It also assumes that the period was sparked by an enormous flowering and outpouring of culture and technology etc. that seemingly came from nowhere, rather than merely a continuance of the trends which had been forming for the past several centuries.
Oh yeah, there's that too. But it has less of the unfortunate implications then the assumption that
obviously Muslims and Jews can't accomplish anything with the proper conditions for the Renaissance. Still absolutely awful from a historical perspective though.
I don't really like the term "Renaissance" because it implies that first there was nothing and then snap of the fingers and you have Leonardo and Donatello and Raphael and the de'Medici and Ghiberti, and Brunelleschi, etc, when this absolutely was not the case.
I don't like Renaissance because you can't even define what it means. If you mean an enormous flowering and outpouring of culture and technology, like you said, the Renaissance definitely didn't happen in Italy, which kind of pulls down the whole idea.
On the other hand, if you mean some sort of cultural movement, and artistic style, it's limited, and never fully takes hold, even in the best of circumstances. There's no clear geographic scope anymore (except, AFAIK it seems to always refer to somewhere in Christendom), because the term is tied to a particular narrative that's factual untrue.
But it's a popular idea about the past, so we try to invent new narratives to justify the term. It seems it's not as important what the Renaissance means, as long as it means something, so we can keep talking about it.
Yes, and the question is why the Europeans acted on those knowledge. And I guess the point of discussion is that you claimed it's because of their advanced metallurgy.
No, because that's still presupposing that this knowledge was a force that actually produced substantial change in Europe. My point is that it didn't. Europe had substantial economic and technological advantages by the 15th century, and continued to build on those advantages.
