According to modern summaries, the polyptych was transferred in 1782 from the church of Santa Maria degli Angeli to a chapel of the Collegio Montalto in
Bologna. It was disassembled during the
Napoleonic period in 1808 and reassembled in 1894 in a new frame, a process that caused damage to some original panels. Modern accounts describe the work as probably commissioned by the papal legate
Bertrand du Pouget for the papal complex at Porta Galliera in Bologna, then part of the
Papal States. == Description ==
