3D scanning gives new insight into 275-year-old Jacobite battlefield


Lidar technology has allowed experts to create a map of the Culloden battlefield, where the last pitched battle on British soil occurred in April 1746. 

Conservationists have accurately recreated the Culloden battlefield using electronic mapping techniques, 275 years on from its last battle.

Experts say the new technology gives “the most detailed understanding” possible of how the landscape looked in 1746, when the final Jacobite Rising “came to a brutal head in one of the most harrowing battles in British history”.

Culloden, near Inverness, hosted the final fight of the rebellion where the army of Charles Edward Stuart (Bonnie Prince Charlie) was defeated by a British government force under William Augustus, Duke of Cumberland.

Early stone technologies found to be much older than researchers thought

Researchers from Kent’s School of Anthropology and Conservation have found that prehistoric Oldowan and Acheulean stone tool technologies are tens of thousands of years older than previously thought, according to a new study. 

The new study, which was published in the Journal of Human Evolution, claims that Oldowan stone tools were developed some 2.617-2.644 million years ago, 36,000 to 63,000 years prior , while Acheulean stone tools date, developed 1.815-1.823 million years ago, were made 55,000 years earlier to what existing evidence suggests.

This discovery was based on a statistical modelling method newly used in archaeology, and provides greater insight into the chronology of human evolution, in addition to their dietary habits and behavior. Oldowan and Acheulea stone technologies helped early humans gain access to new foods, along with preparing animal carcasses.

Scientists Have Unlocked the Secrets of the Ancient 'Antikythera Mechanism'

A digital model has revealed a complex planetarium on the ancient device's face. “Unless it's from outer space, we have to find a way in which the Greeks could have made it,” researchers say.

In the early 1900s, divers hunting for sponges off the coast of Antikythera, a Greek island in the Aegean Sea, discovered a Roman-era shipwreck that contained an artifact destined to dramatically alter our understanding of the ancient world.

Known as the Antikythera Mechanism, the object is a highly sophisticated astronomical calculator that dates back more than 2,000 years. Since its recovery from the shipwreck in 1901, generations of researchers have marveled over its stunning complexity and inscrutable workings, earning it a reputation as the world’s first known analog computer.

The device’s gears and displays cumulatively demonstrated the motions of the planets and the Sun, the phases of the lunar calendar, the position of Zodiac constellations, and even the timing of athletic events such as the ancient Olympic Games. The device also reflects a very ancient idea of the cosmos, with Earth at the center.

Ancient Greek Antikythera Mechanism recreated by scientists

An ancient Greek hand-powered mechanical device for predicting astronomical events has been recreated, offering a fresh understanding of how it worked.

The 2,000-year-old Antikythera Mechanism is considered the world’s first analogue computer, used to forecast positions of the sun, moon and the planets, as well as lunar and solar eclipses.

It was first discovered in a Roman-era shipwreck in 1901 by Greek sponge divers near the Mediterranean island of Antikythera.

Only 82 fragments have survived – about a third of the entire astronomical calculator – leaving researchers baffled about its true form and capabilities

Volunteer researchers wanted for Orkney trade project

 

The University of the Highlands and Islands Archaeology Institute is looking for volunteers to take part in a new project researching early trade in Orkney.

The research is part of the international Looking in from the Edge (LIFTE) project, which is looking at the Northern Isles’ place in European trade networks of the 15th to 18th centuries. The Hanseatic League — an organisation of German merchants that expanded into the North Atlantic in the 15th century – was at the forefront of these networks and although its influence in Shetland has been extensively documented, less is known about the league’s interests in Orkney. And this is where the volunteer researchers come in.

Revive the map: 4D building reconstruction with machine learning


A research team from Skoltech and FBK (Italy) presented a methodology to derive 4D building models using historical maps and machine learning. The implemented method relies on the geometric, neighbourhood, and categorical attributes to predict building heights. The method is useful for understanding urban phenomena and changes contributing to defining our cities' actual shapes. The results were published in the MDPI Applied Sciences journal.

Historical maps are the most powerful source used to analyze changes in urban development. Nevertheless, maps represent the 3D world in the 2D space, which describes the main features of the urban environment but fails to incorporate other spatial information, such as building heights. In 3D/4D city modeling applications based on historical data, the lack of building heights is a major obstacle for accurate space representation, analysis, visualization, or simulations.

Beyond Monuments: Ancient Maya Landscapes Revealed Through Technology


Walking through this lush, tropical forest, visitors may not realize at first that they are among the monumental remains of a large ancient Maya center. Where are all the great stone pyramids, ball-courts, temples, and other monuments so often attributed to great ancient Maya centers? Yet, one sees a tropical landscape that is anything but flat. There is a jungle-shrouded mound here, another one over there. A well-planned walking path winds through what a visitor might describe as the Maya version of the Garden of Eden. Like the very first 18th and 19th century explorers of the Maya world, one sees what could be ancient structures still hidden beneath their canopy shroud. Some of them here have now been partially exposed, betraying what might lie beneath and leaving the rest to the imagination. Visitors soon acquire the impression that this place is very different than any other encountered in the Maya world. Straddling the border between Guatemala and Belize, it is known as El Pilar. It has been explored and studied by archaeologist Dr. Anabel Ford of the University of California, Santa Barbara for decades.
