The technical. Technological. Advancement. Is rapid, so. Rapid it's almost impossible, to keep up in the space of a lifetime. Rancic. We've discovered, thousands, of new sites from a range of different periods. Duncan. View the, data allows us to sharpen the focus of our inquiry and pinpoint, exactly where. To perform the dig. In. Archeology. State-of-the-art, technology, sometimes, assumes, the guise of an antiquated, handcart. While. Archaeologists. Root poising, and Roseanne shot set up their equipment on a meadow their. Colleagues, nearby, are preparing, a device that does look more high-tech. The. Geomagnetic, apparatus. Is so heavy it has to be towed by a vehicle both. Devices do the same thing only this one is larger and can survey a wider area. A, group. Of German and Irish archaeologists. Have met up at the old church at screen, a 15th. Century sites, steeped, in mysticism. But, the church ruin, is almost, young compared, to the ancient, monuments that, dot the surrounding, area. Northwest. Of Dublin the hill of screen is located, opposite, islands, cultural treasure, the, hill of tara a millennia. Old place, of assembly. The. Region, is also home to giant, megalithic, tombs, unique. Monuments, built around 3000. BCE, by. People who left nothing behind but their graves. A digital. Reconstruction lends. An impression, of the graves interiors. Many, built in alignment with astronomical. Events. The. Archaeologists, dragged the sensors across the meadow to determine, what lies beneath the surface. This. Device is 2 meters wide and equipped, with five sensors, you. Can cover two to three Hector's a day with the device like this so. It's a fast way of collecting, and evaluating. Archaeological. Data. Equipped. With 16 sensors, their colleagues magnetometer. Is even more effective, in gathering archaeological. Evidence. So. We need to be careful here because if, we swap the cables then the sensors will transmit the wrong positions. That's. Why we do a final check to see that everything's working so, the proof of the status will tell you the. Team is scouting for traces, of ancient life underground. Without, the intervention of, a shovel it's, a non-invasive technique. Called prospection. Are. Now hooking up the geomagnetic, device, to the computer the. Computer. Has the task of recording all the measurement data and showing, us where we have to prospect, even, when we are driving across the terrain, Invictus, hang forward to prospect in half. The, 16 sensor, device is used to take geomagnetic. Measurements. Of the ground. Really. Wondering what we were finding mysterious. The. Landscape, harbors, a history, that began thousands. Of years ago the. Archaeologists. Job description calls for knowledge not, just of history, but technology, too and today. It helps if they don't mind being followed by curious, horses, we, don't know exactly what, year the church was founded and we. Also want to know a little more about the history prior. To the earliest. Documentary. Sources, because. We have some, references, say from the the eighth century in the 10th century referring. To the. Hill, of screen being a place of burial. That's. Called the crosshair show us our exact position. With. The help of GPS data the archaeologists. Can steer their vehicle, across the meadow with the precision, they need to generate a comprehensive. Ground image. The. Sensors, dragging, behind their vehicle measure the Earth's magnetic. Field which, lies underground. Like an invisible veil, the. Presence of walls or graves alters, the pattern of magnetism, in the soil and, that. Is exactly what, the sensors can measure the. Computer, registers these, disturbances, to reveal a long-forgotten, structure. A shadow, of the past. 1,700. Kilometers, further east in Berlin, work, is underway on a different, type of digital archaeology in, game developer, Thomas Bremer's studio for virtual reality. It. Looks like a game but. It isn't. The. Game designers, are working with Berlin archaeologist. Kai kuhlmeier, hip. Technology, meets ancient, history their, cooperation, has yielded some surprising.
