So you are trying to tell me there were people that thought this was less reasonable than them actually transforming into other animals. Wild shit.

And here I thought it was going to be about a Korean emperor! Good video.

Before watching this, I guessed that Alfonso 10th ('el Sabio') of Castile was the ruler in question. I'd forgotten about Frederick - another European monarch deeply influenced by Islamic (particularly Sufic) ideas.

In many towns around Southern Italy, Frederick the 2nd has still got a strong cult status and almost venerated like a saint. He was responsible for building many of the best looking churches and castles in the area during his lifetime, his intellect and political acumen has made him a Renaissance man ahead of the time.

"How do you know so much about swallows?" "Well, you have to know these things when you're a kaiser, you know."

There's a podcast called the constant, a history of getting things wrong that does an episode on this

Lest that castle would become a constant pain in your ass

5:45 yay they fixed the ozone layer

5:22 people 136,000 years ago should be ashamed of inventing global warming

Are we sure birds don’t turn into different animals ?

Finally an explanation of how the african swallow could carry a coconut to europe

Guy liked birbs

This is a "classic" example of many score examples throughout history how the simple fraud and racketeering of supernaturalist-based religion(s); gangsters in EVERY WAY, SHAPE and FORM religion as we know it, completely RETARDED HUMANITY, (our societies, peoples, politics, countries, progress, institutions, everything good or important) BY CENTURIES when, otherwise, everyone coulda, woulda, shoulda known better, amounting to all the relevant things needed to know reality and act, think and behave accordingly. The sheer fraud of supernaturalism (organized) theistic religions is actually peerless amoral opportunism predicated on fraud, throughout the relatively dismal past, now and inevitably, unless we stop it, into the innocent future, ad infinitum, . . . DUMP supernaturalism. Embrace, instead, (religious) Naturalism and the entire, ages-old, overwhelming superproblem of all time is solved, best and permanently, imho.

I do falconry. I give my birds opium so they always come back.

I get it that we have hindsight and everything BUT couldn't you just look at a bird and see how fast they travel without any obstacle in the air. Then from a thought that maybe they could just keep going for several days or weeks till they're in a different region?

European birds or African birds ?

what's interesting is that gamekeepers in Europe were puzzled by the occasional stork flying with embedded arrows (from attempted shots while flying in Africa). They had to come up with an explanation for that.

aahh a bird enthusiast, my kind of person

Fascinating.

my problem with this is twofold: first, by "scientific mind" you mean he was on the spectrum. if i was a medieval peasant and the emperor was rambling about stuff of no consequence to me i'd probably think "that makes sense" but wouldn't really care because it makes no difference to me. the next time i hear a bard talks about birds turning into deer, i would just go along with it, i wouldn't go "akshually..." even if i didn't believe it to be true. my first point then is that it is not that nobody believe him, but instead, that nobody cared. My second point is, what was his hypothesis? how did he test it? where's the data? making wild guesses and getting it right by chance isn't "science", so you should make sure to include the data the emperor collected and how he analyzed it next time!

I enjoyed very much this video, thank you!

If he had put chipper rings on a few thousand captured birds, he could have proved it.

You mean people were that stupid back then? You don't need a scientific mind to observe the obvious. This is just another one of those BS articles trying to elevate so-called 'science', which is satan's invention. You can take the science and stuff it up your backside.

Frederick II definitely counts among the most brilliant minds of all times! And definitely not only because of his "De arte venandi cum avibus".

This is not unreasonable. Maybe at the time insect and amphibian metamorphoses had been observed already.

That was one detail I don't recall from my friend John Chodes's play, _Frederick 2_ .

To this day we still don't know where male birds be hiding their weiner

Very interesting video! Thank you!

Relying on earlier "authoritative" sources? Just what pseudo science does today.

To be fair, people would have been familiar with animals that _did_ hibernate, so that one's not too unscientific: hedgehogs, bears, doormice, ladybirds, some frogs and toads

“Calculated to frighten people” is one of the most pathetic and funniest excuse for arresting someone on false pretenses I’ve heard in my long life, whether or not it actually happened. Very clever way to make the hat popular had it occurred. As a lifelong student of history and human behavior, as well as a person obsessed by research, I bow to you for coming so close to tracking down the original article.

Wonderful video. Such a brilliant man. I wonder how many things were discovered and lost forever until rediscovered thousands of years later. I do love the image of geese falling from goose trees in your video on geese in Scotland.

The irony is that these geese are fish. So are all birds, all reptiles, amphibians and mammals.

So…geese are vegan, right?

If only everyone had been as critical of Aristotle as this king, some of Aristotle's insane ideas about slavery and abortion might have been avoided. I never knew about this until know, so thank you!

I like the quote at 7:25 “When I eagerly investigated this matter, I learned that miracles always recede further into the distance.” AKA, when you look into peoples impressive stories, they always conveniently actually only heard it from someone else lol

this makes the first gag of MP and thr holy grail even more funnier

Really fascinating, thanks!

Some people has the ability to observe and understand what they see. They are few and far between.

Having grown up on the Mississippi river in Tennessee, it never occurred to me that bird migration could be a mystery. I grew up under thousands upon thousands of doves, ducks, and geese heading south every winter and filtering back north every spring.

New to your channel. Big fan! Thanks!

If you want to learn more about the theories Frederick was up against you can find them in this playlist: kzfaq.info/sun/PLfp1VB3Lm4ImMWsxXFgtLyjIt4S8FZ96F&si=bNjjZo2N4RdZD404

Frederick's assessment of Aristotle is spot on ! Aristotle was basically an "encyclopedia-ist". Aristotle only collected and compiled prior knowledge, as do most encyclopedias. As such, summation errors occur, as many complain about in Wikipedia. All encyclopedias contain errors, when trying to compress data, where subtleties of a topic get lost. This is not restricted to Wikipedia. I've found many errors in old "paper" encyclopedias before the Internet even existed.

One of many reasons why the Greek guy is called Errorstotle.

I'm trying to learn how to watercolor and I find inspiration in the most serendipitous ways. I was watching this episode and got the impulse to try and paint birds during migration😂😂 Love the channel and videos.very nice! Greetings from the U.S.

I really like the style of the presentation. Which software do you use?

He’s the one that worked out the air speed velocity of the European and African swallows, which carry coconuts. 🥥

The understanding that the lead bird gets exhausted is such a giant leap towards fluid dynamics/flight mechanics. Imagine if he had been taken seriously. Gliding could have shown up much sooner.

Im gonna need more information on this transmutation into barnacle geese theory, asap

This is what happens when you science when you oughtta emperor
