Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "The Antikythera Mechanism." An orrery is a mechanical model of the Solar System that illustrates or predicts the relative positions and motions of planets and their associated moons. The Antikythera Mechanism (shown) is an ancient Greek hand-powered orrery that was used to predict astronomical positions and eclipses decades in advance. It was among wreckage retrieved from a shipwreck off the coast of the Greek island Antikythera in 1901.
The instrument is believed to have been designed and constructed by Greek scientists and has been variously dated to 205 to 87 BC. The knowledge of this technology is lost in antiquity. Clockwork later appeared in medieval Byzantine and Islamic periods, but works with similar complexity did not appear again until the 14th century with the development of mechanical astronomical clocks in Europe. One could accurately describe the Antikythera Mechanism as the oldest example of an analog (versus today's digital) computer.

Good morning Maj William W. 'Bill' Price and thank you for this interesting technological piece of the equipment used to predict the motion of celestial objects in the skies above created during the period between 205 to 87 BC. Crude by today's standards, but a tremendous scientific asset in those days... There is always something fascinating in the world of Astronomy, Bill... Have a great Sunday my friend...
As an adjunct to your amazing APOD on this subject of The Antikythera Mechanism" I submit this video as a fundamental part of the history of the device... I hope your followers enjoy this first of several videos on this subject.

Thank you my friend Maj William W. 'Bill' Price for posting the NASA Astronomy Picture of the Day (APOD) for Sunday, March 21, 2021 entitled "The Antikythera Mechanism."

APOD Background
"Explanation: No one knew that 2,000 years ago, the technology existed to build such a device. The Antikythera mechanism, pictured, is now widely regarded as the first computer. Found at the bottom of the sea aboard a decaying Greek ship, its complexity prompted decades of study, and even today some of its functions likely remain unknown. X-ray images of the device, however, have confirmed that a main function of its numerous clock-like wheels and gears is to create a portable, hand-cranked, Earth-centered, orrery of the sky, predicting future star and planet locations as well as lunar and solar eclipses. The corroded core of the Antikythera mechanism's largest gear is featured, spanning about 13 centimeters, while the entire mechanism was 33 centimeters high, making it similar in size to a large book. Recently, modern computer modeling of missing components is allowing for the creation of a more complete replica of this surprising ancient machine.
Thank you my friend Sgt (Join to see) for mentioning me.
Antikythera ASP05 Video 2: Walking Blues
The various members of the Antikythera Survey Project begin to experience the Walkin' Blues during the 2005 archaeological survey of the Greek Island of Antikythera.
Battling injuries and the maquis, they persevere through another day of fieldwalking and earn their well-deserved rest.
