There are many customs and traditions connected to yearly celebrations which are part of Britain’s folklore (民俗). Lughnasadh is a celebration at the beginning of August. A custom connected with it is to make corn dolls with corn from the last of the harvest. The doll is saved until the following spring when it is put back into the earth with new seeds. People believe that the doll contains the spirit of the corn and will bring a good harvest. Christmas too is full of ancient customs. The traditions of lighting a fire and decorating the home with an evergreen have their roots in times long before Christianity. The fire is to keep away evil spirits and fill the home with light and the evergreen is valued because it is a sign that life continued during those cold, dark days.
Not all the origins of ancient traditions are remembered, however. The roots of Morris dancing, for example, are not known. This is a dance in which men (and sometimes women ) dressed in white dance together. Some people think the dance may be from pre-Christmas times, and others say it was introduced into Britain in the late 15th century and that it comes from Moorish dancing. In any case, it is interesting to see that Morris dancing is not a dying tradition. There are Morris dancing groups in places as far away as New Zealand and San Francisco!
Although these customs have been passed down to us from forgotten generations, they themselves have not been forgotten and continue to play a part in our modern lives. Every week groups of individuals regularly meet to sing, play instruments or practice ancient dances and this month people all over Britain shall be preparing their homes for the ancient celebration we now call Christmas, lighting fires and putting up Christian trees, just as their great-great–grandfathers once did.
