Abbreviated Transcript:

0:00:20 In his famous research paper "Gears From The Greeks" historian Derek De Solla Price put forward a stunning theory regarding the device known as the Antikythera Mechanism. That the origins of our modern day engineering achievements, what he called our "recent age of High Technology", could be found in this ancient device. He theorised that the profession of clock and instrument making had acted as a silent "carrier" of a larger, and much older technology tradition.
01:08 Clockmakers, he said, had played a crucial role in the emergence of our modern world, and that the clockmaking tradition itself, was part of a distinguished main line of technology that could be directly traced all of the way back to the Antikythera Mechanism.
01:25 The Ancient Greeks had written the original language of the mechanical engineer, and had left behind a record of it in this incredible device. A calculating machine, that used complex mathematics and precise engineering to model the Ancient Greek understanding of the Cosmos.
02:01 The phase of the moon, retrograde motion of the planets, and even barely observable details like the precession of the lunar orbit, were all modelled according to Ancient Greek astronomical theory.
02:23 Now I should point out that this is not the first time that someone has made a version of the Antikythera Mechanism, in fact far from it. There have been more than a dozen reproductions that I'm aware of, the most notable of which are the two constructed by Michael Wright.
02:58 But there will also be plenty of opportunity to investigate some of the construction, as it would have been undertaken but the original maker more than 2000 years ago. The data for the reproduction will be sourced from the latest research, mostly from the published work of Tony Freeth and his colleagues of the Antikythera Mechanism Research Project.
03:18 I've used his published gear schematics, and dimensions, together with the raw scan data to generate what I think is a faithful CAD model of the mechanism.
04:04 So while I will cast the raw stock for some of the parts from a homemade bronze, for convenience I'll make the majority of the device from commercially available brass stock.
04:32 These elements will be reflected in the reproduction, but the wood case presents a small problem with regard to this video series. It would obstruct a lot of the mechanism, and prevent you from seeing everything as its being built, and we can't have that.
05:00 At the end of the project, I can either remove the pillars entirely, and replace them with the original wooden structure.
