They can be found in the Apology to Autolycus (Apologia ad Autolycum) by Theophilus (AD 115-181), the sixth bishop of Antioch, His chronology begins with the biblical first man Adam through to emperor Marcus Aurelius, in whose reign Theophilus lived.
The chronology puts the creation of the world at about 5529 BC: "All the years from the creation of the world amount to a total of 5,698 years." Dr.
In the section Sanctification of the Moon (11.16), he wrote of his choice of Epoch, from which calculations of all dates should be made, as "the third day of Nisan in this present year ...
which is the year 4938 of the creation of the world" (March 22, AD 1178).
The later Latin translation called the Vulgate, an interpretative translation from the later Masoretic Text (a Jewish revision and consolidation of earlier Hebrew texts), replaced it in the west after its completion by St. 405, Latin being the most common vernacular language in those regions.
The earliest extant Christian writings on the age of the world according to the biblical chronology were therefore based on the Septuagint, due to its early availability.
Ben Zion Wacholder points out that the writings of the Church Fathers on this subject are of vital significance (even though he disagrees with their chronological system based on the authenticity of the Septuagint, as compared to that of the Hebrew text), in that through the Christian chronographers a window to the earlier Hellenistic biblical chronographers An immense intellectual effort was expended during the Hellenistic period by both Jews and pagans to date creation, the flood, exodus, building of the Temple...
In the course of their studies, men such as Tatian of Antioch (flourished in 180), Clement of Alexandria (died before 215), Hippolytus of Rome (died in 235), Sextus Julius Africanus of Jerusalem (died after 240), Eusebius of Caesarea in Palestine (260-340), and Pseudo-Justin frequently quoted their predecessors, the Graeco-Jewish biblical chronographers of the Hellenistic period, thereby allowing discernment of more distant scholarship.
Jews in these regions used Seleucid Era dating (also known as the "Anno Graecorum (AG)" or the "Era of Contracts") as the primary method for calculating the calendar year. Jacob then put this question: How do we know that our Era [of Documents] is connected with the Kingdom of Greece at all?
Why not say that it is reckoned from the Exodus from Egypt, omitting the first thousand years and giving the years of the next thousand? Said Rav Nahman: In the Diaspora the Greek Era alone is used.
The Alexandrian Era of 25 March 5493 BC was adopted by church fathers such as Maximus the Confessor and Theophanes the Confessor, as well as chroniclers such as George Syncellus.
Its striking mysticism made it popular in Byzantium especially in monastic circles.
While differences in biblical interpretation or in calculation methodology can produce some differences in the creation date, most results fall relatively close to one of these two dominant models.
