The first literary work in the Caucasian Albanian alphabet was discovered on a palimpsest in Saint Catherine's Monastery on Mount Sinai in 2003 by Dr. Zaza Aleksidze; it is a fragmentary lectionary dating to the late 4th or early 5th century AD, containing verses from 2 Corinthians 11, with a Georgian Patericon written over it. Jost Gippert, professor of Comparative Linguistics at the University of Frankfurt am Main, and other have published this palimpsest that contains also liturgical readings taken from the Gospel of John.
