Each stained glass window is identified by location, town, building and, if there are several stained glass windows in the same place, they are numbered consecutively. The dimensions are given in centimeters. The numbering system used follows the CVMA Guide: the location of each window is numbered starting from the Church apse, north aisle (n), south aisle (s). See the Church maps. The position of each panel in a stained glass window is specified horizontally by lower case letters and vertically by Arabic numerals. See the window graphs.
The locations, the churches names, the artists' names also are indicated in Italian.
