World Maps!

 

Ptolemy's world map

 World map by 6th century traveler and writer, Cosmas Indicopleustes. Depicts a flat world that is very difficult to read. The fellow, an Alexandrian Greek, traveled to Axum in Ethiopia as well as southern India.

Ibn Hawqal's 10th century world map, south on top.

Kashgari Map, from the 11th century. Map oriented to east on top.

Al-Idrisi's map of the world for the king of Sicily, Roger II from the 12th century. The map depicts the Nile and Niger as connected rivers,  since it was a widely held belief among Islamic geographers that the two rivers were one and the same. Notice how it depicts the two sources of the Nile, one in the highlands of Ethiopia and the White Nile's deep in East Africa. Besides not representing sub-equatorial Africa very well, this map is a surprisingly accurate depiction of the "Old World." Southeast Asia, the Indian subcontinent, and East Asia is definitely lacking in detail, as well as southern Africa.

Hereford Map, medieval Germany. Dated back to ca. 1285.

Psalter Map depicting the world from 13th century Christian European perspective. East is at the top of the map.

Pietro Vesconte's world map, oriented to the east at the top. 14th century.

Portion of the Catalan Atlas, 14th century, depicting Europe, Mediterranean and northern Africa

Da Ming Hun Yi Tu, from 15th century China, depicting the world centered on China and East Asia. The earliest known world map from East Asia, it depicts Europe and Africa very poorly. By this era, after centuries of contact with Islamic geographers and traders, as well as Chinese navigators and trade in the Indian Ocean and Southeast Asia, the cartographer had a general idea of Europe and Africa. Africa is depicted with a gigantic lake in the interior, probably due to hearing about the Great Lakes of East Africa from contact with Islamic and East Africans.

Kangnido map from the early 15th century, Korea. Depicts Europe and Africa quite poorly, with the same mega-lake in the interior of Africa that we see in the Da Ming Hun Yi Tu map. Of course, it's centered on China and East Asia, so there are obvious problems there. Check out the labeled portion of western Afro-Eurasia here:

De Virga world map from early 15th century. Seems to semi-accurately depict the continent of Africa, at least getting parts of the western, southern, and eastern coasts several decades before the Portuguese reached the Cape of Good Hope.

Fra Mauro world map from 1457 with a South-North orientation. Fra Mauro knew about the coasts of southern Africa, referring to the Cape of Good Hope as "Cape Diab" and used many Indian and Arabic names for portions of the southern and eastern coasts of Africa. It's quite fascinating to see such an accurate depiction of a portion of the African continent that was indeed connected with the much broader Atlantic and Indian ocean worlds and cultural contact zones than previously thought. Indeed, Swahili, Shona, and other peoples interacted with and traded with Arabs and Persians on the East African coast as far south as Mozambique during the Middle Age. And it's perfectly plausible that Zheng He's expeditions crossed over into the western coast of the African continent in the early 15th century. 

Cantino Planisphere from early 16th century depicts the Americas, Africa, and Eurasia.

Ruysch Map of 1507

Pietro Coppo map from 1520

Jean Rotz's world map made in the mid-16th century

Columbus map depicting known world before crossing the Atlantic. As you can see, West Africa figures prominently here and there are two West Africans visible.

 Based on Mateo Ricci's mappa mundi made in China in the early 17th century

In summation, I suppose my reasoning for including this list of extensive world maps is to illustrate that peoples living in different areas of the "Old World" knew about each other and had sufficient seafaring and traveling to document it through these amazing maps. Africa, for instance, was never the "Dark Continent" because so many Islamic, Asian, and even European geographers had a great idea of the continent's varied topography, waterways, and interior. Indeed, ancient Islamic maps suggest a keener understanding than one would expect of the Nile's sources in East Africa. Ignoring the obvious error of a Nile-Niger rivers combined, and the heavily flawed Islamic maps drawing on Ptolemaic worldviews, these earlier maps are not too horribly inaccurate.
