Diatessaron

The Diatessaron is the most prominent early Gospel harmony that sought to combine all the textual material found in the four gospels—Matthew, Mark, Luke, and John—into a single coherent narrative of Jesus's life and death. Tatian's harmony follows the gospels closely in terms of text but, in order to fit all the canonical material in, he created his own narrative sequence, which is different from both the synoptic sequence and John's sequence; and occasionally creates intervening time periods that are found in none of the source accounts.

This sequence is coherent and consistent within itself, but not necessarily consistent with that in all or any of the separate canonical gospels; and Tatian apparently applies the same principle in respect of the narrative itself. Where the gospels differ from one another in respect of the details of an event or teaching; the Diatessaron resolves such apparent contradictions by selecting one or another alternative wording and adding consistent details from the other gospels; while omitting apparent duplicate matter, especially across the synoptics.

Year: 170-175 AD
