Abstract
This article draws attention to two newly identified manuscipts transmitting Henricus Totting de Oyta’s Expositio in Meteorologica: ms. Praha, Národní Knihovna Ceské Republiky VIII.E.6 and ms. Kraków, Uniwersytet Jagielloński, Biblioteka Jagiellońska 674. Interestingly, in the Cracovian manuscript Henricus’ Expositio is combined with the second redaction of Nicole Oresme’s Questions on Meteorology. Based on some sample passages, I will show the nature of this compilation. This will lead to a consideration of the structure and the sources of Henricus’ Expositio. In the final part of the article, I will provide some information about the witnesses of Henricus’ commentary, as well as the incipit and the explicit of each book.
