Romanelli was in fact an interesting drawing by the painter Giovanni one of the artists chosen by the noble family to Francesco Romanelli (c.1610-1662). Te drawing, design works of art that could be a good means held in the Metropolitan Museum of New York, of conveying their political propaganda (about shows an incomplete proscenium arch of a stage the role of Francesco Romanelli see Oy-Marra with the crest of the Barberini placed at the centre 2007: 303-16). of the architrave. Born in Viterbo, Romanelli, also known as Il Viterbese, from his birth city, or Il Rafaellino, afer Rafaello, was trained in Rome where he studied with Il Domenichino (Domenico Zampieri, 1581-1641) frst, and then with Pietro da Cortona (Pietro Berettini, 1596-1669). It is probable that the latter introduced him to the court of the Barberini family since Romanelli was his collaborator in painting the frescos for the chapel inside Palazzo Barberini (1631-32). Moreover, both Gian Lorenzo Bernini (1598- 1680) and Cardinal Francesco Barberini (1528- 1600) acted as his patrons and helped him in having important commissions (Bruno 2017). It must be considered that Bernini was very infuential in the choice of the artists to be hired Fig. 1. Giovanni Francesco Romanelli (c.1610–1662).

Te stage would have been built along the south wall corresponding to the short-lef side in the above picture (Murata 1981: 35). Te access to the hall was achievable through fve doors, but almost certainly the guests who attended the opera entered from the door in the north corner of the west wall, which leads to the room known as the Salone dei Cento Giorni (the room indicated in yellow in fg. 2). Te reason for choosing this room was probably because it is the largest of the palazzo and is three stories high. Te availability of space ofered the artists several opportunities. Tey could build a raised platform, which allowed the positioning of theatrical devices under the stage to move part of the set design and they could place pieces of machinery under the ceiling. To prevent the audience from seeing the mechanisms it was necessary to erect a proscenium arch that allowed them to be hidden, and this task was most probably given to Romanelli, who designed the proscenium arch displayed in fg. 1.

Tat is why it is important to analyse attribute dates to the epic of Homer, where Apollo the message the noble family wanted to convey. is referred to as χρυσάορος (goldsmith) and According to my interpretation, the character the god by the golden sword who, sent by Zeus, represented on the right (see fg. 3 below), despite protected the city of Troy against the Achaeans its similarity with a personifcation of Justice as (Viscardi 2014: 39-61). suggested by the curators of the Metropolitan Te choice of asking the artists to employ Apollo in Museum, can be better identifed with the god decorating works commissioned by them was not Apollo. Some of the god’s attributes are in fact new to the Barberini as the god was very dear to easily recognisable. both Francesco, and to his uncle, pope Urban VIII (Mafeo Barberini, 1631-1658), for whom the god had a non-pagan signifcance. Although Mafeo had ofen condemned the use of mythological images as one of the main reasons of poetry’s loss of power, Apollo was an exception (Scott 2007: 127-36). Since the beginning of his pontifcate, Urban VIII had liked to identify himself with the sun-god and his virtues as a poet, being himself a writer of poems and music lover. For example, the lost fresco by the painter Andrea Camassei (1602- 1648/49), who decorated the ceiling of one of the rooms on the ground foor of Palazzo Barberini Leila Zammar Leila was entitled Apollo e le Muse sul Parnaso and showed the Pope disguised as Apollo. A further confrmation of the devotion of the Barberini to the god is that in their heraldic deeds they ofen used the image of the sun to represent the pope as the sunny centre of a constellation made up of the other members of the family. Tere are also several other paintings, tapestries, and decorations commissioned by the Barberini referring in some way to Apollo or his attributes (Negro 2007: 447- Fig. 3. Detail from fg.1 52). One of the most elaborate allusions to the mythological character and to his relation with Both the laurel crown and the tree trunk, on Urban VIII can be found in Pietro da Cortona’s which the character leans his lef hand, allude to fresco Triumph of Divine Providence decorating the myth of Apollo and Daphne as reported in the ceiling of the big salone on the piano nobile Ovid’s Metamorphoses.

Unable to possess his a sword on the proscenium arch of an opera beloved physically, Apollo decided to decorate dedicated to a saint? To answer this question, it is his attributes with the laurel to maintain a contact fundamental to consider the plot and the aim of with Daphne’s substance forever (Parker and the staging of this opera, considering the historical ISSN 2421-2679 events of the period.

Evidence for this is to be reafrm his legal authority over the Papal States found in the Allegoria della nascita di Urbano VIII and it might well have been the counter-part image by Andrea Sacchi (1599-1661) and Charles Audran, of Apollo on the other side of the proscenium arch kept in the Bibliothèque Nationale in Paris, in analysed in this article (Rietbergen 2006: 129). which the pope/Jupiter is fed by Melissa the nymph, According to the above analysis, the full view of the who is associated with the bee and is surmounted proscenium arch as it appeared to the audience of by the three bees, symbol of the Barberini family San Bonifazio, while entering the salone soon afer (Faedo 2007: 381-92).
