Mattia Bortoloni (31 March 1696 – 9 June 1750) was an important painter of the early Italian Rococo period. He began his career as a student of Antonio Balestra of Verona and was active throughout northern Italy. Biography For many years the growth of Bortoloni's reputation was constrained by two factors. First, his work was heavily centered on frescos (that is, wall paintings created in wet plaster), which generally must be viewed on-site and are often located in places of restricted accessibility. Second, some of his most important work became, through the years, anonymous or mis-attributed to others, including his better-known rival, Giovanni Battista Tiepolo, who was born in the same year. Since 1950, however, appreciation of Bortoloni's work has been revived by new scholarly discoveries and several exhibitions with informative catalogs. The first major breakthrough came in 1950 with publication of Nicola Ivanoff's provocative discovery that the mysterious and anonymous 104-panel fresco cycle at Villa Cornaro-Gable, the acclaimed villa in Piombino Dese designed by the Renaissance architect Andrea Palladio in 1551, was in fact the precocious work of Bortoloni, executed in 1717 when the artist was just 21 years old. The new attribution and the dating of the frescos moved Bortoloni out from Tiepolo's shadow so that he could be seen as an innovative artist in his own right. Antonio Romagnolo made the point when he noted that the fresco cycle at Villa Cornaro introduces "a richness of new elements that anticipates the rococo of Tiepolo." The early 20th century brought the further discovery that Bortoloni had flexibly based his imagery at Villa Cornaro-Gable in large part upon an illustrated Bible published in Amsterdam in 1700, apparently in response to the requirement of the patron, Proc. Cornaro. Another event prompting reevaluation of Bortoloni's work was the ambitious program launched in 1982 to restore Bortoloni's most spectacular work, the cupola of the Sanctuario Basilica "Regina Montis Regalis" in Vicoforte, south of Turin. Bortoloni's immense fresco ceiling spans one of the world's largest free-standing cupolas, more than 6,000 square meters in area. Other notable Bortoloni works can be found in: (Venice) the Church of S. Nicolò da Tolentino and Ca' Vendramin-Calergi: (Veneto) the parish churches of Castelguglielmo and Rovigo; (Lombardy) Palazzo Clerici in Milan and the Cathedral in Monza; (Piedmont) the parish church of San Lorenzo and Palazzo Falletti di Barolo in Turin.
