Where can I find good images of celtic crosses?
I haven’t read the appropriate Wikipedia pages for a while but they are a good place to start. High crosses and celtic crosses were a particular product of late insular art, as well as stone carvings (see also the elegant and stylish Pictish carved stones) they also occur in dramatic vform in illuminated manuscripts; Lindesfarne and Kells being the best remaining. Someone recently suggested they were not just religious symbols but also navigational aids. The symbol very likely has pre-christian origins in marking the cycle of the year. George Bain wrote the definitive, and charismatic , book on constructinbg celtic art. Sorry for lack of links: not possible with my device!
