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.
A volute is a spiral, scroll-like ornament that forms the basis of the Ionic order, found in the capital of the Ionic column. It was later incorporated into ...
Version of the Triple Spiral symbol (see Image:Triple-Spiral-Symbol.svg) with the area enclosed between the spirals filled in (and mirror-reflected with respect to Image:Triple-Spiral-Symbol.svg). For a less elaborate triskelion symbol, see Image:Triskele-Symbol-spiral.svg or Image:Triskele-Symbol-spiral-five-thirds-turns.svg -- for a more ...
Case 2 is the equiangular spiral, which is the spiral par excellence. This has great historical significance as in Proposition 9 of the Principia Book 1, Newton proves that if a body moves along an equiangular spiral, under the action of a central force, that force must be as the inverse of the cube of the radius (even before his proof, in ...
The spiral is a frequent symbol for spiritual purification, both within Christianity and beyond (one thinks of the spiral as the neo-Platonist symbol for prayer and contemplation, circling around a subject and ascending at the same time, and as a Buddhist symbol for the gradual process on the Path to Enlightenment).
The Archimedean spiral (also known as Archimedes' spiral, the arithmetic spiral) is a spiral named after the 3rd-century BC Greek mathematician Archimedes. The term Archimedean spiral is sometimes used to refer to the more general class of spirals of this type (see below), in contrast to Archimedes' spiral (the specific arithmetic spiral of ...
The Triple Spiral symbol, based on motifs found at the prehistoric site at Newgrange, Ireland, and used as a neo-pagan or Triple Goddess symbol. This version is made up of mathematical Archimedean spirals. For a version with thicker lines, see Image:Triple-Spiral-Symbol-heavystroked.svg.
