How is al-Idrisi’s map different from Ptolemy’s map of the world? Does al-Idrisi know more or less about Africa than Ptolemy did? Why did al-Idrisi choose to center his map on the Arabian Peninsula? How is this map different from a modern map? Why do you think this might be?
Put away all these pictures, and try to draw your own map of the world, using only what you already know about the shape of the continents. Where will you center your map? Which direction will be up? How good is your map compared to these early maps?