Discoveries For. Example, the Hittites, had an unusual. Reading, technique. This. One from left to right this, one from right to left this one from left to right this. Again, from right to left then, back again yeah. Like in wavy lines that's, awesome. Archaeologists. Are anchored, in past centuries and, that applies to their methodology, to. The. Rapid development of computer technology in general but, also a virtual archaeology. Is still something we need to get our heads around. And. When I tell people I'm working with a game designer they, just shut down because. Gaming, technology, sounds so frivolous, but. In fact this. Work is just the opposite. This, looks like a video game but. In fact it's a highly accurate copy, of a real temple, it's. The temple of the weather god from Aleppo one of the most important, deities, in the ancient Middle East the. Oldest parts of the temple date from the 3rd millennium BCE. With. Visualization, software, the operator, can make the Sun rise and set, allowing. For a view of the complex, in changing, daylight the. Viewer gets a sense of space size, and proportion. Providing, this damage though, we are not really standing, in this temple we can judge and see things very differently than, we could on a normal computer monitor. Morning. - am I on counter yeah. Just. The fact that I can stand here and for example squat. Down and, actually get a three-dimensional. View of the object that's, something I can't do on a normal computer monitor, at all. Aleppo. In Syria the. Temple was located in, the heart of the city in the medieval, Citadel from. 2012, rebels, holed up inside used, the Citadel to fire on government, troops the. Result, 5000, years of history turned, to dust in a brutal civil war in. Early 2011 the temple, was still intact. Hi Col Meyers team from Berlin was on site to scan the complex, security. In the country still seemed so stable that the professor, didn't just bring along his students, he, also took his young daughter on the trip. Below. Amelia you'll see another representation, of the weather god mounting, his chariot, here. He's presented his combat ready, what's. This, that's. The symbol for God and that's, a mace. Initially. It was solely research, but. The data required, new significance, through the ravages of the Syrian civil war. We. Had an unimaginably. Large amount of data but, when the Civil War erupted and we couldn't get there anymore we were left wondering what, do we do now. It, sounds almost cynical, now but, we were in an ideal position we. Were the only team, of Near Eastern, archaeologists. To have scanned everything, in 3d. It. Was a turn of good fortune in the midst of terrible misfortunes. It's younggook. The. Temple was badly damaged, in the war but. At least its memory, has been digitally, preserved. The. Scan data is so precise, the, inscriptions. Are even more legible, in virtual, reality than. They were in real life. That's. He be, hobbin on top when I learned to dig I had a piece of paper and a pencil that's mom that was all. Today. We can use a scanner, that is much more accurate than any reproduction, on the sheet of paper, of.
Course That also gives rise to new fields, of inquiry, and. We can see you know the olive harvest at home this is car. The. Generation, of exact copies, is a field that also interests, maritime, archaeologists. All over the world, measuring. And marking shipwrecks. Underwater, is one of their most demanding. And arduous, tasks, and the. Conditions, are not always as, good as they are here in the Baltic Sea of the German island of rügen. Only. Exceptional. Shipwrecks, are salvaged, and restored, like, the 14th, century Bremen. COG one, of the world's largest ship, finds. It. Took 18 years, of expensive, conservation. Work to restore it to its full glory, to. Learn more about this merchant, ship from 1380. Archeologists, created, a digital model of the kaga. The. Construction, of a ship like this is quite special everything. In the vessel is interconnected, if, you move one part by just 2 centimeters, it distorts, the entire shape of the ship so. The computer, gives you an overview. You're. Not dealing with a 23. Meter long ship you. Don't have to search the entire vessel. For the place responsible. For a deformation. Instead. You can clearly see how every step you take impacts, the entire structure, and check whether a given step has changed the overall shape. The. Technology allowed, researchers for, example to. Find out how the COG was sailed without, ever having to lower it into water. There. Is a shipwreck, off rügen that is not worth recovering, but, it is nevertheless of, interest to archeologists. Thus. What's. Special about this find is that it dates from the middle or perhaps even the early 16th, century a period, from which very few ships, have been found and there's. Evidence that the word may have come from handbook d, bizarre codes, are or sandbox, dams oil. Even. Today certain. Details of the ship can be more clearly rendered, if they are copied underwater, by hand. But. The main job is done by a special, camera it. Takes hundreds. Of images that are then used to generate a 3d, computer model, of the shipwreck, while. The wood has been perfectly, preserved in the nutrient-poor, water off the Baltic the, current has eroded the rig down to its floor. Deb. It's Tobias that's the great thing about it is you never see the wreck like this