Dallo Zibaldone al lessico andata e ritorno: l’Heid. Pal. gr. 129 di Niceforo Gregora e il cosiddetto Lexicon Hermanni

The so called Lexicon Hermanni is a Palaeologan compilation of uncertain author: the work is transmitted as anonymous in most of the manuscripts, whereas a few witnesses ascribe it to Nicephorus Gregoras. This article aims at pointing out new textual evidence for the attribution of the lexicon to Gregoras. As will be shown, some of the quotations of classical authors employed as exempla in the glosses show the same textual variants of some excerpts in Gregoras’ famous notebook, Heid. Pal. gr. 129, suggesting that the latter could have been used as a source to compile the lexicon. Furthermore, the comparison between the lexicon and Gregoras’ notebook provides an insight on the composition of the lexicon itself.
