On page 114 of a Greek manuscript referenced as 'Cod. Graec. Monac. 582a' in the National Library of Bavaria, a few pieces of Hungarian text have been found and named as Munich Heritage. Most of the codex contains copies of writings previously published in a printed form between 1495 and 1512-13. The manuscript was worked on by several hands, but a substantive portion of it can be attributed to the Benedictine monk Johannes von Grafing. The Hungarian texts include prayers (translations of Ave sanctissima, Pater noster, Ave Maria, Credo, Magnificat) and some language teaching material. Some of the prayers can be found in several versions. This paper gives a transliteration of the Hungarian texts, with philological notes and commentaries. The paper is accompanied by a photographic reproduction of the Munich Heritage.
