Resumen de Dalle pale "d'eccellenti artefici" del duomo di Siena (1673-1688) alla "Galleria di quadri moderni" di Dresda (1742)
Between the end of Seventeenth-century and the middle of Eighteenth-century, and in particular from the 1720s, some private and public patrons (as the Opera del Duomo in Siena or the cardinal Fabrizio Spada in Rome) commissioned series of painting to first class artists belonging to the differenti Italian schools of painting (especially the Roman, Venetian, Bolognese and Napolitan schools). In the second half of the Eighteenth-century this phenomenon suddenly stops, and it is impossibile to find a case in which, for example, Pompeo Battoni and Giambettista Tiepolo were commissioned a painting, at the same time, by the same patron.
