London, British Library, 1479.b.6 (2)

In the preface, Zoppio states his desire to defend Petrarch against hostile critics by revealing their mistaken judgements. Zoppio sets the dialogue between Orazio Canobio and himself during a meeting of the Accademia dei Catenati. Zoppio comments on single passages from critical works on Petrarch by Lodovico Castelvetro, Girolamo Muzio, Bellisario Bulgarini and Benedetto Varchi. In a few cases, Canobio asks Muzio to provide his own explanation for a few obscure passages in Petrarch’s poems.
 
In the London copy, the last fol. is missing; Zoppio’s Ragionamenti are bound with other works by Zoppio, Giason Denores, and Bellisario Bulgarini. At fol. K4r, one marginal annotation attributes a remark to Angelo Decembrio ‘Questa fu oppositione di Angelo Decembrio assai prima che del Mutio’.
