    I find it very a very romantic notion to have unknown areas on the world. Like some desert in the far south, beyond which might lie anything.

      We have that today with outer space. For all intents and purposes it is the new ocean, and so far we’ve only put a few skiffs in it.

        Yeah, but it’s a lot harder to cross. Like, I could build a shitty boat from wood myself. A spaceship? Not so much. Especially not if it’s actually supposed to leave this gravity well.

          It’ll eventually be more commonplace. Probably not build a raft level of simple, but eventually there will be common access.

            I doubt we’ll get that far before running out of resources (especially oil, which is necessary for pretty much everything even though not necessarily directly for space travel) and/or climate change ends mass-scale industrial society. Long term space travel is incredibly hard and it has a ton of effects on the human body, and solving those problems will be pretty low on our priority list when shit really hits the fan

              I’m a little more optimistic about it. It’s definitely insanely difficult to do, and I don’t think a lot of people even get how hard it is and the crazy out of this world (literally) hazards there are with just flying to the moon and Mars.

              But more than one country has sent things to the moon, and we seem to have low earth orbit cracked, so I can definitely see people normalizing moon transit and beyond in the inner solar system.

              It gets even more hazardous past that though. But like the oceans before I really do believe humanities strive for exploration will endure and someday we’ll go further and further.

              Extra-solar system is a giant flashing question mark though. That might be the next new ocean, and might take us just as long if longer, if even ever, to conquer.

                We could put people on Alpha Centauri in 88 years with 50s technology like Project Orion. The really hard part is figuring out a way to make us use the technology we do have for things like that, instead of for bombing each other back to the stone age.

              Regarding the problem of running out of oil, I look at it a bit like, “we are a plant (biological plant)”.

              The plant starts in a seed, which provides it with nutrients (energy) as some kind of starting bonus. It can use these nutrients to develop itself and live, but it will recognize that at some point it will run out of calories and die. So it has to do something about it. What it does, is to develop leaves. These leaves collect the sunlight and this way, the plant has a constant and continuous source of energy/calories. So it can keep on living.

              Society has a very similar problem. We have oil, but it is limited. We can use it to develop, but eventually we’re gonna run out of it. So we have to do something about it. Just like a plant, we develop solar panels to collect the sunlight, so we have a continuous income of energy. This way we can live waaay beyond the time of our starting bonus.

                You can’t replace petrochemicals with sunlight, let alone convert everything that runs on some form of oil product into eg. electric - not nearly enough rare earths in existence, and hydrogen is not the solution either for the majority for a variety of reasons (starting from ridiculously low energy density to being absolute ass to store)

          Crossing large spans of water was very dangerous, because of storms, getting lost, running out of food etc. Nowadays, crossing large spans of empty space is also very dangerous, but the dangers are a bit different. Regardless, I can see many similarities between crossing the Atlantic ocean in the 1400s and going to the moon 500 years laters.

            Although you could travel the land. Perhaps not cross the Sahara but if you lived in the Roman world, you could quite easily take some years to walk off the edge of the map and just explore. There would of course be a good chance of death from illness, animal or person, but equally like today, you may also meet plenty of kind people who would let you stay and maybe even share their knowledge of the area and culture.

                It was a lot later (1300s), but Ibn Battuta seems to have done just that. Guy leaves Morocco and just keeps going on and on, till he ends up in China. Though perhaps even more incredibly he actually does come all the way back. The historicity of his accounts is disputed and maybe only a part of it is true, but even if he only got as far as India, I still find it fascinating to imagine doing at that time.

            there is an infinite difference between “you can technically do it but you’re 99% likely to die” and “you literally cannot even reach the edge of the atmosphere without a vehicle engineered and built by 5000 people”

              You’re right that there are many big differences. Launching a rocket into space could be compared with building a major cathedral back in the day. People did both, but not very often, because those projects are very demanding. Ships were also super expensive, but we built those all the time, so obviously the requirements weren’t quite as high.

