Room 2 of 7
The Map
Cartography, projection, and navigation - the craft and argument of the map itself.
This is the room where the map turns to look at itself. Projection, scale, symbol, and survey are not neutral techniques but arguments - each a claim about which distortions are worth accepting so that others can disappear. The Map asks: what does every gain in accuracy, usability, or control quietly cost somewhere else? Read against the grain, eight thousand years of world-mapping become a ledger of such sacrifices - the sphere flattened, the coastline generalised, the unknown filled with confident ornament. Here the craft is inseparable from its politics: to measure is already to decide what counts as worth measuring. We treat the map not as a window onto the world but as a made thing, with a maker, a method, and a motive - and we ask what each of those leaves in shadow.

The Cartographic Sacrifice
A Non-Linear History of Mapping
Eight thousand years of world-mapping read against the grain: every leap in accuracy, usability, or control exacts a quiet sacrifice in some other way of understanding space.

Atlas layers
- Depicted extents (corpus) The area each corpus map depicts - one footprint polygon per map, keyed by mapId.
- Dacia name attestations (reviewed) Where a source does or does not name a place in the Dacia corpus. This layer carries only records cleared by human review, and is empty until that review happens.
- Dacia name attestations (research tier, unreviewed) The full CND 1.0 release candidate: every compiled attestation including silences and normalized imports, none of it cleared by human review. Records here may not be cited as established evidence.
- Roman Dacia · principal sites Legionary fortresses, road stations and mining centres of the province. Every point is the corpus's own reference location for that place, carrying the corpus's provenance: none is an excavated centroid.
- Roman Dacia · roads and frontier corridors The province drawn as a network: roads are lines through attested stations, and the limes are corridors this project drew. Nothing here is digitised from a survey, and the dashes say which is which.
- Principalities and provinces, 1526-1859 Wallachia, Moldavia and Transylvania as dated phases rather than as one timeless outline, so that Habsburg Oltenia, Bukovina and Russian Bessarabia appear when they existed and not before. The rings are editorial envelopes, not delimitations.
- Josephinian survey · sheet index Where the First Military Survey of Transylvania, 1769-1773, covers the corpus. Each footprint links to the repository that holds the sheet; no scan is served from here, and the footprints are reconstructed rather than taken from the archive index.
- Treaty frontiers, 1829-1947 What each settlement moved, as dated phases. Not one instrument in the source ledger has delimitation geometry this project can use, so every line is drawn and declared editorial; where two sources give different lines for one moment, both are kept rather than averaged into a frontier nobody proposed.
- Terra Australis, the conjectured south (unreviewed) The region within which early modern maps drew a southern continent, as a schematic envelope rather than a coastline. No map in the register has been examined, so there is nothing to digitise, and drawing a plausible outline would manufacture the confidence this layer exists to question.
- Antarctic observations and fixes (unreviewed) Dated positions from Cook to the loss of Endurance: farthest souths, the contested sightings of 1820 and 1840, the nineteenth-century landfalls and the Endurance sequence. A sighting is filed as a report rather than an observation wherever what was seen is still argued over.
