1) There is an English abstract:
In this report we summarize the main results of the first in-depth measurement of the Shroud of Arquata, a 1:1 copy of the Shroud of Turin which dates back to 1653. The most peculiar feature of the Shroud of Arquata is the front and back human footprint which is not produced by apparent drawings or painting as in the other copies of the Shroud. In the frame of an agreement between the City of Arquata, the Technical Unit Application of Radiation of the ENEA Centre of Frascati and the Institute of Complex Systems of CNR, we used sophisticated optical and spectroscopic non-invasive technologies, suitable to the study of Cultural Heritage.
The elaboration of experimental results allowed to obtain scientific data apt to suggest the possible origins of the double image, of the stains simulating blood and of the false patches embedded on the Shroud of Arquata.
In addition, the experimental data allowed to develop a plan for the proper long-term conservation of the Shroud of Arquata.

During the restoration of the church of S. Francesco at Borgo di Arquata del Tronto , in the province of Ascoli Piceno , in 1980 is found a double urn of gilded wood , hidden in the niche of an altar . Inside there is a large sheet folded and a scroll. On the sheet is visible footprint front and back of a human body , and the center is the word ‘ EXTRACTVM AB ORIGINAL ‘ (extract from the original, which is sanctified by direct contact with the real relic ) .
It is a copy in 1: 1 scale of the Shroud of Turin , the most valuable and controversial relic of Christendom [ 1 ] . Copying Arquata accurately reproduces the image and stains on the Shroud of Turin : in addition to the double human footprint are noticed reddish spots in the side , feet and head , the drawings that recall the patches corresponding to burns inflicted to the Shroud Turin by fire in 1532 , and even water stains .
However , there is one important difference between the Shroud of Arquata and the other 50 copies of the Turin Shroud survived to our times [ 2 ] : at first glance , the impression you do not recognize human brush strokes , nor drawings , nor anatomy of the face and body . Conversely , the origin of painting and art of the other copies of the Shroud is evident even at a superficial analysis [ 2 , 3 ] .