on a dive because visibility. Is poor but. You can create a model like this even, if you have a visibility, of just 30 centimeters, you. Just have to take enough photo so they overlap, then. You're looking at something no one has ever seen in that shape or form. For, example, the frigates ballast, stones that still lie along the ship floor, without. Them the vessel couldn't have carried its cargo of heavy cannons. One. Of the most spectacular exhibits. In the collection, of Berlin's Museum of Islamic art, goes, largely unnoticed, by, visitors, but. The digital world is coming to its rescue. Kai, Col Myers latest, project, is the richly carved wood dome that was originally, housed in the nasstrac, palaces, of the world-famous, Alhambra. In Granada Spain. In. Berlin, the dome is forced, to lead a wallflower, existence, for, conservation, reasons. The. Dome is very poorly illuminated here, in Berlin. Visitors. Can't appreciate it the way they could omit the light conditions in the Alhambra. Our. Aim is to recreate, those lighting conditions, virtually, to, allow visitors both here in the Berlin museum and, visitors, to the Alhambra an experience, of the dome in its original context. In. Invasion, context such as Italy. In, 1891. The, banker our turf on Grenaa was granted, permission by the spanish authorities to, move the dome to germany he. Had acquired a small palace on the alhambra, from a Spanish opera singer and later, bequeathed, it to the Spanish state but, he decided to keep the dome for himself, for. A time it, decorated. His villa in Berlin, before he donated it to the museum. The. Dome was originally, painted and gilded, it's. Crafted, from cedar and poplar wood and consists. Of dozens, of parts a, star. Ornament, of heavenly, beauty. One. Of the world's most important. Prehistoric. Landscapes, is located, in a bend of Islands River Boyne northwest, of Dublin. The. Passage graves of Newgrange Daffy and Nath were designated a, UNESCO World, Heritage Site in, 1993. The. Central Neolithic mound of mouth has a circumference. Of 275. Metres, and is, surrounded by 20 smaller tombs. The, significance, of numerous, engraved, stones remains, a mystery, many, stories, and legends, are associated. With the enormous, mounds, they, are said to be the birthplace of heroes, the. Hidden dwellings of, elves, and kings. The. Mound graves of Newgrange darth and mouth are all, located, within sight of each other. It's. Long been standard, practice in archaeology, to use drones to get an overview of the landscape. The. Drones gather data to build digital terrain models, on the computer, sites.
With Churches, dating, from the Middle Ages often. Have an older, heritage invisible. Underground. Evil. Rulers seeking to exert political military. Or religious, controller, for a territory, would occupy any place that carried, a particular, significance, so. We use these old sites as a starting, point because. It's easy to imagine that with Christianization. These ancient, sites were chosen as, places, to build churches. And. In. Fact when it comes time to evaluate the data from their geomagnetic, survey, the, archaeologists. Discover, round structures. That appear to predate. The small medieval, village. They. May be traces of circular, graves enclosing, burial mounds or they could be round house. In. Their distribution these objects, make no reference to this ditch complex, so, one can assume that they date from another, period. Discovering. Hidden relics, without digging draws, on technology, that originated. In military, applications. Which, Tim Takeo physically, from a certain geophysical, methods are based on measuring, differences, in the Earth's magnetic, field, the. Technology, comes from hunting submarines. Which, could be located under water because they created disturbances. In the Earth's magnetic field. This. Is a method that we now use in, a modified, form in archeology, Watson. Axel. Paz Lucien E is surrounded. By traces, of the past, his, work focuses on the mountain plateau of globert near Frankfurt that, was first settled thousands. Of years ago the. Celts in particular left, their mark on the area today. It is known that the plateau was surrounded, by a magnificent. Wall it, did not serve as a fortification, the. Slope was steep enough rather. It was designed to signal the power and splendor, of the Celtic princes. It. Began here in the so-called Neolithic, Age with the emergence of the first farmers, and cattle breeders, in the region of the Vetta the, first settlement, up here the Mitchells burg culture had no ramparts. Development. Continued. Into the late bronze age and by the early Iron Age around 500. BCE it. Was settled by the first people, we could classify as Celts and, they were also the first to fortify. This plateau, stitched. On an. Inconspicuous. Aerial. Photo taken, in 1988. Opened. The door to one of the most spectacular discoveries. In archaeology, in Germany. Archaeologists. Have been using aerial, photography, for decades, to identify, structures in the ground but, this method only yields, results following long periods, of drought. Ones. Each here. In. The field here you can see a darker, structure relatively, clearly in the grain which. Indicates that the grain is being supplied with more moisture, in this particular, place. So. It can be assumed that there is a ditch there that retains, the moisture better, there's, a holding.
