🔍 Om kildene og historisk datering
Å tidfeste hendelser tusenvis av år tilbake i tid er en krevende historievitenskapelig oppgave. Før innføringen av den julianske kalenderen (45 f.Kr.) og den gregorianske kalenderen (1582) benyttet ulike sivilisasjoner (romere, grekere, kinesere, babylonere) vidt forskjellige kalendersystemer basert på månesykluser eller lokale embetsperioder.
Slik merker vi dateringene:
• ✓ Sikker datering: Dokumentert i samtidige protokoller, offisielle traktater eller etter standardiserte kalendersystemer.
• ⚠️ Usikker / estimert: Hendelsen er historisk reell, men datoen er tradisjonell, basert på senere krøniker eller lunisolare omregninger.
