The Celts, a prehistoric race or people, practiced a religion called Druidism.
They believed in good and evil spirits. It was believed that evil spirits captured
the sun god and that was why there was winter. Every beginning of Spring, they would
lit up huge bonfires to frighten away the evil spirits into releasing the sun.
The lighting of bonfires are still a part of Easter celebrations in some countries
today such as in Germany and Belgium. Today, bonfires represent the light coming
to the world through Christ.
The candle is also used as a symbol of the light of Christ.