The, Grave of a Celtic Prince was discovered, deep in the field at the foot of the globe urgh the. Corresponding, burial, mound had been plowed away long ago the. Huge hill has since been reconstructed and, a, museum installed, behind the hill. A. Life-sized. Sandstone. Figure was found near the grave. The. Figure was endowed with decorative, chains and rings it, was lying in a ditch together. With fragments, from other statues, the. Celtic Prince is crowned, by a strange, headpiece, a. Golden. Chain was found in the princes grave, the. Stone figure was depicted, wearing exactly, the same chain. It's. Likely, that the stone warrior prince of glaub egg is the exact, likeness of a person who lived more than two-and-a-half thousand. Years ago. The. Body in the tomb was found with the same strange, headpiece, as the one crowning, the stone figure. In. Subsequent, years aerial, archaeology, has made further strides. We. Are leaving the cluster in addition to classical, aerial, archaeology now carried out digitally, we, also have other computer. Assisted, methods of non-destructive, testing, to obtain information about archaeological. Remains. And. Often saw become, the. Most important, of these methods, is the lidar scan. The. Scanner is fitted to an airplane and surveys the landscape, below, lidar. Scanning, was originally, used by surveyors, but. For archaeologists, the data has proved a quantum, leap in knowledge even. If lidar terrain, models look somewhat, unspectacular, at, first glance. What. Makes the lidar scan, so invaluable is the methods ability, to remove the noise of trees and vegetation from, the data. Levin, knows diluted ground-penetrating. Radar. Shoots, electromagnetic. Pulses into the earth from airplanes, and sometimes helicopters. These. Signals, are reflected, back by any underground, structures, and the, difference in the laser return, times makes, it possible to create a 3d, image of the terrain it. Works in the forest as well because, enough laser light can penetrate through, the trees so, that we achieve a relatively, exact surface, image even in the forest, on. This image you can follow the course of the Roman Lemus the. Border between the Roman Empire and non. Occupied, regions. This. Here, may. Have been a watchtower. And. Here in the forest the, remnants, of a field of burial, mounds this. One here could theoretically, be a burial, mound that was opened in the past my, guess would be sometime, in the 18th century, at. The time people typically, entered, from the top we call it funneling, so, they've dug a funnel, into the mound to extract burial, objects or skeletons, and what, remained, were these small, holes at the top of the mound these. Faint traces indicate that's, what happened here. Axial, pasa Lucian he discovered, a large burial, mound very close to the grave of the Celtic Prince a tiny. Dot on the scanner image not, visible, as a grave amid the thicket of the forest. Multiple. Layers of our pasts lie beneath the ground we walk on we. Just can't see it. Digital. Archaeology makes. The invisible, visible. In, Ireland, to the number of discovered, monuments, has increased, a hundredfold, with, the use of modern prospecting. Methods, one. Particularly, spectacular. Example, is the Hill of Tara, the mysterious, national.
Treasure It. Was the seat of Irish, kings and pagan, priests, at the height of their power. The. Hill of Tara exudes. An air of magic, in Ireland. Back. In the 19th century Irishmen. Would gather here and, swear a holy oath not. To rest until, the land had won its independence. And. There was a reason they did it here. Today. Self-proclaimed. Druids inhabit, the area at night, you can hear them playing their harps. Christians. Built a church here. Ruth. Poising, and Roseann shot systematically. Stride the length and breadth of the meadow on the expansive. Plateau with their magnetometer. Here. In Terra it's a safe bet they'll, find something interesting and, they. Do the. Digital data shows, numerous circles. Below the surface grave. Mounds, or maybe sites of assembly. When. We first started investigating. Tired there were about twenty five monuments known these monument that are visible but, through geophysical, survey we know there's more than a hundred monuments. A lot of which you can't see above-ground are buried beneath the surface. Old. Maps, can give clues to vanish structures. The, people of Terah lived thousands. Of years before the invention of writing they. Recorded, their history, in the ground and crafted, sacred, landscapes, that, only need to be deciphered a. Deep. Channel on the plateau was probably once a processional, route it's. Clearly visible on the lidar scan, it. Leads directly to the inner sanctuary the, Ratner II a large, ring, wall complex, in, fact it's a processional, way and believe. This is the, route that the king, elect would take on his, way up to the summit of the hill of tara to be inaugurated. To. The left and right of the processional, route ramparts. Were built to direct the March as gaze to key monuments. Interestingly. There. Are a number of gaps, along, the length of the banks