The ancient 'Gospel of the Mixed' merged four stories into one

In short: In the 2nd century, a Christian scholar named Tatian took the four separate Gospels and fused them into a single, coherent narrative. This 'Gospel of the Mixed' became the standard scripture for Syrian Christians for centuries, creating a unique literary hybrid that prioritized narrative flow over independent accounts.

Created between c. 166–169 AD (or about ad 150), the Diatessaron was an ambitious project by Tatian, an Assyrian apologist. His goal was to combine the material of Matthew, Mark, Luke, and John into a single life of Jesus. Unlike later harmonists who tried to prove the four gospels were consistent, Tatian sought to create a unified narrative. To achieve this, he rearranged the sequence of events, occasionally creating intervening time periods not found in any single source, and resolving contradictions by selecting one wording while weaving in details from the others.

The work was remarkably efficient: it was about 72 percent the length of the four gospels combined, as Tatian removed roughly a quarter of the text deemed redundant. For example, in the healing of the blind at Jericho, he reported only one man (Bartimeaus) instead of the three distinct accounts found in the synoptics. Archaeologists unearthed a Greek papyrus piece from Doura-Europus during 1933, though the primary Syriac or Greek versions remain missing. The text survived primarily through 4th-century commentaries and later translations into Arabic, Persian, and various European languages.

The Diatessaron's influence was vast. It served as the standard lectionary in some Syrian churches from the late 2nd to the 5th century. In the Latin West, it circulated as a supplement to the four gospels. Its legacy persists in vernacular harmonies; for instance, an 11th-century Arabic harmony preserves Tatian's exact sequence, while a 13th-century Persian version follows a different arrangement. Its history is also marked by controversy, as the bishop Theodoret reportedly destroyed copies in 423 AD, suspecting Tatian of heresy.
