A century ago, in a mostly erased manuscript in Brussels, Andre Boutemy discovered parts of the lost hexameter commentary on Ecclesiastes by the famous eleventh-century chronicler and scholar Sigebert of Gembloux. This paper in progress will show that the commentary indeed survives and is able to be fully reconstructed.

Behind the modern Spanish words matiz and matizar, and their cognates in Portuguese and Catalan, lies a curious Medieval Latin verb, matizare. Using new manuscript evidence, the paper critiques the currently accepted etymology of this word, from Gr. lammatizein, and proposes instead a derivation from L. haematites, while offering a new model for the word's semantic development from the twelfth through the fourteenth centuries.

Examining the connection between catena commentaries and marginal glosses to Plato's Timaeus in twelfth-century manuscripts, this paper argues that the decline in Platonic studies at the end of the twelfth century is substantially linked to the broader shift away from lemmatic commentaries to other forms of secondary scholarship in the same period.
