These Huge Roman Mosaics Were Hidden Under City Streets For 1,700 Years 

Twenty years ago, construction workers in the Israeli town of Lod working under a city street came across something extraordinary: A massive mosaic, laid down almost two millennia before. Now, they’ve found another.

The Lod Mosaic has become iconic over the years: It was removed from the city street where it was found, it has traveled all over the world and has been displayed at the most important museums on Earth. It’s been the subject of volumes of academic study, spurring debates about what the perfectly-preserved Roman mosaic describes (some claim that it depicts a shipwreck that the wealthy person who commissioned it survived).

Lod, of course, is in Israel. But when this mosaic was made, it was a Roman colony, as the mosaic’s official website explains:

Lod is ancient Lydda, which was destroyed by the Romans in A.D. 66 during the Jewish War. Refounded by Hadrian as Diospolis, Lydda was awarded the rank of a Roman colony under Septimius Severus in A.D. 200. It remained in Roman hands until becoming a Christian city and eventually succumbing to Arab conquerors in A.D. 636… Debris covering the floors contained pottery and coins of the third and fourth centuries A.D., suggesting that the mosaics were laid in about A.D. 300.

The mosaic’s discovery in 1996 brought new attention to Lod, a downtrodden city that saw tens of thousands of new visitors, the New York Times reported in 2009. The city planned a visitor center dedicated to the ancient piece–and the process of building that structure has accidentally uncovered more treasures.

Today, the city and the Israel Antiquities Authority announced that during the construction process, workers uncovered—yep—another Roman mosaic, as well as other fragments and details of the upper-class home where the original mosaic was discovered in 1996:

The new, 42-foot-long mosaic was situated in a covered courtyard, and it depicts the kinds of pastoral scenes you’d expect of a well-bred Roman of the time: There are vases, fish, birds, and scenes like a lion-esque animal is tearing into its prey.

Officials today described this multi-mosaic house as “meticulous and luxurious,” a space that would have been *raises pinky finger* “in the best tradition of the well-born of the period.” Now, the museum will be redesigned to include the second mosaic—and it seems pretty likely that these fragments will continue to be discovered.

It’s actually not that unusual for mosaics from the Roman or Byzantine era to be uncovered by modern construction, either in Israel or elsewhere. We’ve seen a rash of mosaics uncovered over the past few decades, as city streets and infrastructure are updated and as construction of new neighborhoods goes forward.

Mosaics are also extraordinarily durable: Not only are they solid and made from stone—they’re flat, which means they won’t collapse or crumble like actual three-dimensional structures and artifacts. In a way, they are the time capsule: Resistant to water and weather, and almost unbreakable.

Almost.

The first Lod Mosaic, for example, has a hole where a cesspit was dug into the ground a few hundred years later. It just goes to show: if you really want to understand a city, from its sewage to its greatest artifacts, look beneath its streets.

What WWII’s Top Secret Spy Manual Can Teach You About Wilderness Survival

What WWII's Top Secret Spy Manual Can Teach You About Wilderness Survival

Before there was a CIA or an MI6 there was the Special Operations Executive. And, as WWII heated up, it put all of its collective tradecraft knowledge into a single training manual. And, it turns out that training spies to operate behind enemy lines is often good training for going outdoors, too.

The abridged history of this manual is that, as America’s participation in WWII became more and more inevitable, the British and American militaries identified the need to train a corps of spies who could operate behind enemy lines, leading groups of partisans, or conducting their own intelligence gathering or sabotage. Spying, as it’s understood in the modern context, was a very limited profession at the time, so a method had to be found to impart the knowledge of a few to many students, across multiple training camps. That was achieved in part by enlisting specialists to train students in specific skills, and these camps had incredibly high instructor-to-student ratios as a result. But, the basic program and its knowledge base also had to be written down. So, the SOE did just that, creating its own training syllabus.

