The family of painters Artari was originally from Campione d'Italia and active already in the XVII century; we find descendants of this family in many European countries (Switzerland, Germany, Netherlands, England). A representative, Maria Luigi Artari settled in Aosta Valley (1832); his three sons, Alessandro, Augusto and Antonio, had the opportunity to form at the Accademia Albertina in Turin and succeed then among the protagonists of the sacred art in Valle d'Aosta in the second half of the XIX century.
