The frequency of his commissions contributed, perhaps, to put him upon a more easy method, no less than his own incredible genius for execution and despatch. He produced a hundred and six altar-pieces, and a hundred and forty-four large pictures for princes and other persons of distinction, without including numbers of others painted for private persons, Madonnas, portraits, half-length figures, and landscapes, in which the rapidity of execution is highly original. Hence he is by no means rare in collections. The noble Zolli family at Rimino possesses about twenty of his pieces, Count Lecchi at Brescia also a great number; all perfect and polished according to his manner. Among these is a portrait of a friar of the Osservanti, his father confessor, quite a miracle of art. Guercino's school greatly flourished at Cento, in Bologna not so much, owing to his own choice of having his two nephews the Gennari, and a few other intimate friends with him, which led him to exclude strangers in some degree from his studio. Few Bolognese artists, therefore, belong to this master; such as Giulio Coralli, whom Orlandi, a contemporary writer, gives as pupil to Guercino at Bologna, and of Cairo at Milan, and who, Crespi adds, was much employed at Parma, at Piacenza, and at Mantua. He was a better portrait-painter, if I mistake not, than a composer. Fulgenzio Mondini was an artist of more merit; he painted two fresco histories in the church of S. Petronio at Bologna, relating to the Paduan saint. He died young at Florence, where, after having painted some time for the court, he was employed by the Marchesi Capponi to decorate their villa of Colonnata, and his memory has been honoured with a long eulogy by Malvasia. The latter declares that he knew none gifted with qualities that promised so much in that age, and conjectures that had he survived he would have become the first fresco painter of his age.
