note: FallowsCat, 552; CattinNR, 289. Music & text ed. EinsteinIM, iii, no.1 (discussed i, 125). Pix was contemporary in Florence with lauda sources, so was probably the setting d’Albizo had in mind given also the formal compatibility between Petrarch’s and d’Albizo’s texts. 4-part setting in PetF/xi (1514) by Eustachius Romanus, ed. LuisiFr, no. 10. In LA424, lauda sent to ‘Ser Matteo, prete in San Lorenzo’. Both settings use Petrarch’s sonnet, though Franco Sacchetti wrote a sonnet modeled on Petrarch’s, with an identical incipit & form, and addressed it to Filippo Villani; ed. AgenoFS, 435. For a discussion of Petrarch’s sonnet and its 16thc. musical settings, see J. Haar, ‘Pace non trovo’: A Study in Literary and Musical Parody, «Musica Disciplina» XX (1966), pp. 95-133.
