The map was made for Roger, king of Sicily. The red lines are trade routes. This is a reproduction kept in UAE’s Sharjah Museum.

I ran across the unglobed map before I found the planisphere at the online British Museum’s ‘Silk Road’ exhibition. Go there and look for the text ‘Map of the world from al-Idrisi’. https://www.artnews.com/art-news/news/british-museum-silk-roads-exhibition-1234722468/
I found the planisphere image on the Wikipedia page for ’ Tabula Rogeriana’, which shows several chunks of the map. (Idrisi maps all have ‘South’ on the top of the map.) In the ‘significance’ section, there’s a big version of the map. None of them are maps of the whole Earth … it’s said that his maps were all based on what people who’d been there told him.
