The exhibition Il meraviglioso mondo della natura held at the Palazzo Reale in Milan between spring and summer of 2019 provoked a lively debate. Curated by the authors of the article, the exhibition reconstructed the so-called Sala del Grechetto from Palazzo Visconti (then Lonati and Verri), a large hall decorated with vast canvases representing Orpheus, Bacchus and some two hundred animal species. In the 18th century the hall belonged to the Verri family, though was very probably designed by Alessandro Visconti, huntsman of Ferdinando II de' Medici, in the second half of the previous century. The work of reconstructing the setting, carried out by Margherita Palli and Pasquale Mari, started up a debate over its actual appropriateness, on the use of the rebuilt complex for public fruition and more in general on the authority, or otherwise, of art historians to be involved in the reconstruction of settings.
