This catalogue is a brief report of Arabic and Syriac manuscripts found at Saint Catherine's Monastery, compiled by Margaret Dunlop Gibson and her sister.

The work of the remarkable sisters Agnes Smith Lewis and Margaret Dunlop Gibson, this lectionary of what is now known as Christian Palestinian Aramaic, was re-edited in the light of two manuscripts from the Sinai, which they recovered, and from Paul de Lagarde’s Evangeliarium Hierosolymitanum. An important document for the textual criticism of the New Testament as well as for the early practice of the church, Lewis and Dunlap added to its value by composing this light “critical edition.” Presented in Syriac with English annotations to the Greek text of the Gospels, this useful study will be welcome by New Testament scholars and Syriac scholars alike.

The variety of Arabic versions of the New Testament is bewildering. In this work, Gibson provides one particular text of the Acts of the Apostles, as well as those of the Minor Catholic Epistles, based on an eighth or ninth century manuscript, preserved at the Convent of St. Catharine in Sinai. The volume also includes a treatise on the Triune nature of God, with an English translation.

A vibrant tale of two journeys to St. Catharine's Monastery in Mount Sinai that lead to the discovery of an ancient codex containing an old version of the Syriac Gospels.
