In 1996, Zaza Aleksidze of the Georgian Centre of Manuscripts discovered at Saint Catherine's Monastery at Mount Sinai, Egypt, a text written on parchment that had been reused in a Georgian palimpsest. In 2001 Aleksidze identified its script as Caucasian Albanian, and the text as an early lectionary dating to perhaps before the 6th century. Many of the letters discovered in it were not in the Albanian alphabet listed in the 15th-century Armenian manuscript.
