The three plays here presented were the outcome of a period when Björnson's views on many topics were undergoing a drastic revision and he was abandoning much of his previous orthodoxy in many directions. Two of them were written during, and one immediately after, a three years' absence from Norway—years spent almost entirely in southern Europe.
