Begin with a dated map
An alternate Roman history needs more than colouring a large area on a map. Choose a date, identify the authority your map represents and explain the evidence behind its borders. Do not combine territories from different centuries into one supposedly historical empire.
The Metropolitan Museum’s Africa & Byzantium exhibition highlights connections involving North Africa, Egypt, Nubia, Ethiopia and the Byzantine world. It is a reminder that Mediterranean history cannot be explained through Europe alone, or by treating neighbouring societies as empty space waiting for expansion.
Make separate layers
Create three maps or overlays:
- Political claims: areas a government claimed or administered at your chosen date.
- Connections: documented movement of objects, people or ideas, with uncertainty indicated.
- Your alternative: the single change introduced by the scenario.
Give every historical layer a source. Use a different colour or line style for invention. A trade connection does not prove political rule, and a claim to territory does not necessarily demonstrate effective control.
Follow a journey
Choose a fictional traveller and a practical purpose. What route could they use? Where might they need permission, supplies or an interpreter? Research those details for the particular time and place rather than borrowing them from an undifferentiated Roman past.
Change one crossing or agreement and show how the journey changes. This keeps the counterfactual concrete without promising that a new border would produce an earlier industrial revolution.
Review your map
Ask another reader to identify what is known, inferred and invented. If they cannot tell, improve the legend. Leave gaps where the evidence is insufficient.
The finished map should make an argument that can be questioned. It should not imply that political fragmentation ended creativity or that imperial unity would inevitably have produced peace. For a companion exercise about objects moving across boundaries, explore the Byzantine dish at Sutton Hoo.

Reviewed on 26 September 2026. Removed the misleading Dark Ages narrative and automatic technological progress; differentiated the article with a sourced, clearly hypothetical mapping exercise.
