The Enduring Mystery of the Antikythera Mechanism

In 1900, a team of sponge divers submerged themselves into the sea off the island of Antikythera between mainland Greece and Crete and emerged with a curious find. Exploring a Roman shipwreck, they brought up a bronze-and-wood object that defied description. It looked like a clock, but not quite; it resembled a gear or wheel, but held no hints that it was once attached to any mode of transport.

The Antikythera mechanism, as it came to be known, was largely ignored for the next half-century, as researchers were preoccupied with the other artifacts found in the shipwreck and lacked the tools to see through its corroded exterior. But in recent decades, the importance and capability of the Greek-born device thought to date to the 1st or 2nd century BCE has slowly been unspooling. Depending on how you define the term, it may be the world’s first computer.

Although investigation into the strange box began when it was first retrieved, it wasn’t until researchers began using radiographs to examine its inner workings that the true nature of the Antikythera mechanism was discovered. Inside, they found 30 bronze gears that was operated by a hand crank. About the size of a shoebox, it acted as an astronomical calendar, predicting the cycles of the solar system in the coming decades. Lunar months and eclipses could also be anticipated. Greek zodiac signs and Egyptian calendar dates appear on the front. By turning the dial to one of the 365 days on its face, the user could anticipate the exact position of the Sun and Moon.

While X-rays could provide some basic structural information to investigators, microfocus X-rays, originally developed to find tiny fractures in turbine blades, were also put to use, revealing faded inscriptions that haven’t been visible for thousands of years. Tiny letters 1.2 millimeters tall told users what they might see when operating it.

There’s still much left to learn about the Antikythera mechanism. No one is quite sure who made it or for what purpose, although it’s possible a school may have been the beneficiary of its results. It’s also possible the Antikythera mechanism was devised to tell fortunes, as it provided information about eclipses that were associated with good and bad omens.

The remains of the Antikythera mechanism are housed in the National Archaeological Museum in Athens, Greece, along with sculptures and other relics from the dive. With the site of the wreck still being scouted, it’s possible more answers about this strange, impeccably designed machine may still be lurking at the bottom of the sea.

Gold Artifacts Discovered in 19th-Century Shipwreck That Was the ‘Titanic of Its Time’

On June 14, 1838, the steamship Pulaski was sailing off the coast of North Carolina, headed for Baltimore, when one of its boilers exploded, killing numerous passengers and causing colossal damage to the ship. It sank in less than an hour, taking two-thirds of its passengers with it. In January 2018, divers finally found the wreckage, and their latest expedition has brought back numerous new treasures, according to The Charlotte Observer, including a gold pocket watch that stopped just a few minutes after the boiler reportedly blew up.

The Pulaski disaster, which the Observer refers to as “the Titanic of its time,” was notable not just for its high death toll, but for whom it was carrying when it went down. The luxury steamship’s wealthy passengers included former New York Congressman William Rochester and prominent Savannah banker and businessman Gazaway Bugg Lamar, then one of the richest men in the region. At the time, the North Carolina Standard called the sinking “the most painful catastrophe that has ever occurred upon the American coast.”

Divers from Blue Water Ventures International and Endurance Exploration Group (which owns the rights to the site) have located a number of artifacts that support the belief that the wreck they found is, in fact, what’s left of the Pulaski.

While they have yet to find the engraved ship’s bell (the main object used to authenticate a wreck), divers identified a few artifacts engraved with the name Pulaski, as well as numerous coins that were all produced prior to 1838. The 150 gold and silver coins discovered thus far are worth hundreds of thousands of dollars today. They’ve also discovered silverware, keys, thimbles, and the ship's anchor.

And in their most recent expedition, the divers found a unique gold watch that further supports the claim that this ship is the Pulaski. The hands of the engraved solid gold pocket watch on a gold chain—a piece only the wealthiest of men could afford—are stopped at 11:05, just five minutes after the boiler reportedly exploded.

The excavation of the remains of the ship will hopefully illuminate more of its story. Already, it has changed what we know about the ship’s final night: The wreck was discovered 40 miles off the North Carolina coast, a bit farther than the 30 miles estimated in initial newspaper reports of the disaster.

The investigators hope to eventually find evidence that will allow them to pinpoint why the deadly explosion occurred. While such explosions weren’t rare for steamships at the time, the crew may have pushed the ship beyond its limits in an attempt to reach its destination faster, causing the boiler to burst. Expeditions to the wreckage are ongoing.

$2.5 Million in World War II-Era Cash Discovered Beneath Winston Churchill's Former Tailor's Shop

A valuable secret has been hiding beneath the floorboards of a sporting goods store in the UK since World War II. As the BBC reports, about £30,000 in roughly 80-year-old British bank notes was unearthed by a renovation project at the Cotswold Outdoor store in Brighton. Adjusting for inflation, their value would be equal to roughly $2.5 million today.

Owner Russ Davis came across the hidden treasure while tearing out decades-worth of carpet and tiles beneath the property. What he initially assumed was a block of wood turned out to be a wad of cash caked in dirt. Each bundle held about £1000 worth of £1 and £5 notes, with about 30 bundles in total.

The bills are badly damaged, but one surviving design element holds an important clue to their history. Each note is printed in blue, the color of the emergency wartime currency first issued by the Bank of England in 1940.

At the time the money was buried, the property was home to the famous British furrier and couturier Bradley Gowns. Prime Minister Winston Churchill and his wife, Lady Clementine Churchill, were reportedly regular customers.

The reason the fortune was stowed beneath the building in the first place remains a mystery. Davis imagines that it might have come from a bank robbery, while Howard Bradley, heir to the Bradley Gowns family business, suspects it might have been stashed there as a getaway fund in anticipation of a Nazi invasion, as he told the New York Post.

The hoard will remain in the possession of the Sussex police as more details on the story emerge.
