The main room on the first floor of the Leo-Lev Exhibition Center is the setting for the exhibition Una Singolare Annunciazione, curated by Oreste Ruggiero, Ilaria Boncompagni and sponsored by MIBACT, ABAP Superintendence Lucca and Massa Carrara, Archdiocese of Lucca, Parish of San Gennaro and promoted from the Leo-Lev Center. A Singular Annunciation is an exhibition itinerary that leads to the cultural study of the artistic heritage of the Pieve di San Gennaro in Lucchesia. In a single room - that of Room XI of the Leo-Lev Center - there are two important works in dialogue with each other, coming from the church in the locality of the same name, a hamlet of Capannori. The first, the Archangel Gabriel, is an extraordinary work in terracotta attributed by Carlo Ludovico Ragghianti to the Verrocchio school and by Professor Carlo Pedretti to the young Leonardo da Vinci, considering it the largest of the sculptures ascribed to the Renaissance master.

Carlo Pedretti - the world's leading expert on the art and life of Leonardo - in an episode

of Superquark , in 1999, affirmed that the statue of the Angel has numerous distinctive features of the artist-scientist: from the draping of the arm to the hair, from the face to the setting of the body that suggests “ movement ”. Presumably carried out at the end of the fifteenth century or at the beginning of the sixteenth century and placed in the Pieve di San Gennaro, the work suffered serious damage in 1773 when - according to some documents of the time - it fell to pieces after being hit by a staircase, during the decorations for the feast of the co-patron San Cirillo. The restoration, financed by Leo-Lev, was carried out by the Opificio delle Pietre Dure in Florence.

The other rarity on display is the Madonna del Parto della Pieve di San Gennaro (anonymous artist), a particularly mysterious terracotta sculpture, being the only one of its kind in terracotta, with a natural size of about 1.68 cm (much more than normal compared to the representation of the typical woman of the 1400s) and for the vivid reference to the themes and ways of the Madonna del Parto di Monterchi by Piero della Francesca.

 In a single room, the Leo-Lev Exhibition Center presents visitors with the symbolic value between the Angel and the Madonna gathered in A Singular Annunciation, a sculptural group that the Archdiocese of Lucca, the Parish of San Gennaro and the Superintendence of Lucca and Massa Carrara will want to be placed together again, in dialogue with each other, when the works return to the Pieve di San Gennaro.
