The Earliest Life of Christ Ever Compiled from the Four Gospels: The Diatessaron of Tatian

In the second century, well before the canonical gospels took their present form, Tatian wove from the four gospels and one or more Judaic-Christian gospels one harmonized account of the life of Christ, the Diatessaron. The Earliest Life of Christ is an English translation of the Diatessaron based on the Arabic version, itself a translation from the lost Syriac.
