Palazzo Ciacchi houses a rich selection of works from the Moscow Palace depots to complement the collections in the city museums; the exhibition is guided by the theme “Myth and devotion”. Ample space is dedicated to the paintings of the seventeenth century, especially Marche, including Agar and the angel, ascribable to the workshop of Giovanni Maria Luffoli (Pesaro 1632 – 1690), pupil of Simone Cantarini, the Virgin contemplating the Sleeping Child Jesus, from a work by Giovan Battista Salvi called Sassoferrato (Sassoferrato 1609 – Rome 1685) and the delicate and sensual Allegory of the painting of the painter and engraver forsempronese Giuseppe Diamantini (1623-1705). The great Neapolitan painting is testified by Samson and Delilah attributed to Luca Giordano (Naples 1634 – 1705) and by the agitated scene painted by the artist Carlo Rosa (Giovinazzo (BA), 1613 – Bitonto (BA) 1678) in which Samson fights and kills the Philistines with a donkey jaw. The eighteenth-century taste is evident in works such as The Triumph of Venus and the Rape of Europe, in the small painting with a miniaturist character, with the figure of Artemis-Diana e nell’Archimede and the soldier sent by General Marcello of a student of the scholar and painter Giannandrea Lazzarini (Pesaro, 1710-1801).
