The research considered the study of the Tasso expositions accompanying the love rhymes, published in Mantua in 1591 by the publisher Osanna. Graphically contiguous to the text, the commentary gives the print a semblance of prosimeter, strongly characterising the mise en page and constituting a factor of extreme cohesion between the rhymes. The commentary is organised in notes of various extensions and their classification, carried out according to a precise taxonomy, is functional for a greater understanding and evaluation of Tasso’s exegetical practice: alongside explanatory notes, placed to clarify the verses, there emerge metrical, rhetorical and semantic observations, as well as annotations in which the author makes explicit the models of his poetry, alluded to by allusion or precise quotation. Written at a distance of time from the writing of the texts, the commentary is thus part of Tasso’s composite corpus of theoretical reflections on lyricism, expanding, therefore, a production that takes the form of works significantly influenced by the genre chosen and practised by the author. The complexity of this commentary emerges, again, in the unfolding of the variegated literary and philosophical substratum that underpins the lyric experience and gives to readers a specific image of the author.
