In his article the author enumérales the arguments which speak of the hitherto not preserved Mándele's Slovene print from the 16th century or the »Agenda vandalica« (Slovene Ritual). There he refers to the mention of the non-identified ritual at Sv. Jurij in Prekmurje (in the year 1627), to the finds of the up to this time unknown prints from Mandele's printing workshop in Hungary and expressly to the lexicon in Bakoš's handwritten ritual from the year 1785. The author thinks that a reflection of the vocabulary from Mándeles print from the year 1587 is to be found in the newly discovered handscript of Bakoš.
