There's another channel called ClickSpring where the guys shows how the ancient Greeks could have conceivably created a surprisingly accurate dividing head using nothing more than hand tools, which would be required to accurately space the gear teeth.
Yeah, been watching the proccess. Pretty interesting
Ive been watching him for years
This is a masterpiece of engineering, and is exquisitely beautiful.
What an amazing mechanism! To think this was originally made all those years ago, I really want to go back in time and see how they made such delicate and precise components!
What a mastepiece! Not only the original mechanism but the replica of it as well! thank you Sir! As a Greek, I'm grateful to you!
I love your videos. I don’t know anything about metal working or machining, but I like learning new stuff, about most anything. Your videos are an inspiration to me, a 3D computer graphics animation artist. I love watching a master at work!
Very interesting video. Nicely illustrated and narrated. Thank you
I knew the story of the Mechanism, so this title caught my eye. Fantastic vid. TYVM
Wow! This is something different !
What is even more astounding is that such a device was in use 2000 years or more ago. Ancient craftmanship not only in creating the cogged wheels, but also the bolts that hold the device together. How was such precise engineering achieved? How did they create the absolutely flat places of brass from which the wheels were made? The knowledge of astronomy was incredible - long-term observations taken, corrected and verified over many decades. This points to a civilization capable of employing and maintaining guilds of master craftsmen and astronomers - all taking lifetimes of dedication in building a knowledge base. Who knows what was lost in the burning of the Library of Alexander.
this should get more views . amazing thank you so much.
Incredible. Now imagine this being made thousands of years ago
Well done - absolutely brilliant job. I knew that somebody other than me would tackle this incredible machine and its stunning planetarium eventually!! Bravo. 😊👏
Thanks, Dave! We’ve been fans of your wooden version for some time too.
i think the best way to recreate this type of mechanism, is to use the ancient techniques of manufacturing, by the way, great job
yay love this clock
great video.. Thanks for sharing
Thanks, glad you enjoyed it!
My all too soon late father (1904 - 1954) was an educated watchmaker, and he would have loved to see this mechanism explained! But he managed to see the, still most precise mechanical Clock in the World (Guinness)! "The Olsen Clock" in a side room in the Town Hall in Copenhagen.
Great work - much respect ! Just the backside confuses me. I just saw one display - but there should be a second one. - take a look to the last “click spring” videos
Great video, but it feels too short!
Amazing work. Any chance one will be for sale?
I want copy one of this. Make More !
A Master Work!❤ model is different to movie " Indiana Jones and the Dial of Destiny" I am intriged how they reconstruct this artifact, original heavily and very damaged for rust. Anyway, an lovely intriging history!
Great! Such a nice work and reproduction of this artifact! love it
Hi Nora, this reproduction is the same scale as the original mechanism. Thanks for watching!
@@chronovaengineering Thx 🤗
What’s amazing is how archimedes made the antikythera thousands of years ago with no lathes no modern machines that we have now. That’s amazing
At 1:55 that would be an perfect spinner for a board hame :)
To find such a technology is like finding that the Egyptians had jet planes during the early part of their civilization. Clearly, the development of technology was an early feature of Greek civilization and likely many others. More of these sorts of discoveries will come forth and we may well find that pre-dark-ages civilizations were far more sophisticated than we ever believed possible.
I wonder if the pin-slot-gear mechanism made the Greeks question geocentrism, or if they were excited that it only took a few components to emulate the world as they saw it
What dose its do when it all said and done?? .. dose it predict the sun for crops ??and if so dose the replica predict this also or is it all for show
Hi EaStxVaNxiNc, it’s a calendar for predicting the position of the moon and planets, so it can be used to forecast events like eclipses. It is accurate but it’s not clear exactly what the broader original applications were.
I could handle a 30 min video easily!
what are the top ten uses for this machine, i am sure it was worth millions during the time period
@@tooltime9260 yeah, actually figured, some ancient buildings are very well made, as one who studied engineering, i guess those people in the past thousands of years had complex justice, military, and scientific systems for them to afford such grand projects which could span more than a lifetime to complete even with today's knowledge and technology
goosebumps train arriving
So the mechanism is basically a ginormous tourbillon...
Yup, they knew what they were doing
It's an interesting video and topic, but I'm only halfway thru and I've had to turn the volume up to hear the speaking and down when the music swells several times now and it's just not good. The music is definitely too loud, so I turn it down. But then when the narration comes back, it's too quiet.
it would probably take a day or more, just to make a correct gear spacer,for the original mechanism. If there is any remote evidence for alien intervention , the Antikythera Mech is probably it. Not only for the complexity, but for the aligning and timing of stars, right at the correct-ish time.
