Through World map, Common Era and Middle Ages

With the Age of Discovery, during the 15th to 18th centuries, world maps became increasingly accurate; exploration of Antarctica, Australia, and the interior of Africa by Western mapmakers was left to the 19th and early 20th century.

Antiquity

Bronze Age Saint-Bélec slab

The Saint-Bélec slab discovered in 1900 by Paul du Châtellier, in Finistère, France, is dated to between 1900 BCE and 1640 BCE. A recent analysis, published in the Bulletin of the French Prehistoric Society, has shown that the slab is a three-dimensional representation of the River Odet valley in Finistère, France. This would make the Saint-Bélec slab the oldest known map of a territory in the world. According to the authors, the map probably was not used for navigation, but rather to show the political power and territorial extent of a local ruler's domain of the early Bronze Age.

Babylonian Imago Mundi (c. 6th c. BCE)

A Babylonian world map, known as the Imago Mundi, is commonly dated to the 6th century BCE. The map as reconstructed by Eckhard Unger shows Babylon on the Euphrates, surrounded by a circular landmass including Assyria, Urartu (Armenia) and several cities, in turn surrounded by a "bitter river" (Oceanus), with eight outlying regions (nagu) arranged around it in the shape of triangles, so as to form a star. The accompanying text mentions a distance of seven beru between the outlying regions. The descriptions of five of them have survived:

  • The third region is where "the winged bird ends not his flight", i.e., cannot reach.
  • On the fourth region "the light is brighter than that of sunset or stars": it lay in the northwest, and after sunset in summer was practically in semi-obscurity.
  • The fifth region, due north, lay in complete darkness, a land "where one sees nothing", and "the sun is not visible".
  • The sixth region, "where a horned bull dwells and attacks the newcomer".
  • The seventh region lay in the east and is "where the morning dawns".

Anaximander (c. 610–546 BCE)

Anaximander (died c. 546 BCE) is credited with having created one of the first maps of the world, which was circular in form and showed the known lands of the world grouped around the Aegean Sea at the center. This was all surrounded by the ocean.

Hecataeus of Miletus (c. 550–476 BCE)

Hecataeus of Miletus is credited with a work entitled Periodos Ges ("Travels round the Earth" or "World Survey"), in two books each organized in the manner of a periplus, a point-to-point coastal survey. One, on Europe, is essentially a periplus of the Mediterranean, describing each region in turn, reaching as far north as Scythia. The other book, on Asia, is arranged similarly to the Periplus of the Erythraean Sea of which a version of the 1st century CE survives. Hecataeus described the countries and inhabitants of the known world, the account of Egypt being particularly comprehensive; the descriptive matter was accompanied by a map, based upon Anaximander's map of the Earth, which he corrected and enlarged. The work only survives in some 374 fragments, by far the majority being quoted in the geographical lexicon the Ethnica, compiled by Stephanus of Byzantium.

Eratosthenes (276–194 BCE)

Eratosthenes (276–194 BCE) drew an improved world map, incorporating information from the campaigns of Alexander the Great and his successors. Asia became wider, reflecting the new understanding of the actual size of the continent. Eratosthenes was also the first geographer to incorporate parallels and meridians within his cartographic depictions, attesting to his understanding of the spherical nature of the Earth.

Posidonius (c. 135–51 BCE)

Posidonius (or Poseidonius) of Apameia (c. 135–51 BCE) was a Greek Stoic philosopher who traveled throughout the Roman world and beyond and was a celebrated polymath throughout the Greco-Roman world, like Aristotle and Eratosthenes. His work "about the ocean and the adjacent areas" was a general geographical discussion, showing how all the forces had an effect on each other and applied also to human life. He measured the Earth's circumference by reference to the position of the star Canopus. His measure of 240,000 stadia translates to 24,000 miles (39,000 km), close to the actual circumference of 24,901 miles (40,074 km). He was informed in his approach by Eratosthenes, who a century earlier used the elevation of the Sun at different latitudes and arrived at a result of roughly 250,000 stadia. Both men's figures for the Earth's circumference were uncannily accurate, aided in each case by mutually compensating errors in measurement. However, the version of Posidonius' calculation popularised by Strabo was revised by correcting the distance between Rhodes and Alexandria to 3,750 stadia, resulting in a circumference of 180,000 stadia, or 18,000 miles (29,000 km). Ptolemy discussed and favored this revised figure of Posidonius over Eratosthenes in his Geographia, and during the Middle Ages scholars divided into two camps regarding the circumference of the Earth, one side identifying with Eratosthenes' 250,000 stadion measure and the other with Posidonius' 180,000, which is now known to be about 33% too low. This was the number used by Christopher Columbus to underestimate the distance to India as 70,000 stades.

