The proposed paper will focus on a manuscript which contains a collection of copies of several sermons preached by Johannes Sculteti, a lector and prior, an Augustinian hermit, in Wroclaw on several occasions between 1427-1431. In his speeches for various communities in the city and ecclesiastical gatherings on the patronal feasts, he spoke about the disasters in Silesia and discussed their causes. However, the written evidence presents another layer for analysis: the texts were copied in a manuscript codex which belonged to Nicholas Tempelfeld of Brzeg (d. 1474). His interest in the anti-Hussite rhetoric of an earlier author was not only academic, as in the 1450-60s he led an active political life in Wrocław, and was one of the leaders of the opposition against the Bohemian party represented by George of Poděbrady. The paper will present the evidence of sermons delivered by John Sculteti and discuss two layers representing two time periods which the textual evidence speaks to.
