The Diatessaron is the most prominent Gospel harmony created by Tatian, an early Christian apologist and ascetic.The term "diatessaron" is from Middle English by way of Latin, diatessar n, and ultimately Greek, . Tatian combined the four gospels Matthew, Mark, Luke, and John into a single narrative.Tatian's harmony follows the gospels closely in terms of text but puts the text in a new, different sequence. The four gospels are different from each other, and combining them into one story is tantamount to creating a new story different from each original.Like other harmonies, the Diatessaron resolves conflicting statements. For example, it omits the conflicting genealogies in Matthew and Luke. In order to fit all the canonical material in, Tatian created his own narrative sequence, which is different from both the synoptic sequence and John's sequence. Tatian omitted duplicated text, especially among the synoptics. The harmony does not include Jesus' encounter with the adulteress, a passage that some consider not to be original to John.
