The areas forming the Rock Art Natural Reserve of Ceto, Cimbergo, Paspardo have been object of explorations and publications since the early ‘30s. The protagonists of these first studies were once again Giovanni Marro and Raffaello Battaglia, who discovered and published several engravings, especially in the areas of Naquane, Campanine (called at that time Scale di Cimbergo), Zurla and finally Paspardo, the latter having most of its carvings along the path that can be still walked and is usually known as Scale di Paspardo (Biàl do Le Scale).
After a brief period dominated by the work of the German Franz Altheim and Erika Trautmann the researches started again in the ‘50s thanks to the efforts of Emanuele Süss and, especially, of Emmanuel Anati, who in 1956 drew for the first time the attention of the scholars to the area of Foppe di Nadro.
However only from the early ‘70s systematic documentation campaigns were led in this area. They went on till 1983 when the founding of the Rock Art Natural Reserve of Ceto, Cimbergo, Paspardo encouraged the Centro Camuno di Studi Preistorici, led by Emmanuel Anati, to extend the researches also to Campanine di Cimbergo and several sites at Paspardo. At the end of the ‘80s the newly born associations of the CCSP Valcamonica and Lombardy Department and the Archaeological Cooperative “Footsteps of Man” inherited the studying efforts made on these sites (respectively: Campanine, Zurla and I Verdi the former and Paspardo the latter).
The researches and discoveries which have followed one another with no interruption since that time have produced several studies and scientific contributes. Only recently the first complete publication concerning a rock art area inside the Reserve has been finally accomplished and consists in the volume about Campanine di Cimbergo (102 carved rocks).
