Domenichino was employed by the Cardinal Borghese, to paint in competition with Guido, the celebrated frescos in the church of S. Gregorio at Rome. Both artists painted the same subject, but the former represented the Scourging of St. Andrew, and the latter St. Andrew led away to the Gibbet. Lanzi says it is commonly reported that an aged woman, accompanied by a little boy, was seen long wistfully engaged in viewing Domenichino's picture, showing it part by part to the boy, and next, turning to that of Guido, painted directly opposite, she gave it a cursory glance and passed on. Some assert that Annibale Caracci took occasion, from this circumstance, to give his preference to the former picture. It is also related that while Domenichino was painting one of the executioners, he actually threw himself into a passion, using high threatening words and actions, and that Annibale, surprising him at that moment, embraced him, exclaiming, "To-day, my Domenichino, thou art teaching me"—so novel, and at the same time so natural did it appear to him, that the artist, like the orator, should feel within himself all that he would represent to others.
