Celtic Harts Crest by cari
I had a heck of a time finding a Celtic version of a stag in my reference books! There were a few in some metalworks, and as well one in the Book of Kells. After figuring out the common characteristics among all the stags, I made my own "leaping stag", which I think comes closest to the style of the Kells stag I had found. The original also contains added touches of gold leaf, which do not appear in the print edition.