in which you, can get a view out on very, significant, monuments, and in, particular burrow amendments. So. It seems prehistoric. Builders knew, all about visual, effects. But, they also show infinite what I personally, find particularly, appealing is that up here you're afforded a wide view of the landscape surrounding. Town and. There are similar monuments, on many of these mountains, and hilltops. Not. In the abundance we find on the hill Otara that is truly unique but, there are also individual. Monuments, which ultimately may, have a common point of reference. The. Hill of Ward is another site that harbors, a mysterious. Sanctuary. Students. From Dublin are digging, their way into the hill at precisely, defined, points, according. To legend Halloween. Originated. On the hill of ward a pagan, festival, of fire on the night of October the 31st. And. In. Fact the students, do find a large amount, of animal, bones an indication. That people here may have come together for large celebrations, with, copious, amounts, of food, Irish. Archaeologist, Stephen Davis has surveyed the hill but, he was unable to find, anything with geomagnetic. He. Has a simple explanation. One. Of the problems with using magnetic survey, here which is what we might use of course the rest of it it's all this heavy burning, that you've seen behind you there's, all this heavy burning, it's, very heavily magnetic, just because it's been burned so, the. Whole thing really lights up and you can't see anything at all so with with earth resistance, in this case so we can see that this big mound behind us here is actually defined by us a stone wall, which, is actually what we're taking out now in this case that's why that's why we dug here we've, dug, a small section into the side of this mound with, the stone, ward in the centre, geo. Electric surveys, measure the soil resistance, and create images of structures, underground. Only. Now can researchers. Identify, the various, walls and ditches, in the complex. Were. Rituals, really celebrated. And large bonfires. Ignited. Here overnight on October, the 31st.
Archeological, Clues could, confirm, the theory. Is. The Lehrer Bernie. Okay. So the. Burn into a place before whatever happened here that's falling, down onto itself and this, extends, all the way up here, they. Have a fire festival here now but. It's it's. Hypothesized. Had, a fire festival going back almost since the I&A there. Are many. Evil references, to preachers. And druids meeting, here and lighting a great fire. But. Those references, would be several hundred years after it would have happened so we we always treat them with a certain skepticism but. We. Are finding a lot of evidence of fire here so who knows. Aside. From graves, and ritual sites, the people who built these complex has left only one thing behind the. Bodies of their murdered, kings, they're. Bog bodies are on display at the National, Museum of Ireland in Dublin the. Graves and their dead are the only testimony, of early Irish people are people, who had no written language. Like. In Tara a processional. Route can be made out in the digital data from the hill of ward a road. That is no longer visible in the meadows. The. Same was true of the Celtic burial, ground on the globe ERG. Here. It's not just the burial mound that's been reconstructed. But, also the processional, route leading up to the hill it. Was flanked, by deep trenches, and originally. Much longer, this. Is clear from the digital data a geomagnetic. Survey, has revealed the roads further course. Today. It's known that the road was bordered, by a high wall which. Was up to 12 meters wide at the base. Visitors. Could only see, the grave mound after turning, the corner. Researchers. Believe the hill was even whitewashed, like. In Ireland the structures, here were designed with visuals, in mind and. Astronomically. Aligned. Others. It's, not a road that marks, a path from A to B it's. Aligned, with the southern, major lunar standstill an astronomical. Phenomenon that. Occurs every 18.6, years so, it was possible to devise units of time without a calendar without a watch over a longer period of time, well, is your nest. The, Alhambra in, Granada, there. Are few other sites in Europe that draw as many tourists. Every. Day only, 5,000, visitors are allowed to enter the castle the, tickets are sold out weeks in advance. Keuchel. Maya feels privileged, to work here. Kuhlmeier, and his team have been working for days at the Palacio, del parral the. Villa that belonged to a sultan then, to an opera singer and then a German banker from Berlin it. Was from here that our tour Fond winner removed, the decorative dome in 1891. It. Was replaced, by a poor copy. It's. Really a great feeling to, be, able to get a sense of the domes original, setting. The. Aromas, the views through the windows all, make for an entirely different experience than, if you're standing in a museum and looking up in a dimly lit room. Every. Detail, of the chamber is carefully, documented, with a high performance scanner. Watching. The lengths being gone to hear one, can't help but ask why Berlin, doesn't