Tatian
Overview
Tatian of Adiabene,[1] or Tatian the Syrian[2][3][4] or Tatian the Assyrian,[5][6][7][8] (/ˈteɪʃən, -iən/; Latin: Tatianus; Ancient Greek: Τατιανός; Classical Syriac: ܛܛܝܢܘܣ; c. 112 – c. 180 AD) was an Assyrian 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.[9] He was controversial in his own age due to his Gnostic influences, leading Russell to state Tatian "lived in the border between orthodox and Gnostic theology"
