This paper presents the preliminary results of an investigation on the unexplored topic of polychromy on provincial stone sculptures from the Roman provinces in Germania through the innovative application of heritage materials science techniques. A group of three life-sized statues dating to the 1st Century CE recovered from Ingelheim, near Mainz, retains remarkably well-preserved traces of pigments. These are ripe for emerging non-invasive technologies supplemented by micro-sampling to validate results and provide information relating to mixing and layering not available to the naked eye. The most strikingly visible areas of extant polychromy were retained on the sculpture of a young woman, reported on here as the first phase of this programme of research. The results suggest that the statue was originally covered in a gypsum layer before the application of complex and diverse recipes of pigment applied as mixtures and in layers to create required hues and shadowing on sculpted features. The palette includes ochres and green earth mixed with small amounts of minium (red lead), realgar and lapis lazuli (ultramarine blue) added to create skin tones, and a vibrant blue-green tunic created from Egyptian blue, bone black, ochres, cinnabar and green earth; the palla and peplos contained ochres, bone black, and orpiment, and mixes of these created the detail of coloured jewellery. Of great interest was the detection of bone black on many features, particularly as a shading agent to enhance sculpted features, such as folds in cloth, providing a more realistic and flowing articulation. This is a revolutionary observation that provides previously unexplored insights into artistic polychromic practice in Antiquity. [ABSTRACT FROM AUTHOR]

In the summer of a.d. 122, Hadrian (a.d. 117–38) visited Britain as part of his first major journey. It is broadly accepted that the construction of Hadrian's Wall was inaugurated on this occasion. Following recent advances in Upper Germany where the limes palisade is now known to have been under construction when Hadrian visited the province, this paper re-examines the various strands of evidence for the early chronology of the Wall. It is argued that work started well before a.d. 122 and that it was in fact the 'fort decision' which resulted from the imperial visit. The revised sequence offers a fresh perspective on several classic Wall problems and prepares the ground for a new understanding of unique features like the milecastles and Vallum.
