The medieval term mappa mundi (also forma mundi, historia/istoire) covers a broad array of maps of the world of which roughly 1100 survive. These have resisted systematic classification, but the clearly dominant type is one that aims at comprehensively symbolistic representation. Its early, schematic form is a disc composed of three continents surrounded and separated from one another by water (“T-O Map”) and associated with the three sons of Noah: Asia (Shem) occupies all of the upper half, Europe (Japhet) to the left and Africa (Ham) to the right share the lower half. Quadripartite cartographic schemes included the antipodes as a fourth continent, but the tripartite model was adopted by the large majority of the more developed world maps in use from the 11th century on and—with important variations—well into the Renaissance. While details were added as available space permitted, the Mediterranean continued to serve as the vertical axis and, with diminishing clarity, the rivers Don and Nile as the horizontal one. The map also continues to be ‘oriented’ towards Asia, where paradise sits at the very top. A circular ocean forms the perimeter and not infrequently the city of Jerusalem constitutes its centre....

Spolia in medieval art and architecture
Dale Kinney
In its most general sense, spolia (pl., from Lat. spolium: ‘plunder’) denotes all artifacts re-employed in secondary contexts, from building blocks reused in a wall to pagan gems mounted on a Christian reliquary. It is a matter of debate whether this broad application of the term is justified, or whether it should be restricted to the relatively small subset of reused objects that were taken or ‘stripped’ (like spoils) from their original context, rather than found, purchased, inherited or otherwise acquired by non-violent means. It is likewise debated when the use of spolia should be considered meaningful, if at all. Arnold Esch defined five possible motives for using spolia: convenience, profanation, Christianization, political legitimation and aesthetic attraction. Michael Greenhalgh has argued for reducing the motives to three (at least with regard to marble): pragmatism, aesthetics and ideology; while Finbarr Barry Flood cautioned against reductive interpretations generated by any taxonomy, insisting that reused objects are mutable in meaning and capable of multiple interpretations during their life cycle....
