the roman empire

which lived through the middle ages

kept pretty much everything in tact

monostaries

kept lots o things

and the more prosperous cities in italy and france did well in that regard as well

The point of being lost is, it doesn't exist
so you can't know what it was exactly that was lost

but thats also history youre postulating

and not some real technology

in which physical objects still exist

Technology was invented, lost and reinvented in many instances

but 40k and battletech postulate universes where even simple reverse engineering is impossible

its silly really

that is well documented

We lost orange carrots

They had to be remade

people claim things are lost when they really arent

Roman Concrete

constantinople remained unsullied from its inception to 1204

with all sorts of things there, knowledge of ancient technologies of course

they didnt reporudce things because they didnt need to

Just reverse engineer the concrete lmao

this is pure autism, guys

God, I love this server

Another one, the Egyptian writings Solon talks about

they were considered unnecessary to the needs of the current society

Then there's also greek computers that were lost

We get a small glimpse from what Solon passed on, but much of it is lost

lostech irl

holy shit that's awesome

Also roman steam power

If anything is evidence of time travel it's greece & rome

rome didnt have steam power

they had a spinny thing they found entertaining

It was proposed to use it for power

But the idea was dropped because slaves were currency

someone in the middle ages invented refrigeration too

they just used it for party tricks

So reducing their value would have basically ruined the post-money roman economy

Capitalism is what drives innovation
