>make full body plate armor
ackshually
we pretty much stagnated technology-wise for ~1000 years
and we regressed in some respects
<this was issued to rank and file footsoldiers during the republic era
200 bce iirc.
i mention footsoldiers because full plate armor was issued to elite combattants only with everything it implies, in design and logistics, central power, technological process

architecture might be one of the rare instances where we saw an evolution
and even that is disputable because alot of roman techniques were lost throughout the ages
