There are conflicting interpretations of the map. Scholarly debate exists over the specific sources used in the map's creation and the number of source maps. Many areas on the map have not been conclusively identified with real or
mythical places. Some authors have noted visual similarities to parts of the Americas not officially discovered by 1513, but there is no textual or historical evidence that the map represents land south of present-day
Cananéia. A disproven 20th-century hypothesis identified the southern landmass with an ice-free Antarctic coast.

[.] In the top left corner, the Caribbean is arranged unlike modern or contemporary maps. The large island oriented vertically is labeled Hispaniola, and the western coast includes elements of Cuba and Central America. Inscriptions on South America and the Southern Continent cite recent Portuguese voyages.

Many places on the map have been identified as
phantom islands or have not been identified conclusively. ''İle Verde'' (Green Island) north of Hispaniola could refer to many islands. The large island in the Atlantic, ''İzle de Vaka'' (Ox island), corresponds to no known real or fictional island.

Analysis

Compared to the Islamic cartography of the era, the map shows an atypical knowledge of foreign discoveries. During the
Age of Discovery
The Age of Discovery (), also known as the Age of Exploration, was part of the early modern period and overlapped with the Age of Sail. It was a period from approximately the 15th to the 17th century, during which Seamanship, seafarers fro ...
, European voyages expanded the known world and disrupted the traditional conception of an "inhabited quarter" of the world comparable to the Greek
ecumene. The attitudes towards the Age of Discovery within the Ottoman Empire ranged from passive indifference to the outright rejection of foreign influence.
Piri Reis synthesizes traditional worldviews with discoveries by undermining their newness, using rhetorical strategies to reframe European discoveries as the rediscovery of ancient knowledge. He invokes
Dhu al-Qarnayn—believed to be a
reference to Alexander the Great from the Quran—in his inscriptions regarding Columbus.
According to the
Quran
The Quran, also Romanization, romanized Qur'an or Koran, is the central religious text of Islam, believed by Muslims to be a Waḥy, revelation directly from God in Islam, God (''Allah, Allāh''). It is organized in 114 chapters (, ) which ...
and Turkish literary tradition, Alexander traveled to every corner of the world, thereby defining its limits. A marginal inscription describes world maps as "charts drawn in the days of Alexander".
Another inscription mentions that a "book fell into the hands" of Columbus describing lands "at the end of the Western Sea". In the 1526 version of Piri Reis' atlas, the ''Kitab-ı Bahriye'', he explicitly credits European discoveries to lost works created during legendary voyages of Alexander.
Compared to earlier portolan charts, the map shows gradual improvement.
Portuguese source maps would have been similar to surviving maps like the 1502
Cantino Planisphere. Compared to the planisphere and the earlier
map of Juan de la Cosa (1500): the Atlantic Ocean is accurate, South America is highly detailed, and the Caribbean is strangely organized. As a part of the expanding cartography of the sixteenth century, the map was soon surpassed.
[.] Piri Reis's own 1528 map included a more detailed and accurate version of the
New World

. Despite recent claims of an anomalous level of accuracy, Gregory McIntosh, in comparing it to several other
portolan-style maps of the era, found that:
The Piri Reis map is not the most accurate map of the sixteenth century, as has been claimed, there being many, many world maps produced in the remaining eighty-seven years of that century that far surpass it in accuracy.

began a project of creating copies of traditional Islamic maps in the
Book of Roads and Kingdoms tradition. Piri Reis adapted the elements of iconography from the
traditional maps—which illustrated well-known routes, cities, and peoples—to the portolan portrayals of newly discovered coasts.
Piri Reis provides an unusual etymology of "Ocean" as coming from "''Ovo Sano''", or "sound egg". The accepted etymology comes from the world-encircling river,

. Historian Svat Soucek has described the egg etymology as naive. Historian Karen Pinto has proposed that the egg etymology is better understood in the context of traditional attitudes towards the deep seas in Islamic culture. Typical medieval world maps followed a standardized and schematic design, with a disc-shaped "inhabited quarter" of the world separated from
Mount Qaf by an impassable Encircling Ocean. Pinto observed that Piri Reis had reconciled the discovery of new land beyond the sea with this existing model, by framing the

