In the first part Cronagrafi,a, Eusebius expounds the chronological systems of the Chaldeans, Assyrians, Hebrews, Egyptians and Greeks. In the second, he presents a series of synchronous tables Cronikoi. kano,nej in parallel columns, giving the most important events of universal history, including those of sacred history, with references to different computi years from Abraham, whose birth was fixed at 2016 2015 BC; Olympiads; years of Rome, dynastic dates. Berlin Map His work was distinguished from its predecessors by the good quality of his chosen sources, a more marked philological and historical sensibility he no longer began with Adam but with historically ascertainable persons and events and a more prudent eschatological vision abandoning millenarism.
Less than a century later, while staying in Constantinople in ca. 380, Jerome discovered it, understood its importance and translated it into Latin, partially rewriting and expanding it: indeed, after translating the first part he introduced many new facts into the later parts, especially relating to the West, for which his work was intended; he also brought the Chronicon up to date as far as 378, the date of Valens’s death.
Thus there developed in early Christian literature, both Eastern and Western, the historical narrative in which events were registered simply in order of succession: a minor literary genre, but one which constituted the necessary skeleton for more complex historical narrative. Not by chance did Eusebius, on the basis of his own Chronicon, construct his Historia ecclesiastica for the centuries after Christ’s coming.
Later times thus found basic models to which they could look when compiling universal chronicles and indispensable points of reference for the broad delineation of humankind’s past e.g., the Chronicles of Sulpicius Severus, Prosper of Aquitaine, Hydatius, Marcellinus Comes, and again Cassiodorus, Victor of Tunnuna, Marius of Avenches, Isidore of Seville and Bede, for the West; and for the East, the universal chronicles of Panodorus and Annianus, Hesychius of Miletus and John of Antioch, or of John Malalas or George Syncellus.
