This Dictionary, from Turin thanks to Abbot Godofredo Casalis, had the official name "Historical, geographical, statistical and commercial dictionary of the States of His Majesty the King of Savoy" and was composed of 29 volumes.
It was kept at the National Library of Turin, where in 1859 it was consulted by Don Bosco, who noted emblematic places such as Albugnano, the Abbey of Vezzolano, the Castle of Montaldo. Precisely in these places, Don Bosco took the little orphans, involving them in a unique experience.
