Solomon’s knot : ウィキペディア英語版 | Solomon's knot
Solomon's knot (Latin: ''sigillum Salomonis'') is the most common name for a traditional decorative motif used since ancient times, and found in many cultures. Despite the name, it is actually classified as a link, and is not a true knot according to the definitions of mathematical knot theory. ==Structure== The Solomon's knot consists of two closed loops, which are doubly interlinked in an alternating (interlaced) manner. In other words, if laid flat, the Solomon's knot is seen to have four crossings where the two loops interweave under and over each other (as opposed to only two crossings in the simpler Hopf link). In most artistic representations, the parts of the loops that alternately cross over and under each other become the sides of a central square, while four loopings extend outward in four directions. The four extending loopings may have oval, square, or triangular endings, or may terminate with free-form shapes such as leaves, lobes, blades, wings etc.
