Czech historians working in the research library in the city of Olomouc stumbled across a copy of a 1563 nautical atlas — only the sixth known to exist — by the Catalan cartographer Jaume Olives, Radio Praha reports. The story of how it arrived in Olomouc is a story in itself, and somewhat of a mystery — it’s a rather landlocked country, after all — but they believe it arrived some time after 1784. The library plans to digitize the rare atlas and make it available online, presumably here. Via Map the Universe.
