Four main Syriac versions of the Greek gospels survive, and some copies of these versions were later revised against further Greek gospel manuscripts. Many of these Syriac gospel versions survive in early manuscripts. Together with early Syriac patristic texts, these Syriac gospel manuscripts provide important datable evidence for three of the main endings to the Gospel of Mark, and for their reception in the Syriac-using churches of Syria and Mesopotamia. This article seeks to provide an up-to-date overview and assessment of their evidence.
