An old Burmese map of the world, showing elements of medieval map-making techniques, according to the 1906 text, The Thirty Seven Nats. A Phase of Sprit-Worship prevailing in Burma, by the wonderfully named Sir Richard Carnac Temple.
In many ways, this text feels like something of an almost Lovecraftian tome. For those creating literature or games set in an alternate history or secret history setting, I think this certainly gives a great reminder that the European powers weren't always the center of everyone else's concepts of the world. Consider how we might present it to our audiences.
