Abstract

The analysis of antique papyrus documents using an external milliprobe is described. Missing characters of text in the documents were made visible by means of PIXE analysis and X-ray imaging of the areas studied. The contrast between the papyrus and the ink was further increased when the information contained in all the elements was taken into account simultaneously using a multivariate technique (partial least-squares regression).
