The study answers the question who delivered the first sermon at the funeral of Emperor Charles IV, held on 15 December 1378. The second funeral oration was delivered by Adalbert Ranconis de Ericini. Until the 1960s, Archbishop John Očko of Vlašim was considered the author of the first eulogy, or rather sermon, without any reservations. It was Jaroslav Kadlec who suggested the possibility that the oration at the Emperor’s casket was delivered by the successor of Archbishop John Očko of Vlašim, John of Jenstein. The author also expresses the opinion that the Archbishop John Očko of Vlašim remained in active service until the beginning of March 1379; thus, it can be proven that he held funeral services for the deceased Emperor. It is likely that both orators were appointed by the current Archbishop John Očko of Vlašim, who was carrying out other duties at the funeral in his capacity as Archbishop. and František Šmahel.
