New technology reveals ancient Rome in the 19th century mural
Scientists have detected hidden under the surface of a precious 19th century mural in the Louvre in Paris, the face of a Roman ancient man.
In the latest achievement in the effort to see what can be found beneath the surface of the great works of art, scientists described the first use of a used security scanners similar to the imaging technology of all airports body to detect the face of a Roman ancient man.
They described the unveiling of the image, as scientists and art historians say perhaps thousands of years, at a meeting of the American Chemical Society in New Orleans. J Bianca Jackson, who said the project, said it was a fresco, a mural or painting done on a wall after application of fresh plaster.
In a fresco painting of the artist gets into the wet plaster and establishes that the plaster dries. Painting becomes part of the wall. The earliest known paintings date from about 1500 BC and were found on the island of Crete in Greece.
“No previous imaging technology, including nearly half a dozen commonly used to detect the images below hidden paintings, fake signatures of artists and other non-visible information on the surface revealed a lost image in this fresco, “Jackson said.
Technology is a new addition to the range of art restorers and scientists use to see beneath the surface and detect changes, including forged signatures and other alterations in a table.
Called terahertz spectroscopy, it uses beams of electromagnetic radiation that lie between microwaves, like those used in cooking stoves, and infrared rays used in TV remote controls. This radiation is relatively low, does not damage the paint and does not involve exposure to harmful radiation.
“The terahertz technology has been in use for some time, particularly in quality control in the pharmaceutical industry to ensure the integrity of pills and capsules, biomedical imaging and even internal security with scanners whole body see under clothing to airport security check points, “said Jackson, who is now at the University of Rochester.
Artists, including some of the greatest masters paintings sometimes reused, erasing the original image or covered old paint new works. They often done to avoid the expense of buying a new canvas or to improve the colors and shapes in an earlier composition.
Scientists have turned to the terahertz technology when suspicions emerged that a picture can be hidden in the brush strokes of a precious fresco of the 19th century, three houses Weapons spears, the Campana collection of the Louvre.
