Does Menzies plan to explain why renaissance art and literary forms bear
no resemblance whatsoever to Chinese models if they - not the classical world -
were the inspiration?

Mind you it isn't exactly impossible that Chinese envoys should have visited
15th c. Italy. But they would almost certainly have come overland by way of the
Silk Road and I can't see them having much cultural impact but rather being treated
as exotic curiousities.
