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.

A Pair of Dutch World War II Shipwrecks Have Disappeared Off the Coast of Malaysia

For nearly 80 years, two Dutch submarines have been occupying the ocean floor off the coast of Malaysia, with the remains of their crews still inside. They were among dozens of shipwrecks in the same area, all of them casualties of underwater World War II battles. Now, the ships— known as HNLMS O 16 and HNLMS K VII—are gone.

There’s nothing paranormal at work, though. Instead, the ships have vanished as a result of greed. Scavengers in the area have made a profitable pursuit of placing explosives within the wrecks, blowing them into manageable pieces and taking off with the scrap metal using a crane. Copper and bronze materials can also be resold. It’s estimated that about 40 ships in Indonesia, Singapore, and Malaysia have been demolished as a result of such efforts in recent years.

Because the ships are typically considered unmarked graves, the thieves may be committing the crime of desecrating corpses. After several British ships were found ransacked, the UK’s Ministry of Defense urged Indonesia to increase their efforts to protect the ships. The United States has dispatched representatives in Indonesia to guard ships they believe have been targeted by the scavengers.

Marine archaeologists have expressed some puzzlement at the phenomenon, as the scrap can often take weeks to retrieve, is frequently corroded, and would seemingly be cost-prohibitive to steal considering the labor involved. It’s possible that the ships may be targeted for having low-background metals, which are free from radiation because they pre-date atomic bomb testing and can be used in delicate scientific instruments like Geiger counters. In China, scrap metal could bring in about $1.3 million per ship.

UNESCO says that there are no fewer than 3 million shipwrecks lost beneath the waves, with many of their locations just waiting to be discovered. But for tourism purposes, the most interesting shipwrecks are those we already know about—and can visit. These 10 shipwrecks have intriguing stories, and they’re all places where you can step foot, although in some cases a boat (and possibly scuba gear) may be necessary. Remember: Look, don’t touch, since removing artifacts can spoil the chance for valuable archeological research (and is often illegal).

1. Bessie White, Fire Island, New York

The 200-foot schooner Bessie White wrecked off the shore of this barrier island while laden with coal in 1919 or 1922 (historians aren't sure of the exact date). The crew escaped, but the 3-year-old ship ran aground. In October 2012, Superstorm Sandy revealed the battered remnants of what's believed to be the ship's hull, which had been carried to a spot near Skunk Hollow in the Otis Pike Fire Island High Dune Wilderness. The National Park Service sometimes leads hikes to the wreckage, whose location over time provides scientists with clues to how the landscape of Fire Island has changed.

2. MS World Discoverer, Solomon Islands

A cruise ship built in 1974 that once carried passengers to polar regions, MS World Discoverer ran aground in the Solomon Islands in 2000. No lives were lost—all the passengers escaped via ferry after an uncharted rock pierced the ship's hull. Today the wreckage is still a tourist attraction in Roderick Bay in the Nggela Islands, listing heavily against the shore.

3. Peter Iredale, Warrenton, Oregon

Now a haunting ruin along the Oregon coast, the Peter Iredale was once a four-masted steel barque sailing vessel owned by British shipping firm Iredale & Porter. In September 1906, the ship left Santa Cruz, Mexico, on its way to Portland, Oregon, where it was supposed to pick up wheat bound for the United Kingdom. But a heavy wind and strong current sent her on to the breakers and she ran aground at Clatsop Beach, with three of her masts snapping from the impact, according to the Oregon History Project. The wreckage became an immediate tourist attraction, and despite being buffeted by the wind and waves ever since, it remains so today. It’s now part of Fort Stevens State Park.

4. MV Panagiotis, Zakynthos Island, Greece

This shipwreck in the Ionian Islands gives its beach its nicknames: Navagio ("shipwreck") Beach and Smugglers Cove. Supposedly, the Panagiotis, which wrecked there in the early 1980s, was smuggling cigarettes and alcohol. The rusting hulk of the boat is far from the only thing to see, however; the beach also attracts visitors for its clear turquoise waters and pristine pale sand. It’s also one of the most popular spots for BASE jumping in the world. The cove can be accessed only by boat. Be careful taking selfies from the cliff, however: At least one tourist fell to their death that way.

5. SS Maheno, Fraser Island, Australia

Once an ocean liner that plied the Tasman Sea between New Zealand and Australia, the SS Maheno was also used as a hospital ship for the New Zealand navy during World War I. She was later sold to a Japanese ship-breaking company for scrap, but broke apart in a cyclone on the journey to Japan in 1935. Since washing ashore on Australia's Fraser Island, the ship has become a major tourist attraction, despite not being particularly safe.

6. SS Oregon, Long Island Sound, New York

Once the fastest liner on the Atlantic, the SS Oregon sunk in 1886 just 18 miles off New York after hitting an unidentified schooner, often thought to be the Charles R. Morse. After an unsuccessful attempt to plug the hole in the hull with canvas, the captain ordered the ship abandoned, even though there were only enough lifeboats for half the ship's 852 passengers. (Fortunately, another ship arrived to save the passengers, and there were no casualties.) Today the wreck is a popular dive site in Long Island Sound. Although the ship's hull and decks have disintegrated over the years, the engine and boilers remain, among other remnants.

7. Uluburun, Bodrum, Turkey

Granted, it's in a museum, but the Uluburun wreck, which sank off the coast of Turkey during the late Bronze Age, is one of the oldest ships ever found—it dates back 3,500 years. A local sponge diver found the wreck of the Uluburun off the southwestern coast of Turkey in the early 1980s. Archeologists then spent 11 years studying the ship, collecting 20 tons of artifacts, including the remains of fruits and nuts, pottery, jewelry, tools, and weapons. No one knows who built the ship or where it was headed, but judging by the amount of gold onboard, someone rich was involved. The remains of the ship and its cargo, as well as a life-sized replica, are kept at the Bodrum Museum of Underwater Archaeology.

8. MV Captayannis, River Clyde, Scotland

Once a Greek sugar-carrying ship, the MV Captayannis has become a de facto home for birds and other wildlife since sinking in Scotland's River Clyde in 1974 during a terrible storm. (The minor collision with a BP oil tanker also didn't help.) The shallow waters around the wreck make it relatively accessible, and the ship seems likely to stay where it is, since its precise ownership is something of a mystery.

9. La Famille Express, Turks And Caicos Islands

Built in 1952 in Poland, La Famille Express served a large part of its life in the Soviet Navy (where it was known as Fort Shevchenko), before being sold and re-christened with its new name in 1999. It wrecked under mysterious circumstances around 2004. It now lies in just a few feet of water, an attractive landmark for boaters in the Turks and Caicos.

10. Eduard Bohlen, Namibia

This wreck is unusual for being buried entirely in the sand—it's now stranded about a quarter mile away from shore. A 2272-ton cargo ship that wrecked off Namibia's Skeleton Coast in 1909 in thick fog, the ship has since drifted so far from the water it's now completely land-locked.

This list first ran in 2015 and was republished in 2019.
