Graduale, so called Sącz Antiphonary, belong to 3 quarter XIII c. (Stary Sącz, Clarisian Library, Segn. 1 and 3). Written in two volumes is divided to de tempore and de sanctis, and mentioned among Francescan Graduales. Except of miniatures, by incipience of sentences there are many drawings, made by a scribe of the antiphons. They imagine people and animals heads. They are called probae pennae. An analysis of drawings guide us to uderstanding that there is no connection between them and the text. Probably a scribe made them for a decoration.
