Cyprianus Gallus or Cyprian the Gaul is the conventional name of the poet who wrote a Late Latin epic versification of the historical books of the Old Testament based on the Old Latin translation, although only his version of the Heptateuch (Heptateuchos) has survived to the present day. He has sometimes been credited with the authorship of two other poems, Carmen de Sodoma and Carmen de Iona, but neither fits his style and language. These have also been attributed to Cyprian of Carthage and Tertullian.
