Domenico Zampieri, otherwise Domenichino, is at this day universally esteemed the most distinguished pupil of the Caracci; and has even been preferred by Count Algarotti to the Caracci themselves. What is still more, Poussin ranked him directly next to Raffaello; and in the introduction to the life of Camassei, almost the same opinion is given by Passeri. During the early part of his career his genius appeared slow, because it was profound and accurate; and Passeri attributes his grand progress more to his amazing study than to his genius. From his acting as a continual censor of his own productions, he became among his fellow pupils the most exact and expressive designer, his colours most true to nature, and of the best _impasto_, the most universal master in the theory of his art, the sole painter amongst them all in whom Mengs found nothing to desire, except a somewhat larger proportion of elegance. That he might devote his whole being to the art, he shunned all society, or if he occasionally sought it in the public theatres and markets, it was in order better to observe the play of nature's passions in the features of the people;--those of joy, anger, grief, terror, and every affection of the mind, and to commit it living to his tablets; and thus, exclaims Bellori, it was, he succeeded in delineating the soul, in colouring life, and rousing those emotions in our breasts at which his works all aim; as if he waved the same wand which belonged to the poetical enchanters, Tasso and Ariosto. After several years' severe study at Bologna, he went to Parma to examine the beautiful works of the Lombards; and thence to Rome, where he completed his erudite taste under Annibal, who selected him as one of his assistants.
