Using bows and arrows as an example when you've got wonders of pretty advanced engineering like the Parthenon, plus they also had ballistae, chariots and catapults, so not the peak at all.
Not only that, but even the bows were more advanced, composite bows much more powerful than simple ones made of wood.
I'll start: https://en.wikipedia.org/wiki/Aeolipile
... what other things / proceses / materials / frame of mind made the steam engine possible vs. this.
What made for an industrial revolution in the 1800's vs. the 1st century AD).-
In all seriousness, it's impressive what knowledge sharing and cooperation achieves.
They did not have internal combustion engines, or electricity, or the ability to machine parts to high tolerances, but ancient engineers cared deeply about efficiently transforming mechanical energy from one form to another.