just return the dome to its original home the. Archaeologists, call such considerations. A historical. Pickle, previously gone the. Dome was brought to Berlin legally there's no question about it, it, now has its own story and that story includes. That of its previous owner the German banker who acquired it and brought it to Germany. He. Incorporated. It into his own villa there and then via, a detour, it arrived at the Berlin Museum. This. Story belongs to the objects provenance, it can't be ignored. Let's. See me disappear. The, digital, reconstruction reveals. The Chamber's long-lost, splendor, the. Original, dome housed in the Berlin museum has. Been integrated, into this virtual reality, experience. The. Dome from this chamber was one of the oldest components, of the Alhambra, probably. Carved around 1320. If. The dome was still in place here the tower chamber is too small to accommodate the, alhambra z' 5000, daily visitors, no. One would ever get a glimpse of a Tina. In. Places, where the walls are too high for the scanner, another, method is used. Photogrammetry. A 3d. Model is generated, using thousands. Of overlapping, photos. In, principle. I think it's a good idea to upload, 3d images, of these objects, to the internet, because. Then everyone, can access them so, conch feeding. In. Island scientists. Are a step ahead, many. Scanned, objects, have already been posted on the Internet. Before. The German archaeologists. Returned home they, take a few soil samples, it's, an inexpensive, substitute. For an excavation. The. Researchers. Are in doubt an area, dotted, with prehistoric, burial mounds, and medieval farms.
A Power. Cable runs underground, through a small medieval settlement. Geomagnetic. Data, helps, archaeologists, avoid hitting an electric, cable rather, than, a medieval, ditch. That's. The big difference today in the ideal scenario I already know a tremendous amount about the site before I start, my dig and, that enables, me to plan the dig very precisely. Generally. The areas of excavation, are much smaller than they used to be because, I simply don't have to search as much as I used to. The. Archaeologists. Are drilling at a location they suspect, harbors a waste pit like. Modern, garbage bins their historical, predecessors say. A lot about the living conditions, of the people who lived here. The, team can tell immediately that, their technicians have hit the right spot. John. Boozman grants good see what. You can see quite well here is the lowest layer that, we still had on the drill head and that there is charcoal, in it. So. We already know we're in the middle of the occupation, layer, but. I can't say I'm surprised, because we already knew from the geomagnetic data that there's a structure here which, we've already been able to classify fairly, accurately. If. We hadn't found this it'd be an indication that we'd messed up our measurements. But. It was accurate, aha. We've. Collected a lot of information without, one's driving our shovel into the soil and what is particularly satisfying. Is what we found in the core sample namely. Charcoal. Through. Radiocarbon, dating. We'll be able to establish how old this charcoal is which. Doesn't mean we'll know how old the ditches, but, that's how we proceed one, step at a time and of course when the botanists, then examine, the charcoal for us we'll know what type of trees were burned here. The. Soil samples, undergo, further testing in Frankfurt, the. Small pieces of charcoal, from the historical. Waste pit are treated with the same tender, love and care as any ancient ceramic. Shard. Finally. The, soil is pulsed, with x-rays, to break down its chemical, components. Knut, Raz man is hunting for a very specific element. A. Minge. Divided. Among a human, excretes, about one kilogram of phosphorus per year in, cattle, it's about 8 kilograms. If. We have a lot of phosphorus it's, probable, that it's from the faeces of humans, and animals. So. It's an early indicator, of the length of time this spot was settled.
Was. This settlement used for a short time or a longer, duration the. Higher the phosphorus impact, the, higher the probability that the settlement, was used for a long time. With, their high-tech equipment, archaeologists. Have pinpointed. Many places, where they could dig but. They, don't because. Digging destroys, traces, that hold out the promise of key insights, with future, as yet undeveloped. Methods. We. Shoulder a responsibility. Archeology. Is a finite, field the. Sites do not grow back and things that have been excavated are lost to research. Unfortunately. This is an inherent, part of archaeological. Excavation. In, Nairobi Suba dissolves comes in your hand. Digital. Archaeology is the future, of historical, research but. Even today we can't do everything on a computer. We're. Standing here in the landscape and we feel what's unique, about it we. See the Hill of Tara we. See the topography we. Get a holistic, sense of the place it's. Not possible to reproduce that in a virtual world technology. Provides us with useful tools but, the archaeologists, still has to do fieldwork.