The best surviving copy of that syllabus happens to be the one used at Special Training School 103, or “Camp X” which opened to train American spies two days before Japan bombed Pearl Harbor. It now resides in the United Kingdom’s National Archives in Kew, a suburb of London. Quotes from it are used in this article.

The pre-war approach of Camp X scaled quickly as America went to war. While only 760 Americans ever received the training detailed in this manual, it formed the basis for the training program implemented by America’s new Central Intelligence Agency when that was formed the next year.

That original manual was unearthed by Denis Rigden, and is re-printed in its entirety in his book, “How To Be A Spy.”

What makes it particularly interesting to us outdoors types is that this knowledge is drawn from a time before modern technology invaded the battlefield. A time before exploding cigars or microfilm cameras or night vision goggles. Its shared knowledge is what proved successful in the field, during wartime and its presentation here is ruthlessly efficient. It’s not politically correct or the kind of advice that’s been run past lawyer’s to absolve its authors of liability. It’s what enabled early spies to parachute into enemy held territory, blow shit up, then make their escape.

Let’s go through the manual, pull out the knowledge that’s applicable to us hikers, sportsmen and nature lovers and discuss how it’s still relevant to us in the modern world.

Observation

What WWII's Top Secret Spy Manual Can Teach You About Wilderness Survival

This is as true of climbing, hunting or simply crossing challenging terrain or dealing with a dangerous situation as it is plotting enemy movements. The syllabus also emphasizes the importance of ensuring your information is up to date. A detailed assessment achieved the day before is invaluable for forward planning, but take some time to ensure that what you saw before remains the case before you move.

Camouflage

What WWII's Top Secret Spy Manual Can Teach You About Wilderness Survival

Not just for hunters. Anyone who wants to observe wildlife or who may need to ascertain the motives of a strange group of people in the middle of nowhere can benefit from these general practices. And, the syllabus emphasizes that you can quickly adopt the principles of camouflage on the fly by using terrain or brush to mask your silhouette. It also identifies motion as the thing that will give you away. Simply remaining still will prevent people or animals from detecting you nine times out of ten.

What WWII's Top Secret Spy Manual Can Teach You About Wilderness Survival

Understand the different kinds of camouflage, as defined by the syllabus, is key to successfully hiding from observation. This is a great example of how these different types can be used together, enabling you to totally disappear into your environment while remaining ready to act.

What WWII's Top Secret Spy Manual Can Teach You About Wilderness Survival

Light, shadows and movement are how effective camouflage works. Actual color matching is far less important.

After those are achieved, worry about making your outline with disruptive patterns, eliminate your shadow by pressing yourself closely to the ground or an object, then consider the overall tone of your background and attempt to match it.

What WWII's Top Secret Spy Manual Can Teach You About Wilderness Survival

The syllabus goes onto recommend you cover yourself in natural vegetation to achieve the above goals, but cautions against using this method in hot sun as the plucked branches and whatnot will quickly wither and become, “worse than useless.”

Using natural features, vegetation or manmade materials to mask your silhouette is an easy, immediate way to disguise yourself.

Optics

And aside from clothing, here’s their packing list. Don’t need much more than that!

Reading Sign

The syllabus going into the importance of reading animal movements at length. I’ll spare you the couple hundred words by simply saying: become familiar with the behavior of birds and other small animals in your area, they’re frequently a dead giveaway to the presence of humans or large predators.

Staying Hidden At Night

This is great advice. Basic earth tones always work best: grey and brown. And sound control becomes even more important, for reasons you’ll read below.

I didn’t know that! I’m going to go pull out all my binoculars and see which ones should work, then give it a try.

Crossing A River

What WWII's Top Secret Spy Manual Can Teach You About Wilderness Survival

What WWII's Top Secret Spy Manual Can Teach You About Wilderness Survival

Crossing moving water is dangerous. But probably less dangerous than jumping between wet rocks. The potential for a fall injuring you or knocking you unconscious, then dumping you into moving water, just has very serious ramifications. Any river crossings need to be calculated, planned and conducted with extreme care.

