Map of Europe and the Mediterranean Sea (1525 CE)

This map reveals its priorities immediately. The Mediterranean is drawn with confidence and care, while northern Europe appears far less certain, stretched and simplified at the edges of Ottoman knowledge. That contrast is what makes the work so revealing. It shows not only what Piri Reis knew, but also which parts of the world mattered most to the sailors, merchants, and imperial planners for whom the Kitâb-ı Bahriye was made.

A Map from the 1525 Kitâb-ı Bahriye

The “Map of Europe and the Mediterranean Sea” belongs to the second edition of Piri Reis’ Kitâb-ı Bahriye, completed in 1525. In assembling it, Piri Reis drew on a combination of older European and Islamic cartographic traditions as well as his own maritime experience. The result is especially strong in its treatment of the Mediterranean, whose coastlines had been charted in great detail over centuries of navigation and trade. By contrast, regions farther north, including Scandinavia and Great Britain, appear with far less precision. That imbalance is not accidental. It reflects a world seen from the perspective of an Ottoman admiral for whom the Mediterranean was the central theater of movement, commerce, and power.

Knowledge at the Edges of the Known World

One of the most telling aspects of the map is the way it registers the unevenness of early 16th-century geographic knowledge. Piri Reis is thought to have relied much more heavily on secondhand reports and inherited maps for places such as England and Scandinavia, which lay beyond the main sphere of his own experience and outside the principal routes of Ottoman maritime concern. The map therefore preserves not only information, but also uncertainty. Northern Europe is included, yet it is not known with the same depth as the Mediterranean basin. In that sense, the distortions are historically valuable, because they show where firsthand navigational knowledge gave way to compilation and approximation.

A Mediterranean View of Europe

The differing levels of accuracy across the map reveal a great deal about Ottoman cartographic priorities. The Mediterranean, with its dense network of ports, islands, and coastal settlements, was a zone of intense political and commercial importance, and it is rendered accordingly. Northern Europe, by contrast, appears more as a geographical extension than as a region mapped for direct navigational use. This difference helps explain why the map feels so assured in the south and more tentative in the north. It is less a neutral image of Europe than a Mediterranean-centered view of the wider world.

Ink, Pigment, and Coastal Emphasis

The map is drawn on paper, with pages generally measuring about 22 × 32 cm (8.7 × 12.6 in.), and this example spans a double page. Piri Reis used ink and pigments to distinguish and clarify major features, with coastlines typically outlined in red and orange. In the Mediterranean sections, ports, islands, and coastal cities are shown with notable detail and confidence. Farther north, the outlines become rougher and less exact, especially in England and southern Scandinavia, where the shapes diverge more noticeably from actual geography. The contrast in treatment between these regions is one of the map’s most striking characteristics.

Preservation and Manuscript Survival

Maps from Piri Reis’ Kitâb-ı Bahriye survive today in several manuscript copies, the most famous of which are held in the Topkapı Palace Museum in Istanbul. Other copies are preserved in libraries and museums elsewhere in the world. These surviving examples are later manuscript copies rather than the original sheets made by Piri Reis himself, which have not survived.
