As it was, deeper instincts of his nature asserted themselves as he proceeded with his work, and Goetz is overshadowed by other characters in the drama in whom the poet himself, by his own admission, came to find a more congenial interest. The play exists in three forms--the first draft being recast for publication in 1773, which second version was adapted for the Weimar theatre in collaboration with Schiller in 1804. It is generally admitted that in its first form we have the fullest manifestation of its author's genius, and equally the fullest expression of the original inspiration that led to its production. Like Shakespeare he had a book for his text--the Memoirs of Gottfried, written by himself; and like Shakespeare he took large liberties with his original--no fewer than six characters in the play, two of whom are of the first importance, being of Goethe's own invention. The plot may be briefly told. Adelbert von Weislingen, a Knight of the Empire, had been the early friend of Gottfried, but under the influence of the Bishop of Bamberg and others he had taken a line which led him into direct conflict with Gottfried. While the latter, identifying himself with the lesser German nobles, was for supporting the power of the Emperor, Weislingen had identified himself with the princes whose object was to cripple it. Gottfried seizes Weislingen while on his way to the Bishop of Bamberg, and bears him off to his castle at Jaxthausen. The contrasted characters of the two chief personages in the play are now brought before us--Gottfried the rough soldier, honest, resolute, and Weislingen, more of a courtier than a soldier, weak and unstable. Overborne by the stronger nature of Gottfried, Weislingen agrees to break his alliance with the Bishop, and, as a pledge for his future conduct, betroths himself to Gottfried's sister Marie, who, weakly devout, is a counterpart to Gottfried's wife Elizabeth, who is depicted as a Spartan mother.[104] To square accounts with the Bishop, Weislingen finds it necessary to proceed to Bamberg, and the second act tells the tale of his second apostacy. At Bamberg he comes under the spell of an enchantress in the shape of a beautiful woman, Adelheid von Walldorf, a widow, whose physical charms are represented as irresistible. Weislingen becomes her creature, forswears his bond with Gottfried, and rejoins the ranks of his enemies--news which Gottfried is reluctantly brought to credit. In the third act we find Gottfried in a coil of troubles. He has robbed a band of merchants on their way from the Frankfort Fair, and, at the prompting of Weislingen, the Emperor puts him under the ban of the Empire, and dispatches an armed force against him. Beaten in the field and besieged in his own castle, he is at length forced to surrender. In the fourth act he is a prisoner in Heilbronn, but is rescued by Franz von Sickingen, a knight of the same stamp and with the same political sympathies as himself.