First Aid

The priority in any first aid situation is to first assess the person’s airway, breathing, and circulation. Understandably, the syllabus deals mostly with injuries causing blood loss.

What WWII's Top Secret Spy Manual Can Teach You About Wilderness Survival

Tourniquets are a controversial first aid technique and should not be attempted without training.

Self Defense

What WWII's Top Secret Spy Manual Can Teach You About Wilderness Survival

The syllabus goes into much more detail, but it’s largely oriented around killing, so we won’t reprint that here.

How Can The SOE Syllabus Help You?

A lot of this stuff, like the camouflage or silent movement techniques, may at first seen overwhelming. The title of this paper is a giveaway though. As a syllabus, it’s an overview of training, not the complete package. The concepts and techniques identified would have been taught and practiced in classes. And you can do pretty much the same thing, applying what you read about here to your next outdoors adventures.

A nighttime dog walk, for instance, is a great time to practice your night vision techniques. A hike is a great time to practice silent moving. Basic camouflage can be applied any time you’re outside, simply by dressing in earth tones and using natural features to disguise your silhouette. Work up to it, then find a deer or other wary animal and try to sneak up on it. I bet you’ll be surprised at not only how achievable that can be, but how effective all this stuff combined is at improving your experience outside. Minimizing your presence outdoors is the best way to observe nature.

Use Lag Bolts to Extend the Life of Your Outdoor Deck 

Wood decks and stairs are susceptible to rot and water damage. Use lag bolts to raise deck posts and stair risers above footings to prevent water from seeping into the wood.

Use your impact driver to drive 2 1/2” lag bolts into the base of your wood project and leave about 3/4” of an inch of space between the head of the bolt and the wood. This space will keep the wood from soaking up water and also provide an easy way to fine-tune the level of the posts by screwing the lag bolts in or out.

Another way to protect your wood from moisture is to wrap the ends with Blueskin membrane. This self-adhering waterproof membrane provides another layer of protection for your wood which will make it last longer.

Combining these two moisture prevention tips can help extend the life of your deck by years.

The Latest Trend Among Biohackers Is Implanting LED Lights Beneath Your Skin

The Latest Trend Among Biohackers Is Implanting LED Lights Beneath Your Skin

Inspired by bioluminescent organisms, the DIY biohackers at Grindhouse Wetware have unveiled their latest creation—a magnetically activated, LED-equipped silicone implant.

As Motherboard reports, the Pittsburgh-based biohacking collective performed three implantations in conjunction with a simultaneous operation in Dusseldorf last Saturday. The new light-up device, dubbed the Northstar V1, is about the size of a large coin, making it considerably smaller than an earlier version, the Circadia 1.0 computer chip. The procedure to implant the device required only 15 minutes (gory pictures here), and was performed under strict conditions.

Once implanted and activated, the Northstar device can backlight existing tattoos or mimic bioluminescence. When a magnet is placed on the device, its five LED lights start to blink. After ten seconds, it goes back into sleep mode. The Grindhouse guys think it’ll light up about 10,000 times before the batteries die out and can no longer be recharged. Once this happens the device will have to be surgically removed. (Photo credit: Grindhouse Wetware/Ryan O’Shea)

When Motherboard’s Anna Neifer asked why his team developed the device, Grindhouse Wetware cofounder Tim Cannon said: “You know, people from the biohacking community wanted it. They contacted us because they wanted to light up their tattoos. That’s how we generate our implants, we let the community inspire us.”

The group plans on making the device available next year. Ideally, Grindhouse would like to sell as many as 100 Northstar V1 devices through tattoo studios worldwide.

Looking to the future, Grindhouse has big plans. A future version of the chip could, in addition to its cosmetic functionality, deliver important biometric information to an external device like a phone. Another neat feature will be the ability of the chip to register a person’s hand movements, and wirelessly relay those signals to receiving device. It would serve as a customizable hands-free controller. You’ll never have to say, “Hey Siri” again.

There’s much more at Motherboard.
