Methodology

The rules this site runs on. Read this to know exactly what a certainty label means, what counts as a quotation, and where the line is drawn.

Certainty labels

Every timeline date and many claims carry one of five labels:

Label Meaning
certain Dated by multiple converging sources (e.g. the Ides of March).
attested Reported by an ancient source with no reason to doubt it.
probable Reconstructed from good evidence (e.g. the Rubicon crossing’s approximate date).
disputed Scholars or sources disagree (e.g. the birth year).
traditional The conventional date/claim; evidence thin but long-standing.

Absence of a label means the claim is presented as the scholarly consensus; contested points always get one.

Quotation policy

Source weighing

Contemporary sources outrank later ones; independent agreement outranks single testimony; archaeology outranks anecdote. Ancient numbers (casualties, sums, crowds) are treated as order-of-magnitude. Omens and deathbed speeches are literary conventions until corroborated. Full policy: Sources.

What is never invented

No invented dates, quotations, statistics, consensus claims, or “typical day” scenes presented as fact. Dramatized material (the stream scripts, character art) is fenced off and labeled as dramatization. Where evidence runs out, the site says “we don’t know” — see the “What we don’t know” boxes throughout.

The birth-date problem (worked example)

Caesar’s birthday shows the system in action. The tradition gives 12 July 100 BC. But:
