From 1837 to 1839, Liszt crossed Italy with Marie d'Agoult. After the first volume of the Years of Pilgrimage, Switzerland (1835/36), he recorded new musical impressions of his journey, now devoting himself to themes relating to poetry (Petrarca, Dante) and the fine arts (Raffael, Michelangelo ). Liszt reworked his works many years later and had them published in 1858 under the following title: Years of Pilgrimage, Second Year, Italy. Commonly called Dante Sonata, the Sonata After a Reading of Dante is the most extensive and most elaborate piece in the collection (cf. also the separate edition HN 981). The Sonetto 104 del Petrarca is just as popular (separate edition, see HN 982). In 1861, Liszt added Venezia e Napoli in addition to the second notebook (see HN 985 for the separate edition of this piece by Henle).
