The commonly-used diagram for the Borromean rings consists of three equal circles centered at the points of an equilateral triangle, close enough together that their interiors have a common intersection (such as in a Venn diagram or the three circles used to define the Reuleaux triangle).
The symbol is also sometimes used by Wiccans, White Witches, and some New Agers to symbolise the Triple Goddess, or as a protective symbol. [ 7 ] In the 1998–2006 American fantasy drama Charmed , that ran on the now-defunct The WB network, the triquetra was prominently used as a symbol on the Halliwells' Book of Shadows , the book of spells ...
5,000 year-old triskelion on an orthostat at Newgrange. The triple spiral symbol, or three-spiral volute, appears in many early cultures: the first appeared in Malta (4400–3600 BCE); the second in the astronomical calendar of the megalithic tomb of Newgrange in Ireland built around 3200 BCE; [13] as well as on Mycenaean vessels.
Arcs of the same three circles can also be used to form the triquetra symbol, and the Reuleaux triangle. [3] In Christian art, some aureolas are in the shape of a vertically oriented vesica piscis, and the seals of ecclesiastical organizations can be enclosed within a vertically oriented vesica piscis (instead of the more usual circular ...
Tomoe (巴, also written 鞆絵), [a] commonly translated as "comma", [2] [3] is a comma-like swirl symbol used in Japanese mon (roughly equivalent to a heraldic badge or charge in European heraldry). It closely resembles the usual form of a magatama. The tomoe appears in many designs with various uses.
The symbol features three hares or rabbits chasing each other in a circle. Like the triskelion, [8] the triquetra, and their antecedents (e.g., the triple spiral), the symbol of the three hares has a threefold rotational symmetry. Each of the ears is shared by two hares, so that only three ears are shown.
Expanding sets have 1, 7, 19, 37, 61, 91, 127, etc. circles, and continuing ever larger hexagonal rings of circles. The number of circles is n 3-(n-1) 3 =3n 2-3n+1=3n(n-1)+1. These overlapping circles can also be seen as a projection of an n-unit cube of spheres in 3-dimensional space, viewed on the diagonal axis. There are more spheres than ...
