“…To facilitate the reading of the palimpsests, we apply the algorithms of the Layer Amplification Method (L.A.M. ), 25 which combine all the filters, several formulas with several parameters to obtain 1650 images reflecting light/matter interaction at different depths in the thickness of the parchment.…”

The eighth-century Latin manuscript Milan, Veneranda Biblioteca Ambrosiana, L 99 Sup. contains fifteen palimpsest leaves previously used for three Greek scientific texts: a text of unknown authorship on mathematical mechanics and catoptrics, known as the Fragmentum Mathematicum Bobiense (three leaves), Ptolemy's Analemma (six leaves), and an astronomical text that has hitherto remained unidentified and almost entirely unread (six leaves). We report here on the current state of our research on this last text, based on multispectral images. The text, incompletely preserved, is a treatise on the construction and uses of a nine-ringed armillary instrument, identifiable as the “meteoroscope” invented by Ptolemy and known to us from passages in Ptolemy's Geography and in writings of Pappus and Proclus. We further argue that the author of our text was Ptolemy himself.

When conducting forensic examinations of cultural property, various scientific and technical methods are used, including traceological research methods developed within the framework of forensic science. Traceological research methods are used, in particular, when it is necessary to study knots and loops: analyzing the images of knots and loops in works of painting, graphics, sculpture when resolving disputes regarding the attribution of products; decorative antique objects made using cords, ropes, threads, modern art installations; antique items of historical value. In this case, mainly classification and diagnostic tasks are solved. In some rare cases, identification problems can also be solved using the existing reference and information databases of knots and other fastening methods available to forensic tracers. New possibilities for studying knots and their images using artificial intelligence technologies seem promising.
