In the construction of a complicated plot, apart from the dramatic presentation thereof, he achieved a success not to be paralleled by any previous work in Italy, for the difference in the titles of the Aminta and the Pastor fido, the one styled favola and the other tragi-commedia, indicates a real distinction; and Guarini's proud claim to have invented a new dramatic kind was not wholly unfounded . It was this that caused Symonds to speak of his play as 'sculptured in pure forms of classic grace, while describing the Aminta as 'perfumed and delicate like flowers of spring. And lastly, it was this more elaborately dramatic quality that was responsible for the far greater influence exercised by Guarini than by Tasso, both on the subsequent drama of Italy and still more on the fortunes of the pastoral in England.
In 1525 had appeared a work by the Neapolitan Marco Antonio Epicuro de' Marsi, styled in the original edition 'dialogo di tre ciechi, and in later reprints 'tragi-commedia intitulata Cecaria . In this three blind men, one blind with love, another with jealousy, the third with gazing too intently on the sun-like beauty of his mistress, meet and determine to die together.