A much better proof of exterior intervention is the perfect anatomy of our feet. If they were designed differently we wouldn't be able to wear shoes and we would have to walk barefoot on the pavement.
@@christianbarnay2499 If they were "designed" better, we wouldn't need to wear shoes. Our foot anatomy is the opposite of perfect. It's a jury-rigged set of rubbish compromises, based upon unpromising starting material.
Its just hard to fathom how the ancients could create such a device.The more i learn , im lead to believe they were more capable and knowledgeable than we think..As far as pure imagination they may have been more creative than we are today especially the fact that they didnt have the distractions that we have today.
I’d love to buy a 3D printed replica
How were leap years accounted for?
There are four dials missing from the back side. EDIT: nice job, but how is this handmade?
Yes. The Clickspring youtube channel produced a stunning complete mechanism. Hand engraved it to. Exceptional skills.
It's also punching out the discs,and measuring them to put sixty cuts per cog accurately per size of cog. The whole mechanism makes human invention a contradiction.
Wonderful work and good to see the GHT VDH in action. But puzzled by the "handmade" label.
Thanks, yes the VDH is super useful. 'Handmade' referring to the use of manual machines rather than CNC.
Do you think the ancient Greeks just tapped their bare hands on a rock and out popped an Antikythera?
Α ρε Ελλαδαρα...
How to do this without machines? Unbeleaveble.
The technology came to them from Atlantis, and I'm serious.
To agree is simple, the facts that the fallen hosts, Demons are the real truth. they rebeled against God (Eloah) and came to the women on Men (Adamic Creation) not previous humanoids by the demons themselves (Neanderthals, Dennisons, and later Nephilims. It is historical that they taught many things in our common life and science was one, and engineering, so I would imagine they also taught this type of technology. Not in an evil sense, but they desired man to be self-supported and not follow the One True God, and as you can see in the generations of this world they did very well. Very few follow the New Moons, Sabbaths, and Gods reverence...
Is this why they call them 'planetary gears'?
Who’s here after the Battle of Syracuse in 213 BC?
What is really amazing in all this Engineering is that is precisely maintained the Conjuction of the New Moon cycle which determines by God our months and years according to the Ancient 2nd Temple Calendar in use to the time of Yeshua (Jesus the Christ) and the Apostles to be used to decide proper observance of the Annual Feasts of God and Sabbath and & New Moon days to be honored. Even in today's modern Churches of God, they cannot determine this with the exception of The Christian Churches of God whom follow the New Moon according to the proper conjunctions and not of the Hillel II postponement system. Absolute unimaginably intelligence in ancient knowledge.
It is only assumed to be Greek but the phoenicians and the sea peoples also plied the Mediterranean in trade there is also evidence that the Egyptians traded throughout the area. Even if it was proven to be a greek ship its cargo could be from anywhere in the then known world.
And all this engineering could've been avoided... if they'd just used a heliocentric model So it's just a clock with more dials
It's not a bad version. Not terribly accurate and missing a lot of important detail/functions. Involute gears aren't ideal either. Clickspring will produce by far the most accurate represantion since the machine was originally manufactured
Thanks for your input you melt.
Agreed
I watched this whole video with one question in mind that was never answered: what was it actually used for?, the mechanism was a calender/ clock that depicted exact positions of celestial bodies, one could argue it was for sailing, but considering you'd only need the positions of sun and moon, and with a protractor you could find a heading. what would be the use of the rest of the data produced? answer: to sail a ship on a flat bed of water you only need 3 points of reference where th sun is in the sky, the angle of trajectory, and time of day. but space travel you need multiple more points to refer to for direction ie the sun, and planetary location and time of year from planetary alignment
The original device displays the known celestial objects as they appear on the sky and not due to geocentrism. The only difference is the complexity of retrograde motion.
A machine older than christ to read the planets highly sus of all the erased history
So, does this mean that the earth is actually flat after all and that NASA is just a big cash cow?
The Flat Earth theory is based on the Book of Enoch and the Book of Jubilees. The four seasons, the Elements and all were called upon by God (Eloah) through portals and you had to travel through the seasons and at the end you hit a tme warp to continue back into the beginning season, and since the modern navies we discovered the horizon and the spherical continuation of the planet, and now with our pictures from outer space by telecopes and satelites, we now know definately the world and planets are spherical and not flat or ovalic like presumed. There was theory to it for ancient mankind, but as we grow and learn we depart from our youthful perceptions.
The Greek didn’t have all these tools, or did they?
