1,600-year-old frescoes undergo cleaning by laser

The 1,600-year-old frescoes in the Catacomb of St. Domitilla have been cleaned using laser technology. Laser instruments were used to burn away the dirt and deposits, leaving only the rich colours of the frescoes beneath. “When we started work, you couldn’t see anything – it was totally black. Different wavelengths and chromatic

Digital model of cat mummy created

Researchers using photogrammetry technology and a CAT scanner have digitally recreated in 3D a model of an Egyptian mummified cat. By blending the digital model of the mummified cat with the internal CAT scan, the team were able to create an ‘outside and in’ animation of the entire artefact. The scan revealed

Laos’ Plain of Jars recreated in virtual reality

Archaeologists have recreated in virtual reality the Plain of Jars in Laos. The researchers will also use virtual reality to study other archaeological sites at the Plain of Jars, many of them located where undetonated American bombs left over from the Vietnam War make it too dangerous to dig. The virtual-reality project

X-rays used to reveal hidden texts in Egyptian coffins

New imaging techniques are being used to find and read hidden text written in coffins made for middle-class Egyptians. It’s a space-age solution to an ancient problem. For more than a century, archaeologists have dismantled mummy coffins, also known as cartonnage, in a hunt for literary treasure. In ancient Egypt, undertakers

Drones used to monitor looted Bronze Age sites in Jordan

UAVs are being used to monitor the rate of ongoing site damage at Bronze Age sites in Jordan. The use of unmanned aerial vehicles -- drones -- to document and monitor a ravaged landscape on the Dead Sea Plain in Jordan for the past three years reveals that looting continues at

Drones used to find Medieval Irish sites

Aerial surveys performed by drone aircraft are being used to help locate new dig sites in Ireland. "We have collected an unprecedented amount of digital data," Finan said. "The 3D landscape data allows us to see minute changes in the topography that can be defined as structures and human occupation. The

Charred ancient scrolling unwrapped “virtually”

Digital technology has been employed to "unwrap" a charred scroll found during excavations of the synagogue at Ein Gedi. It turns out that part of this scroll is from the beginning of the Book of Leviticus, written in Hebrew, and dated by C14 analysis, a form of radiometric dating used to

Face of 7,000-year-old woman reconstructed

Researchers have recreated in 3D the face of a woman who died 7,000 years ago in Tehran, Iran. He told Mehr News that to develop a 3D documentation, “we used whole parts of the skeleton and the principle of symmetry of human skeleton to reconstruct the missing parts or parts which
