(“A mask from the region of Piedmont, it first came on stage as a puppet, only later becaming [sic] more typical of the marionette theatre. It seems to derive from a character known as Gironi d’la crina (dialect; in Italian: Gerolamo della scrofa) – which had been created around 1630. At the beginning of the XIX century, the name of this puppet got his operator Giovanni Battista Sales into trouble, because, though common people strongly appreciated its humour, neither the Doge of Genoa nor the brother of Napoleon could stand the fact it had their same Christian name. Sales was expelled both from Genoa and Turin, and confined in Caglianetto d’Asti, where, probably, determined to avoid more problems, he changed the name into Gioan d’la douja (dialect; in Italian: Giovanni della duja) which was contracted into Gianduia”)
