Nemetona is the Celtic Goddess of sacred groves. She was depicted in a shrine at Bath in England. The ram and her consort are later additions from the Roman period. The three figures are the fates, over whom we cannot really hold sway. This figure is therefore a combination of Romano and British images as befitting Bath as a principle Roman city after the invasion. Nemetona holds an apple so she sits in a sacred grove with an apple offering life (and choice) to us as we experience our fates.
The Norns - Norse - govern fate, Urd - what has been, Verdandi - what is, Skuld - what is to come. They spin the threads and weave the tapestry of fate for each person's life. The length of the thread is the life span, even the Gods have their own threads but they are hidden. Everything is predetermined by destiny.
