Tatian
Tatian the Assyrian (c. 120–180) 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, when it gave way to the four separate gospels in the Peshitta version.
