It is really not difficult to understand – even for humanists.This trope refers to wielding two weapons at once. It has now been uploaded to youtube and anyone interested in this important though esoteric technique and its possibilities can get a feeling for what it can accomplish. Luckily the presentation was recorded on video. But he is also scheduled to give a lecture at the upcoming Festival for British Archaeology on “Shining Light on Medieval Illuminations: Pigments through the Ages”, where he will explain this rather complicated technology to mere mortal archaeologists and medievalists. Professor Andrew Beeby will continue to present his research in scientific contexts in the near future. For instance a group in Portugal has worked to study Medieval Cistercian 12–13th century manuscripts: Santa Maria de Alcobaça, Portugal, while a third group in Belgium has experimented with using a transportable Raman spectrometer directly on location in the library. the changes in pigment use arising from the Norman conquest.Įlsewhere in Europe other groups of chemists are working on other medieval manuscripts. as book production moved from the monastic to the secular, and of societal change, e.g. The changes in pigment choice and use reflect changes in technology transfer, e.g.

By studying books of well-established provenance and time and place of origin he is currently building a map of pigment use, creating a valuable resource for conservators and historians. Interestingly, some of its first uses were in fact to identify colours in Medieval illuminated manuscripts.Īt Durham Andrew Beeby and his colleagues are currently studying the pigments used in manuscripts produced in the British Isles and northern Europe between the 7 th and 15 th centuries. Naturally, the technique has been both refined and optimized since its first discovery by the Indian physicist, Chandrasekhara Venkata Raman, who was honoured with a Nobel Prize 1930 for his discovery. The Raman spectrum is the pattern of this change in wavelength and provides a unique fingerprint of the pigments.

The scattered light contains a small fraction of light where the wavelength, corresponding to the colour, has changed. Applying this, the sample is illuminated with a single colour of light produced by a laser, and the light scattered from the sample is collected and analysed using a spectrometer. One such technique is Raman spectroscopy. The challenge is to be able to identify materials on a delicate sheet of parchment, typically a folio of a bound manuscript that does not open readily, without contact, sampling or causing any damage. Ideally the technique should give an unequivocal identification of pigments with high spatial resolution and selectivity. Identifying the materials used in medieval illuminated manuscripts gives us an insight into the techniques and skills of the scribes and illuminators, as well as the occasionally complex trade routes of the times. Raman spectroscopy makes it possible without sampling Identifying pigments in medieval manuscripts gives an insight into the technical expertise of artists and sometimes trade-routes.
