The Irish dramatist gives a historical and tragic chronicle of the legendary figure of Jean D'Arc in the 15th century, a little village girl who obeying the secret voices of her mind and her heart, left her sheep and decided to raise the siege of Lorraine and free France from the English feudal lords occupying her country. Her reward was to be burnt in fire as heretic by the Inquisition and five centuries later to be canonized as a Saint. The writer admires and justifies the fighting spirit and the heroic sacrifice of the popular girl who escaped her humble position as an oppressed woman. He declares the value of the fighting position against the organized interests and defends woman within a man ruled world. In the drama of the ''Saint'' the writer found a step to preach the ethical and social truths for which he was fighting in his whole life. His aim is to make a strict criticism of the existing pharisaical social institutions, the abhorrent structures of the ecclesiastical and political power and the mechanisms of rehabilitation -after death- of the unfairly lost popular martyrs.
