The Antikythera Mechanism: A Shocking Discovery from Ancient Greece.

As part of an international team, Dr Tony Freeth has been a central figure in an extraordinary voyage of discovery: every new revelation has reinforced a sense of shock about this highly sophisticated ancient Greek astronomical calculating machine. It is one of the true wonders of the ancient world.

Whenever I fall asleep listening to videos on YouTube, I always wake up to this lecture.

Many times this machine's ancient origin was debunked by govt reps. But the research done by this man is good.

An outstanding presentation by Dr Tony Freeth.
Imagine coming across a poster advertising the coming lecture at Stanford University....
Very few apart from some very deep Science students would give it more than a passing glance.
Yet I wandered across it quite by accident - a casual browsing not even supported by a YouTube Algorithm - and I stayed for 1 hour and 48+ minutes.
So I can imagine that if an eminent scientist and a relative philistine like myself were to be seated together at this lecture we would rise together in enthusiastic applause at the end of it.
I am going to have to think about that a bit.
"You don't just make progress in science by getting everything right. You make progress also by getting things wrong in an interesting way."

Dr. Freeth, I've followed this since 62, when I arrived stateside, having been overseas, "navy brat", was apprized of it then, in Greece, saw an article regarding it mid sixties, and have heard here and there, hints. I'm a mechanic of sixty odd years, and would say it was a good quality working man's tools, as I've made myself, along my way to master machinist. I was five seeing it first, and was truly shocked when I ran across this, not having heard anything for a long time. I think you've done a masterful job, I was amazed decades ago, and again, in my teens, but I've always put it in context with "Hero's steam toy". I've seen a couple other examples of fine detailed machine work, from that time, but as you state, bronze worn out or broken, was recycled. I've made dozens of "engines" for engraving dials, or wheel faces, laying out by degrees, and even mils, for artillery purposes. Thank you for a great presentation, and great work in teasing out all the details, so intricate and and brilliantly discovered.

An extraordinarily well-constructed lecture about a complex device that describes the very complex motion of the moon and visible planets in the sky.

Just enough explanation of how gears work for those of us who are not engineers, just enough explanation of the orbits of the moon and planets for those of who are still learning astronomy, and just enough about the history of astronomy to know what was known when in antiquity.

Extremely well done. Both very educational and very entertaining.

This is absolutely fascinating. Thanks to the persistence and techniques of these brilliant scientists for pursuing this wonder of the ancient world! Their brilliance is only rivaled by the ancients themselves.

[rogerbibeau]

I stumbled upon this completely by accident. I've been interested in this device for decades since first hearing of it, collecting many documentaries. This is, by far, the most scholarly video I've seen on this subject. With many times feeling like I was riding down a steep hill in an out-of-control stagecoach trying to hold onto my hat, trying to keep up with each explanation. Simply outstanding presentation. Completely dazzling to hear how this mechanism came into being.

Not wanting to sound condescending, but I think I'm most impressed, besides the obvious, to see almost 4mil views. Normally, I guess I would have expected only hundreds of views about something this academically oriented. This gives me hope on many levels. Some brilliant comments.Thank You.

Incredible reconstruction, it just goes to show how intelligent ancient civilizations were. Let's not forget to thank all the people involved in this project, they're all geniuses.

As a gunsmith and machinist I’m amazed by the precision fabrication skills and tools clearly required to create this machine. I suggest an astronomer collaborating with a jeweler of sorts made this as a team. Indeed, I’d further suggest that a metallurgist and a chemist may have been on the team as well, since it appears that the machine’s alloys may be unique, and that some pretty fancy lubricants were needed to ensure smooth functioning.

hello fellow struggler, in this dark world, i thought i'd let you know that God loves you and to love yourself always.

[paulitza]

This is absolutely fascinating and I cannot express my gratitude to the fullest by just saying "Thank you for sharing such interesting information."
My appreciation for such findings were kindled when I attended Melbourne University, and was welcome into their History and Philosophy of Science department briefly, under the tutelage of Monica, whose inspiration led me to appreciate antiquity ...
Life is much too short to fully appreciate our ancestors and their achievements.

A really enjoyable and educational talk. Thank you Tony Freeth and much respect for your scholarship. If more academics had your skill of conversation and ability to convey insights, the world would be a better place.

[davidgrest]

One of the best videos on the internet. Thank you so much for your painstaking research.

[mutualbeard]

Wow! As a child in the late sixties/early seventies I avidly consumed every book I could find on underwater archaeology. The account of the finding of the Antikythera wreck with all it's treasures and it's lumps of corroded and encrusted brass cogs was spellbinding. It seems that the brass cogs are the greatest treasure. To listen to this smart man, Dr Tony Freeth, explain what he and others have learnt is a real pleasure.

What a fantastic in-depth lecture, really amazing stuff. One has to wonder at the level of sophistication of the ancients, what other wonders have been lost to time. They have been greatly underestimated.

[liammurphy]

When this object first came to my attention in the 6o's there was a lot of guessing and theories, I'm so happy to have lived long enough to hear some definitive statements regarding it. Astounding work by all concerned and a marvel that shows so very clearly the glory that was ancient Greece.

[Sapper-X]

Incredible detail and precision of the gear teeth on such ancient technology.
An absolutely mind blowing subject to study. Hat’s off to all involved in decoding the Antikythera Mechanism; geniuses.
From Australia.

Fascinating. My physics teacher in high school said repeatedly over the year, "The ancients were not dumb." How could they build something like that when they couldn't build the machine Babbage wanted to build?

[patricknoveski]

Just Incredible to think all these people put this device back together after over 2000 years under water. Amazing work !
