Giotto’s Circle and Medieval Work in Progress: ‘Illuminated Manuscripts: Art and Science’

The new research presented by Dr Stella Panayotova (Fitzwilliam Museum, Cambridge) at the Research Forum on 24 April 2013 is a perfect summation of the huge advances being made in the field of manuscript studies thanks to exponentially rapid developments in science and technology. Already relatively well-known works of medieval art were shown in a new light, as Dr Panayotova explained how the use of digital reconstruction can debunk certain myths surrounding medieval manuscript production that have been readily spread through literature. Such myths were based on the conclusions of a small selection of academics in an age before such impressive technologies were readily available and have been accepted largely without question by a majority of medievalists. However, the work of Dr Panayotova and the MINIARE project (Manuscript Illumination: Non-Invasive Analysis, Research and Expertise) highlights just how much more research there is to be done in the area.

In collaboration with the Getty, several manuscripts were subject to a variety of intense analytical processes in order to map out more accurately than ever the exact make-up of the manuscripts’ pigmentation. Here, the focus was on the work of Pacino di Bonaguida, a fourteenth century Italian artist whose oeuvre included not only illuminated manuscripts, but also altarpieces. The work for which he is perhaps most well-known, the Chiarito Tabernacle, also went under the microscope.

One of the most useful ways to use this new technology is to distinguish between different artistic hands, not just in manuscripts but in other art objects also. Indeed, it was amazing to see how delicate and subtle some of the stylistic differences between hands were – brushstrokes, for example, can vary greatly in a way that would have otherwise been imperceptible to the naked eye, such as the use of linear, parallel strokes as opposed to cross hatching. It also highlights similarities in the treatment of shadows – particularly noticeable in paintings of flesh and skin – thereby allowing us to draw links that would have perhaps been too anachronistic before. Viewing the manuscripts under UV lights allows for an analysis of the organic make-up of the pigments, what materials have been used and, therefore, which paints were likely to have been mixed in the same workshop or by the same artist and which were done separately. This may initially seem highly technical, but what Dr Panatoyova has shown is that using science in this way can allow us to give a lot more weight to arguments around the provenance of medieval artworks.

It was especially fascinating to hear Dr Panatoyova’s theories on the knowledge and use of colour optic theories in the medieval period, and how our ability to see the subtle techniques utilised by artists gives us much greater insight into how they were thinking about shadow and light. But this is only the beginning – the most exciting thing is speculating on how exactly these technologies might advance our research in the future.
