| Summary | Some claim that the 1513 Piri Reis map shows Antarctica without ice, implying ancient knowledge of the continent before it froze. This is used as evidence for an advanced ancient civilization. |
| Origin | The Piri Reis map was drawn in 1513 by Ottoman admiral Piri Reis. Claims about its Antarctic depiction gained popularity in the 20th century. |

| Evidence / consensus | The map's southern landmass is likely a hypothetical continent based on the belief in a southern landmass. Ice core data show Antarctica has been ice-covered for millions of years, and the map's depiction does not match the actual coastline. |
