Familiar to me as a widely used design in Pictish & Celtic art and masonry, the triskelion / triskele is an ancient symbol with a myriad of different interpretations which was actually first seen in very early Maltese & Greek art and symbolism. (thank you wiki!)
I create these by carefully hand folding the individual pages of books. Just folding. I do not cut or carve my books in any way.
Photos shown are of past pieces, most of which have gone to their new forever homes.
Exact colours and final appearances naturally vary from book to book.
