The Piri Reis Map and Esoteric Antarctic Claims

Record summary

The Piri Reis map is an Ottoman chart fragment whose depiction of parts of the Atlantic has attracted claims that it shows Antarctica before its modern discovery. Esoteric and alternative-history writers have used it as evidence for vanished civilizations or impossible ancient knowledge. Mainstream cartographic scholarship instead emphasizes compilation from earlier charts, distorted coastlines, and uncertain identification of depicted regions. The map matters for comparing historical artefacts with occult diffusion narratives, while its date, provenance, and source components remain subjects for specialist analysis.
