Roman Full Plate Armor?

[SigniferOne]

So what do these medieval 'inventions' have to do with full-plate armor? Are you telling me that the Romans were somehow inherently unable to equip their soldiers in it if they so decided to?

Even in Renaissance Europe only the most wealthy could afford a complete harness made of custom-tailored articulated plate. I doubt the Romans could have outfitted anyone but the elite in such armour (assuming they had the capacity to make it).

I guess that's my question ultimately: do you think they had the capacity to make it? Does the crupellarius suit (and the Dendra one) show that it was possible, or are there key technological leaps that would still remain absent?
