x-posted to dragon scribes
One scribe in Insulae Draconis mentioned enjoying Insular and Uncial calligraphy, but was not as confident of doing illumination to match, so I went on a hunt for options for her. After a very productive trawl through the early manuscript pages from Oxford University I have some suggestions, that may help narrow the search for inspiration.
Most cyber scribes have probably looked through this site long before, but I hadn't realised how many early-period Irish books they had. This is in part because there's no index by date, author, subject etc - rather the books are grouped by which college owns them. So you have to scan the lot to find the gems. Argh.
On the plus side, the images are all 600dpi, and stand up well to being enlarged until your screen bleeds.
These are mostly Irish and Old English books, 9-12th c, and cross over between insular hands and early gothic (one of my favourites).
I am not a Celtic art specialist, so I don't know the finer distinctions between Irish, English and Anglo-Norman styles - YMMV.
I did find some simple but elegant large capitals, and some monochrome or 'tinted' paintwork, that might suit 'calligraphy-preferred' scribes like myself.
