Tatian wrote his ~Euangelion dia tôn tessarôn~ as early as the year 170.
It is no longer extant, but we have some reason for believing that this
Harmony had been compiled in an unfriendly spirit (Theodoret, _Hæret.
Fabul._, lib. i. c. 20.). Tatian was followed by Ammonius, whose
~Harmonia~ appeared about 230; and in the next century by Eusebius and
St. Ambrose, the former entitling his production ô~Peri tês tôn
Euangeliôn diaphônias~, the latter _Concordia Evangelii Mattæi et Lucæ_.
But by far the ablest of the ancient writings on this subject is the _De
Consensu Evangelistarum_ of St. Augustine. Many authors, such as
Porphyry, in his ~Kata Christianôn logoi~, had pointed with an
air of triumph to the seeming discrepancies in the Evangelic records as
an argument subversive of their claim to paramount authority ("Hoc enim
solent quasi palmare suæ vanitatis objicere, quod ipsi Evangelistæ inter
seipsos dissentiant."--Lib. i. c. 7.). In writing these objections St.
Augustine had to handle nearly all the difficulties which offend the
microscopic critics of the present day. His work was urged afresh upon
the notice of the biblical scholar by Gerson, chancellor of the
University of Paris, who died in 1429. The _Monotessaron, seu unum ex
quatuor Evangeliis_ of that gifted writer will be found in Du Pin's
edition of his _Works_, iv. 83. sq. Some additional information
respecting Harmonies is supplied in Ebrard's _Wissenschaftliche Kritik
der evangelischen Geschichte_, pp. 36. sq. Francfurt a. M., 1842.
