We find amongst them many types--the occult leader and the seeress who explains the coming of Christ. We are shown the spiritual development of an artist, a scientist, a philosopher, a historian, a mystic, and a man of the world; and we hear too the scoffing cynicism of Germanus and the materialistic views of Fox. We are led to realize how the characters are connected on the physical as well as the spiritual plane; and we learn also about the nature of elementals and the twin forces of hindrance known as Lucifer and Ahriman; the former of whom may be described as an embodiment of the spiritual impulse to action, an impulse always necessary but often distorted to bring about self-glorification rather than the ambition to do good; the latter as an embodiment of an influence which seeks to materialize everything, thus hindering true spiritual growth and freedom. These two influences are given to man that he may gain free will by having perfect liberty to guide them in the one direction or in the other. With regard to the writing and production of the plays, Doctor Steiner's habit is to write a play whilst the rehearsals are actually in progress, finishing it a few days before the first public performance, and the first play was written and acted in this manner in August, 1910, the second in August, 1911, the third in August, 1912, and the fourth in August, 1913. It was not until then that the complete key to the development of the characters was attainable. The last play explains the progress of the other three, and, following out the hint given in the second play by the account of the previous incarnation in the Middle Ages, traces the characters right back to their earlier incarnation in ancient Egypt. The plays were performed in Munich every summer under the personal direction of the author and were acted by men and women of several nationalities--all students of his teaching. The audiences numbered some two thousand and were composed entirely of his followers. In 1913, owing to the difficulties and expense incurred each year in securing an appropriate theatre, his supporters acquired a plot of ground in Munich, and plans were designed for a theatre of their own, but the Munich authorities after much prevarication and delay finally prohibited its building, exhibiting in their treatment of Rudolf Steiner the same illiberal spirit as they had shown at an earlier date in the case of Richard Wagner. Because of this, and because of the hostility which his writings and lectures had aroused in other parts of Germany, Doctor Steiner was led to set up his theatre in Switzerland at the little village of Dornach--not far from Bâle. Here a theatre is being built in accordance with his own designs and it is hoped that the plays will be performed there regularly as soon as the edifice is complete.
