Islam.
In the early Christian era the area was frequented by hermits, and in 530 ce the monastery of St. Catherine was built at the northern foot of the mountain. Still inhabited by a few monks of the autonomous Orthodox Church of Mount Sinai, it is probably the world’s oldest continuously inhabited Christian monastery (see Saint Catherine’s). Its library of ancient biblical manuscripts, including the famous 4th-century Greek Codex Sinaiticus (now in the British Museum), has been invaluable in reconstructing the text of the Bible.
The mountain, which rises to 7,497 feet (2,285 metres) above sea level, was under Israeli administration from the Six-Day War of 1967 until 1979, when it was returned to Egypt. It has become an important pilgrim and tourist site.
