It really was a great joy and privilege to be part of the great Polonsky Project, which was a joint venture between the British Library and the Bibliotèque nationale in Paris to digitise manuscripts which from before the year 1100. They were keen to show how those manuscripts were made, and so it was on two very hot days in the summer of 2017 that Dr Alison Ray, filmer Jan and I spent many hours recording those processes. The films are now on the British Library’s and the Bibliotèque nationale’s websites (the latter being dubbed into French) and sections of the films were also used in the fantastic 2017–2018 Anglo-Saxon Kingdoms exhibition at the British Library.
The first film features the pen used for the writing, which, of course, was usually a quill cut from the feather of a large bird. I always use penknives which have curved blades as the curve rolls over the slight curve in the barrel of a feather to cut the nib tip, whereas a straight blade tends to squash the feather. Indeed, penknives today (the clue is in the name!) still always have a curved blade. Here’s the link. There’s more on quill knives and how to cut a quill on my website on this link.
Ink was usually made from oak galls, although in fact peach, cherry and apricot stones can also be used but give a less dense colour. It’s the tannic acid from the galls reacting to copperas (iron sulphate) that creates a dark liquid, and which needs an adhesive, in this case gum Arabic, to ensure that it adheres to the writing surface. To see the process, click here.
The writing surface was vellum or parchment – calfskin, sheepskin, goatskin or ever deer on occasion. In this clip I explain about the differences between the hair and flesh sides of vellum and also the qualities of other types of skin. More here.
Having cut pieces of skin to size for writing, the page needed to be set out, and often dividers – similar to sets of compasses, but with a point at the end of each leg – were used as it was easier to mark the exact positions of the guidelines in this way. On occasion, the lines would be set out using a ruler and lead point (or similar) and then the positions marked using the tip of a knife (perhaps a penknife). Here the ‘point’ would actually be a triangle shape and this can be seen in some manuscripts. There’s more on setting out a manuscript page here.
Pigments used in illuminations came from animal, vegetable and mineral sources. Perhaps the most famous is ultramarine, as Cennini Cennino called it ‘perfect, beyond all other colours’. A very similar blue, but much cheaper was citramarine. Woad and indigo are from vegetable sources along with madder. And Tyrian purple and carmine came from animals. There’s more on this link, including dragon’s blood!
These pigments have no natural adhesive (apart from saffron interestingly!) and so this needs to be added. Traditional either glair, the egg white or the egg yolk was added. This film clip explains the process, including the equivalent of a hole in one! It can be tricky removing the egg yolk from the egg sac, but when this was being filmed, it worked with the very first egg! Here it is with the knife being withdrawn and the yolk falling out at the bottom. See the whole thing and more here.
And having got everything ready, it was then only the setting out the illumination, laying the gesso, applying gold and then painting bringing everything to life and with wonderful colour. Watch the process here.
It is hoped that these short films will add to the knowledge and understanding of these historical craft processes and ensure that more people understand and appreciate the skills that went in to creating the wonderful manuscripts now in great collections such as those at the British Library and the Bibliotèque nationale.