I think im one of the few people who actually know what this is
How odd is that, sure a lot of sevens floating around here, I wonder if it was the number behind it's design, had to stop it @1:42(=7), on this video that is 7 minutes and 16(=7) seconds, where we see Spica at 205(=7) degrees, Antares at 250(=7) degrees, and Hydro at 340(=7) degrees, all hiding the number 7, even in the comments, a 70, this will be 71, too bad, but 6 is good, 3 create a 60 degree triangle, joining the long end to the short end, 3x7=21, 60 minutes in a hour, 60x3=3 hours(60 60 60=666) to add to the 21, triangulating the day, but what do you do for 60 minutes every 7 hours, I known, 60x7=420, LMAO, Triangle up, triangle down, means male & female, which is Virgo, Latin meaning Virgin, a Man/Woman, 'vir' is Latin Man, 'gyne' is Greek Woman, play "Boy/Girl" in reverse, you hear it echo Virgo, that rules 3 weeks of September, (3x7), septem means 7 in Latin, and hiding in the center of 7 is Eve, between the S'N, SIN Eve, in reverse, echoes "Venus", who hides 7 weeks behind the Sun, that is tilted 7 degrees, giving it a 79 year Swing Dance like Shiva, the Hebrew word for 7, a number associated with the Moon, that can be echoed with the words "New Womb", and "Her The Priest" will echo "Jupiter" played in reverse, and as we see, Mercury and the Sun at 160 degrees, another 7, a number Mercury like too, make 7 triangles every 7 years with 22 retrogrades, 22\7=Pi, each retrogrades is 3 weeks(3x7), 120 degrees from the last, caused by Mercury's 88 day year, and having 6 days of sunlight every Earth year, 7 days if you count Mercury's mid-day Double Sunrise as an extra day, doing all of this 7 degrees above out path around the Sun, and the 79 year cycle of the Sun is found with Mercury too, when you place Mars next to Mercury, every 79 years they show up together on the same day, and the 7 is friendly with Mars too, retrogrades 70 to 79 days, every 707 days can be found back at the same spot in the sky, and like Venus retrograding 40 to 43 days every 77 weeks, both conjuncts 3 times in 9 months every 77 months, 7+7=14 and 14+77=91, the number of days in a season. The Moon has a 3 year rhythm, 1st year is 12 full moon, 2nd year is 12 full moons, the 3rd year is 13 full moons, a total of 37 full moons, the 4th year makes it 49 full moons, or 7x7, the number we see adding a new day every 4 years for 2,160 years, 2160\4=540 added Leap Days, 540\7=77.14 of weeks, count 70 days from the summer solstice, August 31st is 183 days from February 29th on Leap Year, 183x2=366, September 6th is the 250 day, 77 days from the Summer Solstice, 115 days left in the year, both are 7, which is 16 days from the Fall Equinox, 106 days from the Winter Solstice, 169 days from the Spring Equinox. Shiva known as the Destroyer, has a cycle, every 2,160,000,000 year, Did I tell you, play Seven in reverse, you hear Novus, meaning New, play "Novus Universe" in reverse, it echoes "77", what Shiva does on his cycle, creates a New Universe. Even in ancient times The 12 and the 60 came from the design of your hands, you have 3 phalanges on each finger, and 4 fingers, with the thumb you count each phalange until you get to 12, keep track of each 12 with the fingers of your other hand, 3x4=12 and 12x5=60. Here's a little true gnosis, Noah's 950 year age, seems to match the Sun's 79 year swing cycle, 950 ÷12= 79.16666666666667. 12 Full Moons a year. The Sun is tilted like Earth, just not as much, the Sun is tilted 7 degrees, the Earth take 365 days to complete a cycle, the Sun takes 79 years to complete, as this tilt creates seasons just like Earth, 7x4=28 the number of days it spins at it's equator, The solar wind is a stream of charged particles coming from the Sun, that changes every 7 days, but the belly of the Sun, not the equator, spins at 25 (2+5=7) days, slower at its poles, 35 days at each pole (35+35=70), we see the same number with the cycling Moon, we have 35 minutes of Dawn, 35 minutes of Dusk, twilight hours is 70 minutes. If you take an image of the southern sky with the Sun, every day at 12:00 noon for a year, lay them over each other, the Sun draws out an 8, the Equinoxes crosses at the center. The equinoxes does have the same weather, the 3 Suns/Sons or seasons. The loop of the 8 at the top is bigger then the bottom, known as the Big and Little year, each with it's own king. The 7 is the number found with the spin of all the other planets too, and tied to leap year, and the Dog Star Sirius, which seems Not to spin with precession of the equinoxes, it spins with Earth's 365.25 year, drops below the horizon for 70 days, returning with the seasonal floods, like Venus but better, the Morning and Evening Star on the same day for 40 days, 40 being the number of days Venus retrogrades, the closes you get to the center of the Sun's poles, the slower it spins, could it be 40 days too? The number 7 was important to the ancient world too, used it to create their calendar. Old Assyrian calendar. Contrary to Old Babylonian practice, it is generally absent from loan contract dates, which prefer weeks, months and years. Based on lunar months and the solar year, the Old Assyrian calendar uses a quite unusual division of the month into weeks that might have been inspired originally by the phases of the moon, starting first with the full moon, šapattum, also used for half a month, and then with half a šapattum, corresponding to a week of seven days. I see where Septem, Latin 'seven' came from. I recall Irving Finkle taking about a 50 day/year calendar. 