5. Age (_aetas_) is used properly in two ways: for it is either the age of man, as infancy, prime, old age; or the age of the world, whose first age is from Adam to Noe; the second, from Noe to Abraham; the third, from Abraham to David; the fourth, from David to the migration of Judah to Babylon; the fifth, from then to the coming of the Saviour in the flesh; the sixth, which is now in progress and which will continue until the world is ended. 6. Julius Africanus was the first of our [writers] to set forth in the style of simple history, in the time of Marcus Aurelius Antoninus, the passing of these ages by generations and reigns. Then Eusebius, bishop of Caesarea, and the priest Hieronymus of holy memory, published a complex history of chronological tables, using reigns and dates at the same time.[307] [307] The reference in “complex history” (_complicem historiam_) is to the parallel sets of chronological tables of the histories of different peoples given by Eusebius. 7. Then others, among them especially Victor, bishop of the church of Tununa, reviewed the histories of earlier writers and filled out the deeds of subsequent ages down to the consulate of the second emperor Justinus. 8. We have noted with what brevity we could the total of these times from the beginning of the world to the emperor Augustus Heraclius and Suinthilanus, king of the Goths, adding at the side a column of dates by the evidence of which the total of past time may be known. Chapter 39. On the ordering of times (chronology).[308] [308] Sufficient of Isidore’s chronology is translated to give an idea of its method and of the events mentioned in it. His dates for the six ages of the world are as follows: First age 0–2242. Second age 2242–3184. Third age 3184–4125. Fourth age 4125–4610. Fifth age 4610–5155. Sixth age 5155-? The world according to Isidore’s chronology was in its 5825th year. Although Isidore professes to start the sixth age with the birth of Christ, he really starts it with the beginning of the reign of Augustus. See _Chronicon_; Migne, _P. L._, vol. 83, col. 1038. 1. The first age contains at its beginning the creation of the world. On the first day under the name of light God created the angels; on the second, under the name of firmament, the heavens; on the third, under the name of parting, the waters and the land; on the fourth day, the lights of heaven; on the fifth, living things of the waters; on the sixth, living things of the land and man, whom he called Adam. [Years] 2. Adam in his 230th year begat Seth, from whom [sprang] the children of God. 230 Seth in his 205th year begat Enos, who began to call upon the name of the Lord. 435 Enos in his 190th year begat Cainan. 625 Cainan in his 170th year begat Malaleel. 795 _Second Age_
