 Sometime in the summer of 1854 he hired a copyist to make a fair copy in ink of "Das Rheingold" (using his own unfinished fair copy as a model), but the copyist's work was so full of blunders that Wagner was forced to dismiss him and resume work on his own copy.He worked at it on and off for several months, alternating this work with the ongoing composition of "Die Walküre".By 25 September 1854 the fair copy of "Das Rheingold" was finally completed.
