It was made possible by the generous grants from the Ny Carlsberg Foundation and the Augustinus foundation. First and foremost I thank my academic advisors Jane Fejfer (associate professor, classical archaeology) and Jan Stubbe Østergaard (research curator, NCG): without them this dissertation would not have realized. I am grateful for their invaluable support and insightful guidance throughout the entire process of writing the dissertation at hand. I am privileged to have been affiliated with both the University of Copenhagen and the NCG. I have greatly enjoyed the expertise housed at both institutions and their inspirational environments. I am particularly grateful for having had the opportunity to become involved with the Copenhagen Polychromy Network and the international Round Table conference held once a year. I am especially indebted to conservators Maria Louise Sargent and Rikke Hoberg Therkildsen for the many hours they spent on examining the Roman marble portraits and on discussing the results with me. Also, a special thank goes to Flemming Friborg, director at the NCG, for taking his time to evaluate on some of the philosophical issues related to my work. Exploring paint on marble portraits requires knowledge on what marble and paint is. I am therefore grateful for having had the opportunity to benefit from the expertise knowledge of Mikkel Scharff and Jørn Bredahl-Jørgensen, associate professors at the School of Conservation in Copenhagen. A thank also goes to Lars Henningsen and Mette Moltesen, former head of conservation and museum curator at the NCG, for sharing their many years of experience with the collections at the NCG with me. Furthermore, I warm thank is due to painter Per Kapper and sculptor Matthew Simmons for the fruitful and inspirational collaboration on the project of making the physical reconstruction of one of the portraits. I would also like to thank the University of Nottingham for accepting me as visiting scholar. I particularly thank associate professor Katharina Lorenz for arranging my stay and taking good care of me. Finally I am full-heartedly indebted to my family, friends and co-workers who have encouraged me throughout the entire process. I am especially indebted to Lars Hummelshøj for his gentle support and for expertise assistance in making the Photoshop reconstructions of the portraits. Without his patience, love and support I would not have been able to complete my work. 5 Dedicated to my father, Christian Henrik Skovmøller, 17.11.1952-20.11.2012. 6 ABBREVIATIONS Latin and Greek texts are cited according to the guidelines for abbreviations listed in the Oxford Classical Dictionay (4th Edition).

The polychromy of the white marble portraits was made from many different, externally created and applied colour effects, including inlaid eyes, metal attachments and attributes, gilding and painterly effects; and it is the combination of these elements, with particular emphasis on the painterly effects, that concerns this dissertation. Increased awareness over the last 15 years of the fact that white marbles were originally painted confronts established scholarly research traditions with theoretical and methodological obstacles. These obstacles consist in implementing the radically transformative new information into studies of the well-known – sometimes familiar – pieces of material culture. The fact that most marble works were once painted has always been lurking at the corners of art historical and archaeological scholarly research, yet this fact has never been fully incorporated into scholarly practice. Throughout the twentieth century, little attention was paid to the original colours of marble sculptures, with one major exception being Patrik Reuterswärd’s 1960 monograph Studien zur Polychromie der Plastik.1 When a statue of Augustus was discovered in 1863 in Prima Porta, just outside Rome, it revealed extensive remains from its once painted colours (fig. 0:1 and 0:2). The statue of Augustus from Prima Porta continued to display extensive colour remains (although most of them have faded away), but general scholarly interest has gravitated towards its context, its iconography, its style of hair and its Greek assimilations. Compared to the comprehensive attention paid to this single portrait statue, minimal focus has been paid to its original polychromy since it was first discovered; that is, until now. In the early 21st century, the sculpture was restored in the Vatican Museum, and at the same time systematic examinations of the remaining paint were conducted.2 Results showed that the statue was originally painted with various pigments, including madder lake, ochre of red, brown and yellow hues, carbon black and, perhaps, also cinnabar in combination with the madder lake.3 Later, following the invention of VIL imaging, Egyptian blue was added to the knowledge base concerning the statue’s original colouration (fig. 0:3). With aid from modern technology, the 1 Reuterswärd 1960; Østergaard 2004A, 11-13; Østergaard 2004B, 32-33; Brinkmann 2014, 35-36. 2 Liverani 2003, 188. 3 Spada 2003, 196; Liverani 2003; Liverani 2004; Satamaria, Morresi, Agresti and Pelosi 2014. 8 pigments embedded in the marble surface of the statue have been located and identified (some of them not even traceable with the naked eye), and the remains experimentally reconstructed on a plaster cast of the original (fig. 0:4).4 Together with the portrait of Caligula in the Ny Carlsberg Glyptotek (NCG) (fig. 0:5)5, the statue of Augustus from Prima Porta was the first examinations of a Roman marble portrait once having had more or less fully covering paint applications. Since then, more pieces have joined, and knowledge on how and why the marble portraits were once painted is steadily growing. This dissertation will contribute to this growing scholarly field by being the first thorough examination of the original paint on Roman white marble portraits.
