The Assisi Chartula by the hand of Saint Francis: Non-destructive characterization by spectroscopic spectrometric and optical methods

This arrangement is characterized by having the spatial and spectral information on two mutually orthogonal directions imaged on the detector, with submillimetric spatial resolution and a spectral resolution better than 2nm. Additionally it is possible to implement time resolved measurements on the nanosecond scale by controlling the electronic detector gate. Just two examples of writings by the hand of S. Francesco are known to exist: a letter to Brother Leone, kept in the archives of Spoleto cathedral and the Chartula, displayed in the Hall of Reliquaries at Assisi's Sacro Convento. For the first time in its history the Chartula has undergone a series of non-destructive analyses, with the object of establishing its current state of conservation and the types of inks used in its making. A new display case has been designed and built by RMP for the improved conservation of this precious document. The new housing substitutes an ancient case, which was located inside the original reliquary.
