The baroque as a spiritual, cultural and religious period of glory can be traced in the architecture and its artistic furnishing in the area of Hartberg. Josef Adam Mölk painted the frescoed interior of the pilgrimage church of Maria Lebing near Hartberg which, in 2009, celebrated the 600th anniversary of the first written record of it. In 1472 the Saint Mary Chapel was transformed into a late gothic church which was enlarged during the baroque period by the annex of two side chapels and was then altered by the transformation of the interior into baroque style. The 300th anniversary of the pilgrimage church initiated Josef Adam Mölks commission to paint the church. He skillfully composed the figurative portraits in the form of cartouches that matched the architecture of the interior and filled the space between with decorative painting, such as ?Rocailles?, garlands and framework. The basic theme is dedicated to Mary, the mother of God. The nave depicts stations of Marys earthly life, the chorus shows heavenly Mary as helper and intercessor for the needed. Mölk also supplied the parish church of Hartberg with frescos and altars and painted the walls of the bishops room in the vicarage. The three locations are presented with a detailed description and iconographical analysis. Josef Adam Mölk and his workshop in Hartberg almost exclusively painted all the religious buildings of that area. The importance he gained is more due to the abundance of his work than the quality of single pieces of art. Mölk can be included among the famous baroque fresco painters to only a certain extent. Nevertheless, his topics and their artistic realization can also be understood by rank and file, at his time as well as today. In order to get to know the quality of Mölks work one must visit the places where they were created. Only there, in their totality, do they exhibit their optimal impact.
