In more modern times
Today, Pagans continue to celebrate the coming of Spring. They attribute the changes that are going on in the world to an increase in the powers of their God and Goddess (the personifications of the great force that is at work in the world). At the time of Spring Equinox the God and the Goddess are often portrayed as The Green Man and Mother Earth. The Green Man is said to be born of Mother Earth in the depths of winter and to live through the rest of the year until he dies at Samhain.
To celebrate Spring Equinox many Pagans carry out particular rituals. For instance a woman and a man are chosen to act out the roles of Spring God and Goddess, playing out courtship and symbolically planting seeds. Egg races, egg hunts, egg eating and egg painting are also traditional activities at this time of year.
