The most significant difference between al-Idrisi’s Tabula Rogeriana and our modern Google Earth map, is, of course, its orientation: the Tabula Rogeriana is oriented south-up, and we in modern times are most accustomed to thinking of north as upwards. This difference reflects a variation in religious and cultural beliefs. Muslims, such as Muhammad al-Idrisi, the map’s creator, and Ibn Battutah, a well-traveled medieval jurist, would think of south as being downwards and closer to hell, because in Islamic cosmology hell was cold. On the other hand, our modern satellite maps, made in a culture dominated by those of European descent, continue to place the European continent at the top of the world. And because this culture is also largely dominated by Christianity, we might tend to think of the hotter southern lands as being more hellwards. Ibn Battutah might have thought of his journey as being relatively safe (at least, as safe as travel could be in that era), because he remained mostly in warmer, more “heavenly” zones, and didn’t journey terribly far into the hellishly cold northern climates. The Tabula Rogeriana also places Mecca as the center of the world, which is something Ibn Battutah likely would have internalized as well. A modern satellite map, however, has no center, and one can scroll across the whole map in one seamless loop.
The Tabula Rogeriana contains only the world that was known at the time, and focuses mainly on Europe, West Asia, and North Africa. It is most detailed around the Mediterranean, and becomes less detailed the further east it goes. Eastern cities such as Delhi, which Ibn Battutah visited during his travels, are nowhere to be found on the map. So embarking on such a journey could feel dangerous, as one is quite literally stepping into the unknown. Travel during modern times, on the other hand, is far easier to navigate, since satellite maps are able to provide an accurate image of an area, down to specific buildings and landmarks. Traveling is far less stressful and pathways are less unknown, because if one is lost, one can simply open the satellite map and use their location to pinpoint exactly where they are in relation to everything around them. Modern maps also allow us to view the entire world, because we are able to literally send a camera up into space and take pictures of everything, and so we have knowledge of entire continents and landmasses that were completely unbeknownst to the people of Ibn Battutah’s time.
The Tabula Rogeriana is surprisingly accurate for a map made long before the era of satellite photography. To draw the shapes of the landmasses so faithfully, especially over such a large area, is an impressive feat indeed. That being said, the map is the most accurate along the coastlines of the Mediterranean. It would, after all, be far easier to draw a city located on the coast than to draw one further inland, where there may not be as significant a geographical feature to locate it by. While mapping Ibn Battutah’s journey on the Tabula Rogeriana, I had a far easier time locating the coastal cities he visited. With the inland ones, though, I sort of had to take my best guess and zoom in, and then scan around a lot until I found a phonetically similar name (as I cannot read Arabic, I used a version of the map that had been helpfully transliterated into the Latin alphabet). For travelers such as Ibn Battutah, moving away from the coastline may have felt more like entering uncertain territory, since it’s easier to get lost and disoriented without an idea of what landmarks you can reference along your way. The Tabula Rogeriana also does not make any real distinction between cities based on size or landmarks, although there are a few exceptions. Alexandria is drawn with its iconic lighthouse, and there’s a grouping of four cities further east surrounded by a circular, almost spiky looking wall. Beyond that, though, there’s very little to differentiate one city from the next. Natural features such as mountains or rivers abound, but if one were to become completely lost and stumble upon some mountain or river, it would be very difficult to identify exactly which one you were looking at by using the map. Or, worse, you could follow a river or navigate around a mountain believing it to be the landmark needed to stay on your route, only to discover they were two completely different mountains and you’ve gone the wrong way entirely. Your best hope in order to ensure you take the right path and get to your destination would be to rely on locals familiar with the area. Much different than travel in this day and age, when any idiot can pull up Waze to tell them which route to take.
