Celtic Knots

Celtic knots are a variety of (mostly endless) knots and stylized graphical representations of knots used for decoration, adopted by the ancient Celts. Though Celtic knots were being created in Polytheistic Celtic times, these knots are most known for their adaptation for use in the ornamentation of Christian monuments and manuscripts like the 8th century Book of Kells.
