The rare John G. White collection of folklore and music in the Cleveland Public Library furnished songs and chronicles of the time. In this collection beautiful old French music of the XIth, XIIth, and XIIIth centuries was found. The songs were translated and adapted so that they could be sung by children. The action of the mask was made to take place on Christmas Eve, in the year 1255, in the hall of the castle of Count Mathew of Brittany. The mask began with a procession of forty children, in costume, singing this XIVth Century noel:
Lead us, Lord, where He doth lie this night!
There is a Child of Mary born!
Salvation hath He brought to us,
Whom we should worship night and morn.
Lead us, Lord, a star now shineth bright!
In Bethlehem it so befell
That in a stable born He was
Pray Him for grace to serve Him well.
Show us, Lord, where angel wings are light!
