What is "tatian"

Tatian the Assyrian (; Latin: Tatianus; Greek: Τατιανός; Syriac: ܛܸܛܝܢܐ; c. 120 – c. 180 AD) was an Assyrian early Christian writer and theologian of the 2nd century.

Tatian's most influential work is the Diatessaron, a Biblical paraphrase, or "harmony", of the four gospels that became the standard text of the four gospels in the Syriac-speaking churches until the 5th-century, after which it gave way to the four separate gospels in the Peshitta version.
