Interesting claims

Proof of ancient advanced seafarers

Charles Hapgood's 1966 bestseller argued the map copies lost source maps showing Antarctica's coast as it looks under the ice, implying a prehistoric seafaring civilization with advanced cartography. The theory remains a staple of ancient-mystery media.

Assessment: Cartographers identify the mystery coastline as South America drawn with a rotated orientation and copied errors. No ice-free Antarctica needed.
Documented

What the admiral actually said

Piri Reis wrote his sources on the map itself: about twenty charts, including Portuguese maps and one belonging to Columbus. His notes describe compiling them. The map is a documented product of the Age of Discovery's information explosion.

Assessment: The map tells us its own origin, in its own margins. Few fringe theories have a smoking gun this convenient to check.
Stories

The library that burned but kept talking

The story the map's fans tell: Piri Reis copied from far older charts, survivors of Alexandria's library, possibly from a seafaring civilization whose maps showed coasts nobody had yet charted. The admiral himself wrote that he used about twenty old maps, including one from Columbus.

Assessment: The admiral's own note is documented and is the only solid piece. Everything beyond it, the library, the lost civilization, is the story filling in what the note does not say.

Worth asking

If one genuine artifact can generate sixty years of theories, what does an artifact actually prove: the past, or our hunger for a different past?
