Abstract

That the famous Syrus Sinaiticus contains not only the Old Syriac Gospels, but also other palimpsest leaves, among them four leaves of a Greek codex of John’s Gospel, is not a secret. Nevertheless, for 120 years, this Greek fragment, though probably contemporary with the great uncials, was not registered in any list of nt manuscripts and, as a result, completely neglected. The main aim of these pages is to recall its existence and to gather the information that is available at present.
