… the largely unempirical and abstract nature of Greek natural philosophy and the fact that it was generally socially divorced from the practical arts of engineering and architecture meant that most Greek and Roman scientists did little to advance technology, and the idea that the Great Library would have been filled with men excitedly sketching flying machines or submarines is, once again, a fantasy. When all this is pointed out some New Atheists try to invoke counter-evidence. They often claim, for example, that Hero of Alexandria worked at the Great Library and that he invented the steam engine. Even a scientist who has not studied history past high school (i.e. most of them) will have dim memories of the history of the Industrial Revolution and would therefore know it had something to do with the invention of steam engines, so surely Hero brought the ancient world to the brink of industrial transformation. Well, actually, no.
Hero does seem to have been another exception to the rule when it comes to philosophers tinkering with gadgets and it’s possible (though far from certain) that he worked in the Mouseion. But the practical applications of his study of pneumatics and dynamics were more toys and curiosities than any great leaps forward in technology. He famously made an aeolipile, though he didn’t actually invent it, given that it had already been described by the Roman engineer and architect Vitruvius, but this can only be called a “steam engine” in the loosest sense of the term. Hero’s little device was not capable of doing anything more than spinning in place and Roman technology lacked the high tensile metallurgy, the mathematics or the precision tooling that would be required to make a true steam engine. The other technological wonder that is often invoked here is the Antikythera mechanism. Exactly how this intricate mechanical orrery based on a geocentric model is supposed to indicate some nascent Industrial or Scientific Revolution is never made clear, but not only did it have no connection to the Great Library, it was a kind of instrument known since the third century BC. If it is evidence that the Greco-Roman world was on the brink of a technological revolution and was only stymied by the rise of Christianity, one has to wonder what kept them from achieving this wondrous thing for the 600 years between its invention and the conversion of Constantine.
The New Atheist mythic conception of the “Great Library of Alexandria” bears very little resemblance to any historical actuality. It was a shrine with scholars attached to it, not a secular university. Its scholars were far more concerned with poetry, textual analysis, grammar, lexicography and rhetoric than anything we would see as “science”. The proto-science they did do was mainly of a highly abstract and often metaphysical nature rather than anything like modern science. And it was also generally divorced from technical innovation and what little practical application it was given did not much at all to advance technology. The idea that if the Great Library had not been burned down by wicked Christians we’d all be living in gleaming space cities on Europa or Callisto is, therefore, a silly fantasy. And not least because the Great Library … wasn’t burned down by wicked Christians.
