Fascinating stuff…
Imagine how far along we would be architecturally and engineering wise, if the barbarians hadn’t destroyed all of the Roman knowledge during the dark ages.
And also, if the great library of Alexandria hadn’t burned.
The library was burned by order of the caliph, centuries after Julius Caesar. The myth that Caesar burned is a pernicious falsehood.
It just proves it only takes a few to ruin the barrel leading to why we can’t have nice things.
