Celtic Knot?

Celtic knots (Irish: snaidhm Cheilteach, Welsh: cwlwm Celtaidd, Cornish: kolm Keltek, Scottish Gaelic: snaidhm Ceilteach) are a variety of knots and stylized graphical representations of knots used for decoration, used extensively in the Celtic and Northumbrian styles of Insular art. These knots are most known for their adaptation for use in the ornamentation of Christian monuments and manuscripts, such as the 8th-century St. Teilo Gospels, the Book of Kells and the Lindisfarne Gospels. Most are endless knots, and many are varieties of basket weave knots.
