Whats missing from this graph is a big marker indicating "Collapse of the Roman Empire". Also the gradient should be significantly flatter in Rome's epoch than in Greece's.

Christianity has some blame to take, but it's not the whole story. Is it cause or effect? Plus this is Eurocentric and fails to address, say, Chinese science. And on the scale of the galaxy, let alone the universe, a thousand lost years probably isn't that big a deal. These days the entirety of civilised human history seems to me like the blink of an eye; what's interesting is how fast it all actually is, not that it it occasionally crashed.

It's not that I really disagree in principle but I'm not really sure that things could have gone any other way. Arguably that should be a previous valley just before the Egyptian section, which itself should go back to about 3000.
