Edición: Centro para la Edición de los Clásicos EspañolesDistribución: Servicio Publicaciones. Universidad de ValladolidFocused on two sixteenth-century editions of a medieval Valencian author (Ausiàs March, 1400-59), this book examines how the material transformations of early modern poetic texts at different stages in their publication processâeuros'from the making of the printerâeuross copy, to the typesetting and editing of the book in the printing shopâeuros'entailed thorough changes in the meaning of March's corpus. Printers Juan Navarro in Valencia and, especially, Carles Amorós in Barcelona were responsible for widely disseminating Ausiàs Marchâeuross verses in Renaissance Spain while, at the same time, assimilating Marchâeuross works to other distinct poetics of even higher authority and influence. Notwithstanding the discrepancies between both editorial projectsâeuros'one indebted with cancionero poetry, the other with classical modelsâeuros'the role of Petrarchâeuross vernacular poetry in the overall shaping of both editions was paramount and reveals the existence of remarkably similar interpretive communities in the intellectual circles of the Duke of Calabria and the Duke of Somma, sponsors of the volumes studied here.
