I really love those ancient and medieval maps that get the mediteranean coastline so wrong. It's really funny seing the Adriatic sea extended into the Alps region, or the Southern Balkan Peninsula and Asia minor being completely square.
"Men died just to explore the same region we can now navigate with our computer mouse" Right in the face of "the decadent society technology has turned us into".
+Rubén Pérez how is it any inferior that we actually manage to turn such a treacherous task into something so easy and doesn't need people to die to do? I say /r/im14andthisisdeep and get over yourselves.
+Rubén Pérez But isn't this what the explorers(the good willed ones) would have wanted? to have the general populous share what they discovered, see as they did?
al-Khwarizmi was merely an Arabised name, but he was actually a Persian from Khorosan, in what is now Uzbekistan. BTW, I love all of your videos, and it's always a pleasure to watch one.
Interesting to note that in the "T and O" map at 4:05 each of the three masses of land are assigned between the three sons of Noah: Sem, Cham and Iafeth. The influence of religion...
A key development was to accurately measure longitude. Latitude was easy to determine from the height of the Sun at noon, or the stars, but your east-west displacement was more difficult. If you knew what time it was at your home-port when it was noon out in your location on the open ocean, you knew you had 15° of difference for every hour of difference. But accurate clocks, particularly those that could work on the pitch and roll of a ship, were difficult. A prize was offered by the King of England to devise such a clock, and that was first won by James Harrison, in 1700. The Europeans could now venture for weeks, out of sight of land, and not get lost. Dependable travel caused exploration, trade, and conquest to explode.
***** He could've easily been bi-lingual. Since he lived in Baghdad, which was near the Arab border with Persia, many of the cities inhabitants would have spoke Farsi and Arabic, not just one. And there are a bunch of nations, where being bi-lingual was huge.
That map, the Cantino map is Portuguese, and has got flags in the Portuguese cities and has got the line of separation of the world between Portugal and Spain
I got to admit it, that Chinese stone carve map of the rivers in 3:22 looks like it was taken from space even though it wasn't. Look at that exquisite details!😮
I would love to see a more expanded video on cartography. I love maps, especially old ones that give insight into how people used to view the world. If you're ever up to it I'd totally watch a video that looks into either the entire history, or perhaps just some important moments, with more detail. Love your vids btw, i hope this channel keeps on growing!
+Sir Vladimir Pootis “Pingu” Almost all (if not all) educated people of the period were aware of the earth's shape. I'd guess that uneducated people probably fell for the church's suggestions though. en.wikipedia.org/wiki/Myth_of_the_flat_Earth
MisterTalkingMachine The Church never suggested that the Earth was flat. The Church only suggested that the Earth was the centre of the universe - geocentrism. Big difference.
Stephanus Tavilrond No, ancient Greeks and Egyptians suggested that the Earth was round, but in most of the middle ages people thought that the Gibraltar strait and the continental extreme east were the edge of the world.
I do have to wonder: how would we react if we never went on an age of exploration but still invented satellites that suddenly made us realize there was another continent? I know, it's border-line impossible, but it's still an interesting idea...
I wouldn't ever think I'd be watching video about the history of cartography in youtube. So my good sir. You are doing awesome work keeping this entertaining and educating. Thank you.
This article is about the post-1824 measures used in the British Empire and countries in the British sphere of influence. For the units used in England before 1824, see English units. For the system of weight, see Avoirdupois. For United States customary units, see United States customary units. For Overview of UK and US units, see Imperial and US customary measurement systems. The former Weights and Measures office in Seven Sisters, London (590 Seven Sisters Road). The system of imperial units or the imperial system (also known as British Imperial[1] or Exchequer Standards of 1825) is the system of units first defined in the British Weights and Measures Act of 1824, which was later refined and reduced. The Imperial units replaced the Winchester Standards, which were in effect from 1588 to 1825.[2] The system came into official use across the British Empire. By the late 20th century, most nations of the former empire had officially adopted the metric system as their main system of measurement, although some imperial units are still used in the United Kingdom, Canada and other countries formerly part of the British Empire. The imperial system developed from what were first known as English units, as did the related system of United States customary units.

