The Syriac Sinaiticus or Codex Sinaiticus Syriacus (syrs), known also as the Sinaitic Palimpsest, of Saint Catherine's Monastery, or Old Syriac Gospels is a late-4th- or early-5th-century manuscript of 179 folios, containing a nearly complete translation of the four canonical Gospels of the New Testament into Syriac, which have been overwritten by a vita (biography) of female saints and martyrs with a date corresponding to AD 697. This palimpsest is the oldest copy of the Gospels in Syriac, one of two surviving manuscripts that are conventionally dated to before the Peshitta, the standard Syriac translation.
