This is a guest post by John Hessler, a specialist in the Library’s Geography and Map Division, focusing on computational geography and geographic information science. He’s also the Library’s curator of the Jay I. Kislak Collection. Recently, the Library’s Geography and Map Division acquired a rare 18th-century carving of a Theravãda Buddhist cosmography that originated in Myanmar (formerly known as Burma). The panel, which is more than 9 feet high when its three parts are fully assembled, shows the many levels that are the temporary resting places for living beings as they make their way to the ultimate goal of nirvana. The carving shows the levels that spiritual entities — humans, animals or gods – transmigrate. It pictures these way stations as floating palaces. It gives their names, the geography of the cosmos and the life of beings who temporarily reside in each of them.
