The codex is a typically humanistic collection of different Cicero’s works. On f. 1r only a foliage frieze is left of the original decoration, while the miniated initial has been removed; a large number of initials are decorated with leafy whirls in red, green and blue, perhaps by the same hand who also drew the decorated capital initial in the Guarnerianus ms. 74. The copyist’s subscription can be read on f. 91v: «Gloria deo sit eterno patri et cetera. Marci Tulii Ciceronis ad Quintum Mucium de amicitia liber explicit. Lavariani per Nicolaum presbiterum de Sanctovito Concordiensis diocesis canonicum Utinensem 1439, 15 kalendas octobres»]. Nicolò di San Vito, notary, canon of Udine and parish priest of Lavariano, transcribed other codices intended for Guarnerio’s library, too; the littera antiqua script he made use of has been assessed as particularly original and non-depending on Florentine models. Next to the Paradoxa text the codex shows copious marginal notations, the majority of which are by Guarnerio’s hand; they have a prevailingly exegetic meaning; other notes, written to make it clear the meaning of words of Greek origin, are an evidence of how the knowledge of that language was precarious.
