The fulcrum of the exhibition is the rearrangement of the triptych which Battisto di Gerio painted in 1417 for the Church of San Quirico all’Olivo, which is private property and closed for worship today and whose parts were dispersed between Lucca, Avignon and Philadelphia. It refers to the Madonna in trono con Bambino (Mother Mary and Child on the Throne), in the Johnson Collection in the Philadelphia Museum of Art, which made up the central part of the work of art; Saints Giuliano, Luca and a Donor, purchased in 1980 by the Musée du Petit Palais di Avignon, made up the left side of the triptych; and the panel which portrayed the Saints Quirico, Giuditta and Sisto Papa, purchased in 1999 by the Ministry of Cultural Heritage and Activities, and destined to the Museo Nazionale di Villa Guinigi of Lucca, representing the right side.
