Plumbata are substantial war darts that have their origins in Ancient Greece and were favoured by late Empire Romans. They have rather nasty barbed head, a lead weight for inertia and were thrown as fighting lines started to close. Their nickname amongst the Romans was Little barbs of Mars
. Nasty as they look, how do you throw them and what do they do when they get there? — via Youtube
The Roadmachines Mono-Rail may have been the only truly useful, fit-for-purpose monorail in the world. Of the hundreds that were built, most were never meant for passengers. But they did carry a couple of famous people in their time, including a certain secret agent…
Thank you to the staff and volunteers at the Amberley Museum — Harry and Gerry in particular — for running the monorail specially, and letting me film! The Amberley Museum is a massive industrial heritage museum in the South Downs, and you can find out more about them here — via Youtube
A secret cabal is taking over the world. They kidnap children, slaughter, and eat them to gain power from their blood. They control high positions in government, banks, international finance, the news media, and the church. They want to disarm the police. They promote homosexuality and pedophilia. They plan to mongrelize the white race so it will lose its essential power.
Does this conspiracy theory sound familiar? It is. The same narrative has been repackaged by QAnon.
I have studied and worked to prevent genocide for forty years. Genocide Watch and the Alliance Against Genocide, the first international anti-genocide coalition, see such hate-filled conspiracy theories as early warning signs of deadly genocidal violence.
The plot, described above, was the conspiracy revealed
in the most influential anti-Jewish pamphlet of all time. It was called The Protocols of the Elders of Zion. It was written by Russian anti-Jewish propagandists around 1902. It collected myths about a Jewish plot to take over the world that had existed for hundreds of years — via Just Security
Antikythera Fragment #8 – Layout Line Visibility
Wine, wax, woad and yes, There Will Be Blood… all in an effort to discover the best ancient marking fluid. And Clickspring’ll let you decide how the blood supply issue might have been dealt with in the ancient shop – he’s guessing it might not have been much fun being the apprentice on the day the large dial was marked out — via Youtube
Gli is a cross-eyed adorable cat that has been living in Hagia Sophia for the past 15 years. The Hagia Sophia is more than 2,000 years old and is one of the most extraordinary structures ever built. It has been a temple, church, mosque and museum through its long history.

Antikythera Mechanism Episode 9 – Making The Epicyclic Pin and Slot Gearing
In this video Clickspring makes what is arguably the most impressive section of the mechanism — the small pin-and-slot module that models the Ancient Greek theory of the variable motion of the #dearMoon — via Youtube
Antikythera Mechanism Episode 8 – Making The Mean Lunar Sidereal Train
In this video Clickspring makes the gearing that calculates the mean sidereal period of the #dearMoon, and has a closer look at some of the mechanical limitations of the device — via Youtube

Antikythera Fragment #7 – Precision Soft Soldering
Continuing on with the investigation of what it was like inside the ancient workshop, here’s a closer look at another of the demonstrated techniques: The precise joining of metal using soft solder — via Youtube
The Antikythera Mechanism Episode 7 – Making The Saros & Exeligmos Train
In this video Clickspring makes the gearing that drives the eclipse prediction function of the mechanism. Be sure to check out the reference links below for more info on the Saros cycle, and other eclipse related stuff.
[EDIT: At 2:57 there is a typo – the final number in the denominator of the upper expression should be a 30 as per the sketch rather than 90 – Cheers 🙂 ] — via YoutubeAntikythera Fragment #6 – Making A Hand Powered Drill
The precision of the holes in the Antikythera mechanism is one of the most fascinating aspects of its construction. In this video Clickspring makes a tool that is capable of creating holes to the required standard, yet is consistent with the level of technology known to have existed in the period — via Youtube
Antikythera Fragment #5 – The First Precision Drill Bit
There are a number of cutting tools implied in the wreckage of the Antikythera Mechanism, and one of the most interesting is the drill bit. In this video Clickspring explores a possible method of how an effective and precise drill bit could have been made in antiquity — via Youtube
Antikythera Fragment #4 – Ancient Tool Technology – The First Hardened Steel
One of the key tool technologies that needs to be explored around the Antikythera mechanism is the simple hand held file. So this is the second of two Fragment videos relating to the making and hardening of a set of custom files, using materials and processes consistent with the period — via Youtube
The Antikythera Mechanism Episode 6 – Making The Metonic Calendar Train
In this video, the gearing that drives the Metonic, Callippic and Olympiad pointers is made. Clickspring recommends an article on the Athenian calendars for further detail on the ancient Greek approach to calendars — via Youtube

In this video the small assembly that enables the user to drive the mechanism in made — via Youtube
The Antikythera Mechanism Episode 4 – Making And Fitting B2
In this video the most recognisable component of the mechanism continues to take shape, and becomes the first moving part within the plates — via Youtube
Antikythera Fragment #3 – Ancient Tool Technology – Hand Cut Precision Files
There are quite a few very interesting tools still to come in this Fragment series, but Clickspring has to admit he has been super excited about these: A set of hand cut files suitable for constructing the Antikythera Mechanism — via Youtube
Antikythera Fragment #2 – Ancient Tool Technology – The Original Dividing Plate?
One thing about this machine that is truly surprising, is just how small the teeth are.
There’s a well established theory as to how the tooth divisions were marked out, but employing that process to mark out multiple wheels has forced Clickspring to question whether it can reasonably be applied to the Antikythera Mechanism.
So in this video Clickspring proposes an alternative process of wheel division, using only the non precision tools of the period — via Youtube
