W:Gavin Menzies wrote a book 1421 claiming Zheng He's fleets sailed much further, to at least California, Argentina & Australia, and that Columbus used Chinese maps obtained via trade with Egypt. I've read it & found much of it plausible, though most historians dismiss it.
Is that worth a mention? Probably not, but it seems worth asking. Pashley (talk) 02:19, 16 May 2020 (UTC)
I assume it's based on the 2006 map. I'd say yes, with a note citing the historians who disagree. SelfieCity 10:46, 16 May 2020 (UTC)
How much does the article need to get into historian controversies? We're not an encyclopedia, but a travel guide. Ground Zero (talk) 11:56, 16 May 2020 (UTC)
