In 1618 Antonio Mirandola – the young Guercino's patron – asked Oliviero Gatti to engrave certain of Guercino's drawing studies that had been created as models for his own pupils. Twenty-two plates were produced and in 1619 were published. The volume was dedicated to Ferdinando Gonzaga, Duke of Mantua.