365.25 ÷ 50 = 7.305 - 1 Year 7.305 × 7 = 51.135 - 7 Years 51.135 × 7 = 357.945 - 49 Years 357.945 + 7.305 = 365.25 - 50 years You see dividing any number by 7, a set of repeating numbers after the decimal point "714285", which is 5 ÷ 7 = 0.714285714285714, its in the numbers, 7 is one week, 14 is two weeks, 28 is four weeks, a total of 49 weeks, the 5 is for the 50th, 49 × 7 = 343 343 + 7 = 350 Leaving one šapattum (New Moon to Full Moon) to complete the year. The moon has a 37 full cycle, first year is 12 full moons, the 2nd is 12 full moons, the 3rd year is a 13 full moon year, the next year will be back to a 12 full moon year, 37+12=49 full moons (7x7). You could say, the 50th full moon is the Leap Day, 49 full moons is 4 years. Blue Moons happen about every 2 1/2 years, caused by the 12 +12+13 Full Moon cycle, adds an extra moon in the 3rd moon cycle, 7x13=91, the number of day in a season, every 19 years, a Full Moon on the 304th day of the year, (3+0+4=7), we call that day Halloween, every 19 years, a month without a Full Moon, known as the Dark Month, in February, the month that we add an extra day, after 49 Full Moons, 7x7, 19 years is a season of our 7 degree tilted Sun, like Shiva (7), giving it a little Swing Dance, that takes 79 years to complete. You see the same set of repeating numbers after the decimal point, when you divide any number by 7, "714285", which is 7 one week, 14 two weeks, 28 four weeks, which is 49 weeks, 5 would be the 50th, the start of a new.
clickspring
Un- f***ing- believeable.
This object is proof that the earth is the center, but you gave the wrong animation to accompany the heliocentric opinion😅
Horrible music
Do you know why I stopped watching, and asked KZhead to not recommend this channel? Because the damned music is so loud I can’t hear myself thinking!
Same
Oh boy I'm so corporately inspire-motivated from this generic non-inspirational unmotivated I need to throw bonsai kittens to the moon! Dyn NAAAMMICCSS!!!!!!!!! silent silent DYNAMMICCSS!!! ssshhhhhhhhhhhhhhhhhhhhhhhhhhhhh DRAMATICCCCC!!! Motivate motiveate inspried inspired!!! where are the bonsai kittens??
It's so sad how much human progress has been halted due to religion and war and bigotry... The things we could've achieved, the life we could be living if only science through the ages had been allowed to flourish.
Sorry but click spring does it better!
It isn't a competition as far as I know.
Both wonderful, the more the better.
Clickspring still hasn't finished it.... 6 years later
How the Ancient Greek made this kinda mind boggling mechanisms is beyond me. 🤷🏻❤ I was redirected to this Chanel by Clickspring?? Whatever his name he uses I must pay my respect and thank him for this. For this moment I would like to thank this channel for this beautiful piece of a genius piece of art and sharing this with me. 👍👍
Well how the hell is it possible that this was made so long ago sure with modern day tooling and precision but back then something is clearly missing from the picture
If you want an in depth look at the process and methods used, check out "click spring" and his KZhead he made a video series on the topic. He made a lot of the tools and put an extreme amount of thought and effort into how it might have been accomplished originally. His original and the example shown here in this video are both incredible and thought provoking.
Something is missing indeed...
The first clocks were made circa 1300, the first metal mill 1818... What's missing is that we think people in ancient times were monkey's barely learning to walk upright. The Greek's invented quite a bit of the philosophical, mathematical, and scientific notions we still know are correct today, so why is making gears by hand so crazy.
As Chronova Engineering has pointed out, Clickspring has done a very in-depth series on making an Antikythera Mechanism using more and more era appropriate tech, including making his own files by hand, and then moved to hand filing the teeth, laying out the teeth with a hand made precision dividing plate. This video is the start of the series ( kzhead.info/sun/gLBtpNuXjKynjX0/bejne.html ). It is doable, we just need to think differently, and take a lot of care and time :) All the Best.
The discovery of the mechanism certainly opened up discussions on when such meticulously precise engineering was possible, and it changed preconceptions about the capabilities of ancient craftsmen and of peoples understanding of the solar system. I can't help but wonder if there are other such mechanisms awaiting discovery, perhaps preserved in better condition, and what they may tell us about the people who made them.