Caribbean

The Caribbean islands and the coastline in the Northwest corner of the map are widely believed to be based on a lost map drawn by Christopher Columbus, or under his supervision. The western coast on the map combines features of Central America and Cuba, reflecting Columbus's claim that Cuba was part of an Asian mainland. During the 1494 exploration of Cuba, Columbus was so adamant that he had found Asia, that he had a notary board each of his ships anchored off the coast. Columbus compelled his men to swear that Cuba was a part of Asia and agree to never contradict this interpretation "under a penalty of 10,000 maravedis and the cutting out of the tongue". The mainland in the extreme northwest is labeled with place-names from Columbus's voyages along the coasts of Cuba. For example, a stretch of coast is labelled ''Ornofay'', as recorded by Columbus but depicted on no other maps.
Peculiar features of the Caribbean can be attributed to Columbus. Notably, a massive

Antilia, and
Cipangu (Marco Polo's Japan) between Europe and Asia. The general position and shape of Hispaniola are similar to contemporary maps of Cipangu.
The absence of the island's distinctive
Gulf of Gonâve is more evidence of a Columbian origin because he did not explore Hispaniola's western shore. According to Gregory McIntosh, the most clearly matching coastlines are around Cabo Falso in
Pedernales. The island near Cabo Falso is labelled with a Turkish translation of
Alto Velo Island, explored and named by Columbus on his
second voyage in August 1494. The peninsulas protruding from Puerto Rico are not present in reality but are also depicted on the
map of Juan de la Cosa, who sailed with Columbus. ''İle Bele'' near Puerto Rico is possibly
Vieques, named ''Gratiosa'', or Graceful, by Columbus.
There is disagreement on how much of the map draws from Columbus. Kahle and most later scholars attributed everything north and west of the phantom island Antilia to this source. Soucek expressed doubts about Kahle's claim, which included some of the South American coast.
McIntosh found that Cuba, Central America, The Bahamas, and Hispaniola could be clearly attributed to an early map from Columbus,

Svat Soucek noted that the parchment curves by South America, and that "it was not unusual for cartographers to adjust the orientation of a coastline to fit the surface available".

Captain Arlington H. Mallery, a civil engineer and amateur archaeologist who was a supporter of
pre-Columbian trans-oceanic contact hypotheses. Mallery used a grid system to reposition the coordinates on the map and claimed the accuracy of these reconstructed maps to be comparable to modern maps. Mallery's ideas were exposed to a wider audience when Georgetown University broadcast a discussion between Mallery, director of the Weston Observatory Daniel Lineham, and director of the Georgetown University Observatory Francis Heyden in 1956. Inspired by Mallery, historian
Charles Hapgood, in his 1966 book ''Maps of the Ancient Sea Kings'', proposed a theory of global exploration by a pre-classical undiscovered civilization based on his analysis of

and late-medieval maps. Hapgood's book was met with skepticism due to its lack of evidence and reliance on
polar shift. Hapgood acknowledged that his theory disregarded the text and some of the placement of land masses on the map. For example, he designated an island to be one-half of Cuba—claiming it was "wrongly labeled ''Espaniola''" or Hispaniola—and remarked that, "nothing could better illustrate how ignorant Piri Re'is was of his own map."
Hapgood, and his graduate students who aided with the research, were influential in spreading the idea that the Piri Reis map shows Antarctica as it looked during the

, where land rises after massive ice sheets melt away. Additionally, the 1949 survey could not measure even one percent of the area drawn in the Piri Reis map. Subsequent studies with access to more data have shown no significant similarities to Antarctica's coast beneath the ice or a projected Antarctic coastline without ice.
Hapgood mistakenly believed that Antarctica had been free of ice in 17,000 BC and partially ice-free as late as 4,000 BC. This erroneous date range could have put the mapping of Antarctica contemporary with many known prehistoric societies. More recent ice core data shows that Antarctica was last free of ice over ten million years ago. Writers like
