The backstory is interesting. The map first showed up in the 1950s, bound into a book that was owned by a Spanish-Italian dealer, Enzo Ferrajoli. He did not explain where it had come from, but that wasn't uncommon in the years after the chaos of WWII. Ferrajoli sold the book and map for $3,500 to a US dealer, Laurence Witten, who also further obscured its origins[0]. Later, a benefactor purchased it on behalf of Yale, for $300,000 Notably, when Yale announced their discovery of the map, in 1965. The original source, Ferrajoli, was already in prison in Spain, charged with stealing other manuscripts (which he had also sold to Yale the year before)[1] edit: added a citation [0] https://www.maphistory.info/saenger.html https://www.maphistory.info/saenger.html para. 13- [1] https://www.nytimes.com/1964/11/07/archives/dealer-defends-rare-yale-mss-says-they-were-not-stolen-but-sold-by.html https://www.nytimes.com/1964/11/07/archives/dealer-defends-r...
