This stanza could be an implicit allusion to the conventional inventory of 1680, supposedly commissioned by Pietro Mellini himself. One of the main objectives of that inventory was to identify the artists who did the paintings in the Mellini collection (as the following stanzas confirm). It is interesting to notice that Pietro mentions “huomini” in the plural. This seems to imply that the attribution of the paintings was carried out by several experts and not by only one. Nevertheless, Jorge Fernández-Santos Ortiz-Iribas believes that the mention of “various authors,” which also appears in the conventional inventory of 1680, is merely rhetorical; he makes a plausible case for Father Sebastiano Resta as the sole expert consulted.

The spelling of the family surname alternates in historical documents between “Millini” and “Mellini” we also occasionally find the variants “Melini” and “Milini.” “Mellini” became the orthographic form that would survive over time.For more, see Bibliography items about the Mellini Family and Collection. —Nuria Rodríguez Ortega

We can assume that Pietro forgot, or deliberately omitted to say, that this is the first section or “chapter” of the poem. The second section is designated by him as “secondo.”
