Mappa Mundi

Approximately 1100 mappae mundi (maps of the world) have survived from the Middle Ages; about 200 are separate maps; the rest are in books.

Maps of the world were obviously limited by knowledge of geography. This did not deter medieval cartographers, however, since maps existed for along time not as guides for travelers, but as diagrams of the layout of God's creation. Minutiae weren't as important as portraying the overall plan, or showing a particular feature. For instance, Gervase of Canterbury's Mappa Mundi was drawn up specifically to show the bishopric s and ecllesiastical foundations of England, Scotland and Wales.

One of the most common of the map designs was the T-O design, called that by modern scholars because it resembled those letters. The "T" was the division of the major landmasses with the enormous Asia topping Europe and Africa; "O" was the encircling Ocean.

Note that Asia is on top. When choosing proper positioning for the arrangements of the continents, the direction of the rising sun seemed to be a logical place to begin. East is therefore placed at the top of the maps, and the arrangement of things in their proper place on a map therefore was called "orienting."*

Cicero's Dream of Scipio (in which a vision of the world is viewed in detail) was very popular in the Middle Ages for what it had to say about the world and the divine. Macrobius' (5th century CE) Commentary on it was how many readers became familiar with it. Many copies of the Commentary include mappa mundi of the type therefore called Macrobian. The Dream includes a description of the various zones, cold to temperate to hot to temperate to cold. Only the temperate zones were considered habitable.

Fourteen manuscripts of Beatus of Liébana's (c.730-800) popular Commentary on the Apocalypse of St. John include the quadripartite-style map that squeezes the Antipodes into the extreme south.

The most famous and most detailed maps provide the most variety and data and start to approach the realism and usefulness of modern cartography. The symbolic value of the mappae mundi began to be replaced by the need for accurate information to aid in travel and, especially, navigation on the seas. The new "Portolan Charts" became far more valuable to have and reproduce, and the number of mappa mundi were produced less.

If you would like to see some maps from across the ages, a good start is the Imaginary Museum.

*An extra tidbit: "orient" comes to Middle English from Latin via French and the verb oriri, "to rise"; once in English it starts being used for the direction itself in which the sun rises.

The Antipodes

As the unknown becomes close and familiar, imagination must seek new realms further away. Modern fiction doesn't write about alien life on the Moon or Mars or Venus, since we now "know" those spheres. In the Middle Ages, it was assumed that fantastical lands and creatures existed "over there." As far lands such as Africa, for instance, began to be explored and found mundane, the fantastical was mentally placed in a more distant spot.

The Antipodes (literally "opposite feet": the place on the globe directly opposite to where you are standing)* fascinated the Middle Ages for both philosophical and geographical reasons. On the one hand, the idea had come to them from the Classical World, and so was difficult to dismiss. This was the place that held creatures out of legend: Cyclopes, dog-headed men, Sciopods whose single large foot could be used as an umbrella when they lay on their backs, Blemmyae with faces on their torsos. On the other hand, the Medieval idea of symmetry demanded that there be lands to the far south, balancing the known lands in the north. Especially as the idea of earth's roundness took shape, Africa wasn't enough to satisfactorily balance Europe and Asia.

The Antipodes were also a natural extension of the theory of "zones." Since it became very cold up north, and hotter as you went south, it was assumed that the temperate zone enjoyed by most of Europe had a counterpart below the equator which was equally inhabitable. Below that, of course would be the area that is opposite the Arctic: the Anti-Arctic, or Antarctic.

The term was first used by Plato in his Timaeus. It was first used in English in 1398 in John of Trevisa's translation of Bartholomaeus Anglicus' De Proprietatibus Rerum (On the Order of Things):
Yonde in Ethiopia ben the Antipodes, men that haue theyr fete ayenst our fete.
(Yonder in Ethiopia are the Antipodes, men that have their fete against our feet.)
Some in the Middle Ages used the image of upside-down men as a reason to reject the Earth as a globe and opt for a flat Earth. Plato had addressed this himself, however, in an assumption of orientation that he does not call gravity but that works the same way:
For if there were any solid body in equipoise at the centre of the universe, there would be nothing to draw it to this extreme rather than to that, for they are all perfectly similar; and if a person were to go round the world in a circle, he would often, when standing at the antipodes of his former position, speak of the same point as above and below; for, as I was saying just now, to speak of the whole which is in the form of a globe as having one part above and another below is not like a sensible man.
But sensible men apparently did not read the Timaeus, or never grasped the concept of "up" and "down" being relative to where you were standing. A universally accepted map of the world was unknown; maps of the world typically took one of four forms, which we will look at tomorrow.

*Have fun finding your antipodal point here.
