ABSTRACT This article presents historical and scientific analysis, as well as the conservation treatment of a newly rediscovered Roman wall painting fragment, now in the collection of the Harvard Art Museums. Although the piece has not previously been published, it was among a group of fragments removed from a Roman villa near Boscotrecase in southern Italy, an area that has been key to the study of Roman wall painting and other decoration. Technical imaging confirms the use of painting techniques consistent with other high-quality paintings in the area. Materials analysis revealed a palette consistent with published findings of Roman wall paintings, including abundant use of Egyptian blue and green earth. Of interest was the use of Egyptian blue as an optical brightener in select white passages. Despite the high quality of the painting, no cinnabar was present, and all red passages were achieved using hematite. Multiple different white minerals were identified including calcite, aragonite, and gypsum. The widespread presence of gypsum is unusual and may point to alteration. 相似文献

It has been argued by both educationalists and social researchers that visual methods are particularly appropriate for the
investigation of people’s experiences of the school environment. The current and expected building work taking place in British
schools provides an opportunity for exploration of methods, as well as a need to establish ways to achieve this involvement
of a range of school users, including students. This article describes a consultation that was undertaken in a UK secondary
school as part of a participatory design process centred on the rebuilding of the school. A range of visual methods, based
on photographs and maps, was used to investigate the views of a diverse sample of school users, including students, teachers,
technical and support staff and the wider community. Reported here is the experience of using these tools, considering the
success of different visually-based methods in engaging a broad cross section of the school community and revealing useful
information. Using a range of visual methods allows a complex, but coherent, understanding of the particular school environment
to be constructed and developed. It is further argued that such a range of visual and spatial methods is needed to develop
appropriate understanding. The study, therefore, contributes to knowledge about specific visual research methods, appreciation
of the relationship between tools, and a general methodological understanding of visual methods’ utility for developing understanding
of the learning environment. 相似文献
