Oratorio di Santa Cecilia, Bologna
The Oratory of Saints Cecilia and Valeriano is a religious site in central Bologna, found on Via Zamboni, contiguous to the portico of the church of San Giacomo Maggiore. The oratory was built at the site of a Romanesque church commissioned by the then ruler of Bologna Giovanni II Bentivoglio. It was frescoed starting in 1505 by series of Renaissance painters associated with the Bentivoglio court, including Francesco Francia, Lorenzo Costa and Amico Aspertini. The frescoes cover the walls flanking the oratory entrance. In ten panels, divided by pilaster strips in decorated grotteschi, scenes from  the life of Saint Cecilia and her husband Valerian are described. The individual attribution of all the panels is not entirely clear; they depict: Other artist involved in these or later works include Francesco Cavazzoni, Tiburzio Passarotti (Son of Bartolomeo), Cesare Baglioni, Cesare Tamaroccio, Giovanni Maria Chiodarolo, Bartolomeo Bagnacavallo, and Biagio Pupini. The main altarpiece was a "Crucifixion" by Giacomo Francia, now held in the Pinacoteca Nazionale di Bologna, as well as a 14th-century fresco once outside the chapel by Giovanni di Ottonello.