              Also attitudes have shifted quite a lot in the recent centuries, so losing a few sailors isn’t quite the same as losing an astronaut. Nowadays, safety is taken a lot more seriously which makes the project even more expensive.

          Oh no you can’t. Building a ship that can cross the ocean (without you drowning first of course) is actually quite difficult. Not only does it have to be extremely durable, you also have to have a lot of knowledge to navigate. And then there’s the economic problems, like who pays for it, how do you get enough food, etc…

    I’m not so sure this is accurate, the Romans certainly knew of China at least, to them it was called Serica, and they believed in a Manifest Destiny myth that they would one day conquer it.

    Which would have been fukkin’ wild if it did play out, I think by that point the capital would have moved to Samarkand or somewhere else in Central Asia just to be able to maintain regulation over the silk road.

          Is it? Oh, I didn’t realise. I’ll cross that out.

          Yeah, it looks like the main evidence is that there’s a mention of a similar formation to testudo being seen in western China a couple decades later, and maybe some Roman-style fortifications. According to Wikipedia a large number of prisoners were sent to Merv somewhat nearby, so it’s all very suggestive, but definitely no smoking gun.

        Yup. Not because they couldn’t, but because they figured they had enough boggy northern European territory, and would rather spend resources on Africa, Persia or the Middle East, which had nice things they wanted.

    In medieval Europe, spices from outside the world known to Europeans made it there through chains of traders and were luxury items. (IIRC, a spice from what is now Indonesia is recorded as having been a gift at a wedding in what is now Poland in the 13th century.) I’m guessing the definition of “known to” in this post is similar: Romans had access (at a price) to goods from these places, though nobody from the Roman world had actually been there, or even met anyone from there.

    As far as the ancient European world goes, I think the furthest east they actually got were some sort-lived Greek-speaking states in the vicinity of India.

      People would follow the silk road sometimes. Rome actually had limited diplomatic contact with China, even. That’s not on the map, maybe because they didn’t really understand where it was, besides somewhere far to the east. I’m surprised SE Asia is on it, I’ll have to do some reading about that, but India was known even to the Greeks.

      Quality of information would drop off really rapidly with distance, though, since it was easy to make up a fish tale about what you saw in far-off lands. So, you find a lot of crazy BS mixed in with helpful nuggets in things like Herodotus’s Histories.

        The modern interpretations have included Orkney, Shetland, Northern Scotland, the island of Saaremaa (Ösel) in Estonia, and the Norwegian island of Smøla.

        By the Late Middle Ages and the early modern period, the Greco-Roman Thule was often identified with the real Iceland or Greenland. Sometimes Ultima Thule was a Latin name for Greenland, when Thule was used for Iceland. By the late 19th century, however, Thule was frequently identified with Norway.[6][7]

        https://en.m.wikipedia.org/wiki/Thule

        But yeah they were aware of things beyond the limits of their maps. So idk id this is more accurately “roughly around the limits of roman maps” instead of “the area the Roman empire ruled”.

        Tacitus for instance talks about the Fenni and the romans definitely visited and knew the Baltic Sea, but there probably wasn’t a whole lot going on around 100AD that would’ve been of that much interest to the romans. Fishing and relatively poor trading (by Roman standards).

          Right, I forget that the concept of Thule changed over time.

          And yeah, they were definitely aware of the world outside of their own cartography. I believe there were definitely accounts of them attempting to journey on the Baltic Sea, but I don’t recall it ending well.

          Similarly they also were well aware of the Chinese. It’s disputed but Roman ambassadors or merchants made it to China at one point. I believe in 166 BCE a crew went over there, but unfortunately they likely returned home at a troubling time when the Antonine Plague was spreading.

          Might be wrong about some details though.

      The post says “known to” rather than “visited”, though it’s not clear what that actually means.

      But there’s very little in the way of written evidence of the Suomi until way, way more recently than the Roman Empire. It makes sense that they wouldn’t be particularly interested in an area that was sparsely populated, not technically sophisticated, and had little in the way of then-usable resources.
