the style of a group of 13th–14th-century Italian poets, mostly Florentines, whose vernacular sonnets, canzones, and ballate celebrate a spiritual and idealized view of love and womanhood in a way that is sincere, delicate, and musical. The Bolognese poet Guido Guinizelli is considered a forerunner of the stilnovisti (“writers of the new style”), and the most brilliant poets of the group were Guido Cavalcanti (Cavalcanti, Guido) and Dante himself (in his lyric works). The most prominent minor poet associated with the group was Cino da Pistoia; others were Lapo Gianni, Gianni Alfani, and Dino Frescobaldi.

Several influences prepared the way for the development of the dolce stil nuovo. Among these influences were the troubadour poetry of Provence, which contained a courtly love tradition and used poetic forms that evolved into the Italian sonnet and canzone; the simplicity and mysticism of St. Francis of Assisi and his followers; the 13th-century Sicilian school of poets, who created the sonnet and canzone from Provençal forms and who were the first poets in Italy to use the vernacular; and the philosophical doctrines of Thomism, Platonism, and Aristotelianism, with which all the stilnovisti had contact. Guinizelli's contribution was his own gentle style of poetry as well as the exalted view of woman and love, which he presented in the canzone “Al cor gentil ripara sempre amore” (“Within the gentle heart, love is always sheltered”).

The genius of Dante and Cavalcanti brought the movement to its full power. Dante pointed out in Il convivio (“The Banquet”) that he deliberately chose sweet and musical language for his love poetry, and the lyrics to Beatrice that interlace La vita nuova (The New Life) amply prove his success. His notion of love is a very exalted one: even while she was alive, Beatrice was pictured as an angelic presence, and after her death, Dante gave her the role of his divine guide in La divina commedia.

The beatific quality suffusing Dante's love for Beatrice is somewhat different from that which Cavalcanti expresses in his emotionally complex, often anguished love lyrics. But Cavalcanti, the poet of the complexities of love, contributed some of the finest examples of the dolce stil nuovo, for example, the sonnet that begins “Who is she coming, whom all gaze upon.” Cavalcanti was also the author of a famous and difficult canzone analyzing the nature of love, called “Donna mi prega” (“A lady entreats me”), which suggests the notion that love exists when a man encounters a woman who corresponds to an ideal image in his mind and ceases to exist when this correspondence of images ceases.

The influence of the stilnovisti extended far beyond their own period, affecting the poetry of Petrarch, Lorenzo de' Medici (who consciously imitated them), Michelangelo, Pietro Bembo, Torquato Tasso, Dante Gabriel Rossetti, and Ezra Pound.
