Scientists from the University of Arizona, the U. The map, drawn in ink and measuring Mellon, known for his many important gifts to Yale, and, at Mellon's request, subjected to an exhaustive six-year investigation.
Is the Vinland Map, which depicts Viking forays to North America, a priceless document made before Columbia's voyage to the New World, or is it a brilliant 20th-century forgery? Take a close look at the map and its suspicious details with this high-resolution and annotated image, and decide for yourself. Is the famous map of Viking adventures in North America a fake?
Jump to navigation. A team of scientists has used the National Science Foundation-University of Arizona Accelerator Mass Spectrometer to radiocarbon-date the parchment of the famed "Vinland map. The parchment dates to A.
The report will appear in the Dec. The Vinland Map is a drawing of Iceland, Greenland and the northeastern seaboard of North America that has been dated to the midth century, suggesting that Norse explorers charted North America long before Columbus. The map, which has had a contentious history since its discovery in the s, resides at the Beinecke Rare Book and Manuscript Library of Yale University. Olin, who was involved in the Radiocarbon research, wrote the new Analytical Chemistry paper in response to the controversy sparked by last year's dueling papers.
Revisiting his notes in to draft a detailed reply to the abbreviated public version of Cahill's report, Walter McCrone chose the wrong sample to illustrate a "typical" black ink particle, selecting one which had been found only loosely attached to the ink. InMcCrone visited Yale to take new microsamples from the map, partly to check his earlier results, and partly to apply new techniques. Photomicrographs taken at 1 micrometer intervals through the thickness of ink samples demonstrated that the manufactured anatase particles were not just sticking to the surface as Cahill's criticisms had implied, and Fourier transform spectroscopy identified the ink's binder as gelatin, probably made from animal skin.

In the mid s, a sample piece was cut from the bottom of the map for Carbon dating, and after nearly a decade of silence, the results were published in Two measurements dated it as contemporary and the rest dated it to consistent with the age determined from the watermarks and writing on the map. The two anomalous measurements do not actually date the manuscript as contemporary.
The parchment is dated to AD Donahue, D. All carbon in living matter contains the radioactive carbon isotope, carbon, to the extent of 1 part in 10 All the time, carbon is being formed, as cosmic rays bombard our atmosphere; and eventually the carbon enters our bodies through the food chain.

The Vinland map is claimed to be a 15th-century mappa mundi with unique information about Norse exploration of North America. It is very well known because of the publicity campaign which accompanied its revelation to the public as a "genuine" pre-Columbian map in In addition to showing AfricaAsia and Europethe map depicts a landmass south-west of Greenland in the Atlantic labelled as Vinland Vinlanda Insula.
