 All the complete manuscripts are liturgical in nature.Many of the palimpsests come from Saint Catherine's Monastery in Sinai (e.g., the Codex Climaci Rescriptus, Codex Sinaiticus Rescriptus), the Cairo Genizah and the Umayyad Mosque in Damascus and often transmit rare texts lost in the Greek transmission (e.g.a Dormition of the Mother of God, the hitherto unknown martyrdom of Patriklos of Caesarea, and the missing quire of Codex Climaci Rescriptus), or offer valuable readings for the text critique of the Septuagint.
