Where did it come from?
Begin with a specific artifact, text, observation, or question. Keep its origin visible.
Research, in the open
A compelling question starts the work. Sources, chronology, alternative explanations, and revision turn it into an investigation readers can follow.
Four useful questions
Begin with a specific artifact, text, observation, or question. Keep its origin visible.
Place the material in time and geography. Distinguish a date from an interpretation.
Compare alternative explanations and seek the evidence that could disprove a claim.
Show the current review state and make room for corrections when new sources arrive.
Ways to explore
Our introductory atlas groups historical subjects by broad periods. The evidence guide explains the kinds of sources a reader may encounter. These are orientation tools, not proof that two places were connected or that every relationship has been validated.

Start with a source guide and follow the sources and uncertainty it records.
