Metallurgy would need to be way much more advanced compared to what they had for effective firearms or cannons. Rockets on the other hand would be possible though relatively ineffective, and bombs would help against fortifications during sieges.

>Metallurgy would need to be way much more advanced compared to what they had for effective firearms or cannons

this was my concern. could they make the advancements needed just by being exposed to the knowledge of them?

i assume you are also gonna innovate centuries of metalworking to make decent boilers, right?
And dismantle slavedom, to make it a more economically efficient alternatives than putting a bunch of captives to work.
Muh roman steam revolution is the biggest meme ive ever seen.

>innovate centuries of metalworking to make decent boilers

what the flying fuck does this mean? what takes centuries? trial, error and learning what works? if you already know, what takes centuries? what technological hurdles are there?

Given that Romans had easy access to sulfur, charcoal, and saltpeter you could easily get them gunpowder.

>Metallurgy

A simple blast furnace using the Open Hearth Process was well within Rome's technological ability. Just this process alone would be transformative, suddenly all your iron can be steel cheaply and easily.

Or just skip that and give them smokeless powder instead. en.wikipedia.org/wiki/Poudre_B

Why would they believe me tho?
How would I convince them I'm right

I'd draw up a map of the world and hope the Aztecs and Maya can fight off the Romans enough to keep their culture alive and create cultural exchange

Prove yourself by giving them something shiny like gunpowder. Also the scientific method would be something the Romans really loved, it's the ultimate technology, one that continuously refines and improves other technologies.

How developed was the culture of the Americas at this time? Do you think if the Romans had an expedition there would they make it?
And would the natives learn about metal?

Well they did work copper and obviously gold and silver. I think some northwest coast tribes might have had even bronze. Roman contact might have revolutionized their society and might not (remember Vinland). And there's always the chance of shit like smallpox spreading and basically killing off all those societies.

Yeah but Aztecs had a more advanced society with buildings and cities
I mean would they have like cool Aztec metal armor and swords
Is it possible that they could have invented ships if they saw them?

I would bring steroids and turn Legionaries into superhuman beefcakes who will wrestle Hannibal's elephants like little children.

Aztecs rose to any sort of relevance in 1300s hundreds when mongols still ruled China and Timur ravaged lands from Central Asia. If you add antiquity Roman contact something like Aztecs wouldn't even happen in all likelihood.

Damn what if the Mongols went east with boats instead of west

Mongols couldn't even get over the Sea of Japan to glorious Nippon so I wouldn't count on it.

Simply making large satchel charges would be a game changer. Get a bunch of troops to pile them up against an enemy wall or in sapping tunnels and enjoy being able to crush any single defensive fortification in the world.

Set up an army general staff and make a bureaucracy leaps and bounds more advanced than anything the world will see for centuries.
