Sources

Everything on this site rests on these. The ancient witnesses, what each one is worth, and how this site weighs them against each other.

Tier 1: Caesar himself

Tier 2: contemporaries

Tier 3: the biographers (1–2 centuries later)

Tier 4: later and fragmentary

How this site weighs them

  1. Contemporary beats later; hostile and friendly sources are triangulated, not averaged.
  2. Agreement across independent sources = the solid core. Single-source anecdotes are labeled as such.
  3. Numbers in ancient sources (casualties, sums, crowds) are treated as order-of-magnitude at best.
  4. Omens, dreams, and deathbed speeches are literary conventions until corroborated.
