The plenarium of Naceradec belongs to the ten eldest diocesan missals which have been preserved in Bohemia and Moravia. It can be dated to the second decade of the 14th century according to its script and decoration. Only a small part of the ordinarium and de tempore of the proper missal have been preserved. The original calendar was substituted for a new one at the beginning of the 15th century. Municipal scribes recorded in the free margins of the codex a series of memorial entries which became a pretious source of knowledge of the everyday life in the second half of the 16th and in the first half of the 17th centuries.
