Maps & hidden lands
Buache knew subglacial Antarctic divisions
Cartographic interpretationEvidence status
Unsupported identification
Its speculative geography does not demonstrate knowledge of subglacial terrain.
Editorial assessment of this proposition; not a numeric confidence score.
Claim or proposition being examined
Buache’s map reveals Antarctic land divisions beneath modern ice.
Limitations
Documentation establishes historical circulation of the claim, not its truth; see counterevidence and source roles.
Scope of catalog verification
Source existence and described claim checked via web search/excerpts; not independent validation of alleged event.
Material cited and its limits
Buache southern lands map, 1739 catalog record — Keep this map distinct from 1754 states and modern subglacial interpretations.
Research context
BedMachine Antarctica version 3 is a scientific bed-elevation model. It is not a direct image of an ancient ice-free coastline or evidence of a lost civilization.

Connected records
These are contextual links, not automatic corroboration.
- The world beneath the ice.
Modern bed-elevation models offer comparison material; they do not demonstrate that an early cartographer had equivalent measurements.
- Buache’s map of the southern lands
The 1754 southern chart provides a concrete original for comparison. Keep its date and state distinct from other Buache maps and modern bedrock models.
- Oronce Fine records preglacial Antarctica
Compare the logic used to identify southern land across different maps, dates and editions.
