Chronology first allows us to place the various chapters within Daniel’s life journey.
The book begins under Nebuchadnezzar and continues down to the Persian period. The order of the chapters is not, however, strictly chronological: the visions of Daniel 7 and Daniel 8 belong to the reign of Belshazzar and therefore precede the fall of Babylon recounted in Daniel 5.
This observation shows that the organization of the book answers to a literary and theological logic as much as to a historical one.
The hypothesis adopted in this study, according to which Daniel would have been about fourteen years old at the time of his deportation in 605 BC, also allows us to follow his aging approximately. It is not a datum explicitly provided by the text, but a chronological marker used to better perceive the extent of his journey.
Daniel thus appears as a man whose life spans several decades and several political regimes.