I m a bit sad you didn t talk about Portugal and the porguese discoverys and contibutes to cartography.... Portugal was one of the most important countryes that discovered the world by sea... We discovered Brazil, the path to India by sea, etc... I hope you make a video about this :)
its a thursday summer afternoon and im sitting inside, curled in a blanket, eating off brand coco puffs, and watchinga video about the history of maps.
HE'S ALIVE!! this video is excellent. I spent about ten minutes examining the map at 0:56. What is the name of that map and when was it made and who made it? (I'm sure the latter questions I could find out for myself once I know the name)
imagine throughout history we never knew what earth truly looked like until just decades ago in the 20th century we are the lucky ones who have opened doors into sciences and expanded upon the subject .. sure science is a vast endless topic with new discoveries made every day but i can confidently say that science has never before provided us humans with its benefits as it does today. The scientists of 18th & 19th century had certainly been the pioneers but they were the ones who had just scratched the surface but we have ripping the rewards and of course with out the 18-19th century pioneering scientists we would not be where we our today. Hats off to those brilliant minds
I have some questions at 6:02 1. Why does the world have a shadow 2. Sumatra is connected to Asia 3.Scandinavia 4. No Denmark 5. Why is Britain so close to mainland europe 6. WHAT are you saying and showing which map
I think it would be interesting to investigate about piri reis' map. I would really like a video about it. Thanks for all these videos, they're awesome.
Love the subject on this one. Not that I dislike your other videos. A follow up, would be a history and general explanation of GIS. This crowd should be pretty receptive.
"It would be hard to imagine people in the past never being able to see what the world look like" The same can be said to us, modern human, about Universe, or Solar system even. We're still not able to see what a whole Solar system exactly look like. We can only go by scientist's calculation, estimation and imagination. One day, future generation may laugh at us for some of our incorrect assumption.
@GeographyHub Could you please explain how in antiquity and even middle ages, people constructed maps? Because sure, now it looks easy to figure out the shape of for example Italy or even Europe (just use a sattelite or plane). I mean it is easy to tell the shape by getting an overview, by seeing it in it's 'totallity' from above. But how did they know italy had a booth like shape back in roman days? Even if u walk all around italy (to map it's boarder) as a Roman then it still seems difficult to map it in ur head or on paper. Or when u walk from Rome to Amsterdam, in those olden days, then it must seem like this big blob of landmass. So how did they get these dimensions, because those old maps in this video, especially about europe, are quite accurate
+strateeg32 If you can measure a distance, even if it's vague, and the cardinal directions, you can get an idea of the shape of a patch of land. For example, if you were to travel Italy all the way across in a north-west to south-east direction, and then travel across it on a south-west to north east direction, you would notice that it's much longer than it's wide. So yeah, measuring distances and orientations was big part of it. Circumnavigation was also a common method of mapping afaik.
You should have takl about the military purpuse of maps for exmple the ferraris map in belgium or the french Sassinis brothers map. And Erathostène d'Alexendrie is the one who prouve that the world was a shere.

I really love those ancient and medieval maps that get the mediteranean coastline so wrong. It's really funny seing the Adriatic sea extended into the Alps region, or the Southern Balkan Peninsula and Asia minor being completely square.
They're maps ran on Minecraft logic back then.
Well, basically there once was a sea where now the Alps are. But that's millions of years ago, of course ;)
+Andrew Lowery XD
Tbf, many medieval maps weren't trying to be accurate depictions, just general ideas of things (and occasionally they actually weren't even maps)
I expected to see the map of Piri Reis, since it is a topic of discussion for a long time now.
I've always love maps and looking over old and period maps. The stylization (which still occurs), the accuracy, the guesswork, all of it.

Implementation[edit]
The Weights and Measures Act of 1824 was initially scheduled to go into effect on 1 May 1825.[3] However, the Weights and Measures Act of 1825 pushed back the date to 1 January 1826.[4] The 1824 Act allowed the continued use of pre-imperial units provided that they were customary, widely known, and clearly marked with imperial equivalents.[3]
Apothecaries' units[edit]
Imperial standards of length 1876 in Trafalgar Square, London.
Apothecaries' units are mentioned neither in the act of 1824 nor 1825. At the time, apothecaries' weights and measures were regulated "in England, Wales, and Berwick-upon-Tweed" by the London College of Physicians, and in Ireland by the Dublin College of Physicians. In Scotland, apothecaries' units were unofficially regulated by the Edinburgh College of Physicians. The three colleges published, at infrequent intervals, pharmacopoeiae, the London and Dublin editions having the force of law.[5][6]
Imperial apothecaries' measures, based on the imperial pint of 20 fluid ounces, were introduced by the publication of the London Pharmacopoeia of 1836,[7][8] the Edinburgh Pharmacopoeia of 1839,[9] and the Dublin Pharmacopoeia of 1850.[10] The Medical Act of 1858 transferred to The Crown the right to publish the official pharmacopoeia and to regulate apothecaries' weights and measures.[11]

Wow, I didn't think writing codys name backwards into my death note would bring him back!
Cody. What do you study/have studied in college ?
I'm pretty impressed how accurate the European part of the map was at the beginning.
This was really helpful love all the detail and hard work you put into these videos it really helps me with homework and things
the ending music reminds me of early civ games
I like this channel more than Historyhub

I find this more interesting than I wish I did
This man is funny, he was so quick to shut down the flat disk theory 🤣😂🤣🤣🤣
Awesome. I've wondered many things this video discussed
I wonder, is the Phanis river on the Alixmander map the Volga? The Volga is very long and is the largest river that empties into the black sea.
No mention of James Cook :/
I keep trying to google how they actually mapped and this keeps popping up, I'm annoyed.
Love your channel!
What did you say at 4:30? Portal and short?
