Sir John Mandeville’s journey is significantly different visually when plotted on the Hereford Mappa Mundi rather than a modern map. Most obviously, because the Hereford Mappa Mundi is oriented with east on top of the world, Mandeville seems to be traveling up and to the right rather than down and to the right. The route plotted on the modern map seems impractical and even nonsensical, in large part due to Sir John Mandeville’s misunderstandings of geography. Once plotted on the Hereford Mappa Mundi, which contains even more geographical mistakes itself, the route which is supposed to be one of the best ways to Jerusalem seems even more ridiculous. Both maps have several places where Mandeville seems to double back on himself or make a small loop, but on the modern map the loop takes place in the coastal cities of Syria and Israel, most likely due to Mandeville’s misunderstanding of how the cities are ordered down the coastline. However, on the Hereford Mappa Mundi, not only does John Mandeville not know where some of the locations he claims to have visited are located, but the map’s author does not know either. Most obviously, the labyrinth on the map that represents the island of Crete (where John Mandeville describes visiting Rhodes) is drawn much too far south in the Mediterranean, nowhere near Greece or Turkey. The island of Cyprus is not labeled at all, so I chose a larger island close to where it would realistically be located based on the modern map and called is Cyprus. I did the same with the coastal towns and cities of Syria and Israel, labelling them along the coast as closely as possible to where they were located on the modern map. The Hereford Mappa Mundi also did not have Saint Albans or Nicaea on the map, so I set them in the middle of England and Turkey, hopefully close to where they might be located. Overall, however, the Hereford Mappa Mundi is surprisingly accurate for the time. Sir John Mandeville’s ridiculous route looks very similar on both the medieval and modern map.
