Paleographic and above all philological considerations lead to the exclusion of this possibility. It is also identified in the Naples code, National Library, V A 8, dating back to the end of the century. XIV, an apograph, in the text and in the annotations, of the lost Petrarch manuscript with the De re rustica by Varrone: the marginal notes of Petrarchian origin are published in the appendix and compared with the work of Petrarch.
