The atlas · meta-layer
Every essay, in space and time
A cross-essay meta-layer: the whole corpus of maps plotted on one interactive map, and every essay charted on one shared timeline (ancient centuries compressed).
Alongside the corpus you can draw reconstructed territories, routes, frontiers, places and historical networks. Every layer answers the timeline, and every layer carries notes explaining its sources, how it was interpreted and how much of it was reconstructed. Those notes live in the Atlas Handbook.

The stato da màr as Venice ran it: harbours, the convoy lines between them, and the ground the Republic actually held.
A league drawn as what it was - cities, corridors and institutional events - and never as a territory it never had.
The Dacia programme on one map: where sources name places, what the province looked like, and how the frontier moved between 1829 and 1947.
The empire at its greatest reach and one province in detail - the same Roman Dacia layers, read as Roman rather than as Dacian.
A continent that was drawn before it was seen, and the tracks, sightings and removals that slowly replaced the drawing with a coastline.
A drawn road that is not a map, a sea campaign whose intention, diversion, claim and possession were four different things, and the city all of it was pointed at.

Cross-essay radar
Compare arguments, then inspect their vocabularies
The six shared scores are editorial discovery aids normalized from 0–1. They make a visual comparison possible; they do not make different essays, sources, or native concepts naturally commensurable.
One timeline, every essay
Note: the scale is deliberately non-linear - a critical atlas measures time the way its maps measured space, with its own compressions and silences.
