The nine ceiling paintings in the previously little-researched state hall (dated from about 1670) of the Palais Dietrichstein in Graz are considered to be the first works attributable to the Inner Austrian painter Franz Steinpichler (1630-1714). Designed in the decoration scheme of quadri riportati, they depict scenes taken from Ovid's Metamorphoses, with a five-part Phaeton cycle playing the most prominent role. The painting in the middle of the ceiling aims to glorify the princely house of Dietrichstein-Meggau, with the three other pictures each showing a different couple of Ovid's Metamorphoses.The main aim of and core part of this thesis is the first detailed description of the ceiling paintings followed by an analysis and interpretation of the pictures. For this purpose both the literary sources of Ovid and the engravings by Hendrick Goltzius, which served the artist as a template, were used. A series of stucco reliefs in the so called Knights' Hall in Bernstein castle, together with a series of engravings by Antonio Tempesta on which they were based, were used to provide further examples for comparison. In addition, a detailed photo documentation of the paintings was made.Furthermore, this thesis deals with primary literary sources and the dating of the paintings as well as the possible reason for their creation, namely a wedding. Other issues that are discussed are the influence of the clients and their possible self-expression in the paintings. In this context the thesis examines why Ovid's Metamorphoses and in particular the Phaeton cycle were selected as subjects. Some aspects of the thesis are dedicated to the life, work and style of the artist himself, as well as to the placing of his works in the context of the development of Styrian Baroque paintings of the 17th century. This thesis concludes with the examination of the latest expert reports relating to the restoration of the paintings, which are in extremely poor condition.
