He began in prose, identifying himself completely with his hero and writing with joyous enthusiasm. A letter of April 14 to Reinwald deals at length with love and friendship and their relation to poetic creation. All love, we read, is at bottom love of ourselves. We see in the beloved person the sundered elements of our own being, and the soul yearns to perfect itself in the process of reunion. Thus love and friendship are of the nature of poetic imagination,--the waking into life of a pleasing illusion. Wherefore the poet must love his characters. He must not be the painter of his hero, but rather his hero's sweetheart or bosom friend. Then he makes the application to Don Carlos in these words: I must confess to you that in a sense he takes the place of my sweetheart, I carry him in my heart,--_ich schwärme mit ihm durch die Gegend um_.... He shall have the soul of Shakspere's Hamlet, the blood and nerves of Leisewitz's Julius, and his pulse from me. Besides that I shall make it my duty in this play, in my picture of the Inquisition, to avenge outraged mankind ... and pierce to the heart a sort of men whom the dagger of tragedy has hitherto only grazed. But the 'bosom friend' of Don Carlos soon had his thoughts pulled in other directions. In the first place there came, very unexpectedly, a sugary letter from Dalberg. What led him to make fresh overtures to the man whom, a few months before, he had treated so shabbily, is not difficult to make out. He had become convinced that there was after all nothing to be feared from the Duke of Württemberg. Moreover, since the peremptory rejection of 'Fiesco' the Mannheim theater had been doing a very poor business. What more natural than that the shrewd intendant, with an eye to better houses, should bethink him of the pen that had written 'The Robbers'? From Schwan and from Streicher, who had remained in Mannheim, he knew of Schiller's address and occupation. So he wrote him a gracious letter, inquiring after his welfare and expressing particular interest in the new play. It was now Schiller's turn to be foxy. He replied that he was very well, and that as for the play, 'Louise Miller', it was a tragedy with a copious admixture of satirical and comic elements that would probably render it quite unfit for the stage. Dalberg replied that the specified defects were merits,--he would like to see the manuscript. The upshot of the correspondence was that Schiller, who had been negotiating with a Leipzig publisher but had been unable to make an acceptable bargain for the publication of 'Louise Miller', now determined to revise it for the stage and meet the views of Dalberg if possible. So about the middle of April he laid aside 'Don Carlos' and, for the third time in his life, devoted himself to the irksome task of converting a literary drama into a stage-play. On the 3rd of May he wrote to Reinwald:
