Our ancient ancestors had a close relationship with nature and were keenly aware they depended on the elements. The moon and sun were revered by the ancient Celts. Many of the passage and wedge tombs in Ireland are aligned with the rising and setting sun, darkness, and light. The phases of the Moon have been used to represent the life cycle of Women in many cultures. The design shows the ever-changing presence of the moon, its waxing, and waning.
