Poster for Shaw's Saint Joan
St. Joan is Shaw's version of the events in Shakespeare's Henry VI, Part 1 in which Joan is a major figure, but Shaw takes a more positive view of her even though she is impressively committed to the cause of France in the earlier play.Many of the same characters appear in both plays: the Dauphin, Orléans, Warwick, etc. Picture and some data courtesy of the Yorck Project, under Creative Commons Attribution-Share- Alike License (Wikipedia).
