From BBC Devon: The mystery of the three hares:
The next time you're visiting one of Devon's historic churches, take a close look at what's above your head.
If you look carefully you may well spot an ancient symbol depicting three hares joined at the ears.
Three Devon-based researchers have found the motif in 17 churches in the county and are looking for more.
Art historian Sue Andrew, cultural environmentalist Dr Tom Greeves and photographer and film-maker Chris Chapman have been tracking the motif, and so far have found 29 as roof bosses, 19 of which are medieval, in Devon churches. There are more details at the Three Hares Project website, which includes a gallery of the Devon examples.
