In comparison with the art production at Nurnberg or at the cities of the so-called Danube School at the end of 15th century stands the simultaneous painting at Munich in the background. Therefore is sometimes forgotten, that there, in this period, a painter Jan Polack with his workshop was active. To his important customers/patrons belonged the dukes Sigmund and Albrecht of Wittelsbach and the Bavarian monasteries (Weihenstephan near Feising), for which he made few altars or portraits. A most of these altars were after that removed from the original sacral areas and today they are presented in the Bavarian National-museum at Munich or in other galleries. Only a few altars, for example three altars for the chapel in Blutenburg near Munich, have been staying on the original place in this small chapel. These Master thesis would like to compare his most representative pictures in the context with the others paintings, which were created in the middle or at the end of the 15th century in Bavaria (circle of Hans Pleydenwurff, Wolfgang Katzheimer etc.). This comparison can help to find the sources of the Polacks artistic expression. A special attention should be devoted his cooperation with Mair of Landshut, because few pictures of Polacks altar from the church of St. Peter in Munich have just been to Mair inscribed. It is also important to point to same compositional connections between the altar-pictures of Jan Polack and the graphics (Master E. S., Martin Schongauer) One highly-valued contribution of this thesis could be a capitol about the possible inspiration of the Polacks artistic expression for the artists, who came from Bohemia and who have been working here for a long times, but who could gain their training in the Bavaria (Munich). At the literature (Jaroslav Pešina) was one opinion expressed, that an altar in a church in Chudenitz concludes the formal features, which reveal a connection to the art at Munich in the middle of the 15th century. However, other authors (Roman Lavička) think that the painted boards of an original altar of Doudleby were inspired by Polacks artistic expression, although any concrete related features were not in the literature mentioned. It is appropriate too, point to the several compositional connections between the pictures of Jan Polack und a so-called Master of an altar from Litoměřice. This anonymous Bohemian painter, who is knowed only according to his most important commission, would be supposed to study in the Bavaria (an artistic circle of Rueland Frueauf at Passau) at the end of the 15th century. It is possible, that he could visit Munich und he could be inspired by the Polacks paintings.
