 Assumed to be a prisoner of war, the question is raised as to why a Florentine artist was asked to execute such an important Sienese painting.It must be assumed that Coppo was already well known and highly regarded at this time for the Sienese to have commissioned him within a year of the bloody conflict with Florence.The Madonna del Bordone is the only surviving documented work by Coppo and it is believed that his signature and the date were still visible on the painting around 1625.