Strabo (c. 64 BCE – 24 CE)

Strabo is mostly famous for his 17-volume work Geographica, which presented a descriptive history of people and places from different regions of the world known to his era. The Geographica first appeared in Western Europe in Rome as a Latin translation issued around 1469. Although Strabo referenced the antique Greek astronomers Eratosthenes and Hipparchus and acknowledged their astronomical and mathematical efforts towards geography, he claimed that a descriptive approach was more practical. Geographica provides a valuable source of information on the ancient world, especially when this information is corroborated by other sources. Within the books of Geographica is a map of Europe. Whole world maps according to Strabo are reconstructions from his written text.

Pomponius Mela (c. 43 CE)

Pomponius is unique among ancient geographers in that, after dividing the Earth into five zones, of which only two were habitable, he asserts the existence of antichthones, people inhabiting the southern temperate zone inaccessible to the folk of the northern temperate regions due to the unbearable heat of the intervening torrid belt. On the divisions and boundaries of Europe, Asia and Africa, he repeats Eratosthenes; like all classical geographers from Alexander the Great (except Ptolemy) he regards the Caspian Sea as an inlet of the Northern Ocean, corresponding to the Persian (Persian Gulf) and Arabian (Red Sea) gulfs on the south.

Marinus of Tyre (c. 120 CE)

Marinus of Tyre's world maps were the first in the Roman Empire to show China. Around 120 CE, Marinus wrote that the habitable world was bounded on the west by the Fortunate Islands. The text of his geographical treatise however is lost. He also invented the equirectangular projection, which is still used in map creation today. A few of Marinus' opinions are reported by Ptolemy. Marinus was of the opinion that the Okeanos was separated into an eastern and a western part by the continents (Europe, Asia and Africa). He thought that the inhabited world stretched in latitude from Thule (Shetland) to Agisymba (Tropic of Capricorn) and in longitude from the Isles of the Blessed to Shera (China). Marinus also coined the term Antarctic, referring to the opposite of the Arctic Circle. His chief legacy is that he first assigned to each place a proper latitude and longitude; he used a "Meridian of the Isles of the Blessed (Canary Islands or Cape Verde Islands)" as the zero meridian.

Ptolemy (c. 150)

Surviving texts of Ptolemy's Geography, first composed c. 150, note that he continued the use of Marinus's equirectangular projection for its regional maps while finding it inappropriate for maps of the entire known world. Instead, in Book VII of his work, he outlines three separate projections of increasing difficulty and fidelity. Ptolemy followed Marinus in underestimating the circumference of the world; combined with accurate absolute distances, this led him to also overestimate the length of the Mediterranean Sea in terms of degrees. His prime meridian at the Fortunate Isles was therefore around 10 actual degrees further west of Alexandria than intended, a mistake that was corrected by Al-Khwārizmī following the translation of Syriac editions of Ptolemy into Arabic in the 9th century. The oldest surviving manuscripts of the work date to Maximus Planudes's restoration of the text a little before 1300 at Chora Monastery in Constantinople (Istanbul); surviving manuscripts from this era seem to preserve separate recensions of the text which diverged as early as the 2nd or 4th century. A passage in some of the recensions credits an Agathodaemon with drafting a world map, but no maps seem to have survived to be used by Planude's monks. Instead, he commissioned new world maps calculated from Ptolemy's thousands of coordinates and drafted according to the text's 1st and 2nd projections, along with the equirectangular regional maps. A copy was translated into Latin by Jacobus Angelus at Florence around 1406 and soon supplemented with maps on the 1st projection. Maps using the 2nd projection were not made in Western Europe until Nicolaus Germanus's 1466 edition. Ptolemy's 3rd (and hardest) projection does not seem to have been used at all before new discoveries expanded the known world beyond the point where it provided a useful format.

Cicero's Dream of Scipio described the Earth as a globe of insignificant size in comparison to the remainder of the cosmos. Many medieval manuscripts of Macrobius' Commentary on the Dream of Scipio include maps of the Earth, including the antipodes, zonal maps showing the Ptolemaic climates derived from the concept of a spherical Earth and a diagram showing the Earth (labeled as globus terrae, the sphere of the Earth) at the center of the hierarchically ordered planetary spheres.

Tabula Peutingeriana (4th century)

The Tabula Peutingeriana (Peutinger table) is an itinerarium showing the cursus publicus, the road network in the Roman Empire. It is a 13th-century copy of an original map dating from the 4th century, covering Europe, parts of Asia (India) and North Africa. The map is named after Konrad Peutinger, a German 15th–16th century humanist and antiquarian. The map was discovered in a library in Worms by Conrad Celtes, who was unable to publish his find before his death, and bequeathed the map in 1508 to Peutinger. It is conserved at the Österreichische Nationalbibliothek, Hofburg, Vienna.
