Three sets of crescents and three ‘lollipops’ make up the pattern. This pattern is a variation on a traditional Triskelion – a three armed pattern exhibiting spiral and/or rotational symmetry. It is ubiquitous in human culture, it can be found at ancient sites dating back thousands of years on everything from standing stones, to temples and even household goods and jewellery. Triskelion means three legs or three-legged and represents the tri-fold nature of deity – Father, Son & Holy Ghost, or Maiden, Mother & Crone – one often finds it in church window tracing designs.
