A systematic chronicle of the late Roman and Byzantine period that organizes events in strict chronological order and synthesizes information from Byzantine, Greek, Latin, legal and medieval sources alongside available oriental writings. The narrative compiles imperial affairs and interactions with neighboring Asian peoples, highlighting gaps, corrupted names and contradictions in the primary texts. The edition interleaves corrections, additions and explanatory notes drawn from Armenian, Syriac, Arabic and Persian materials where possible, and emphasizes source criticism and annotation to clarify, supplement and restore the historical record presented by earlier compilers.
