at Wesendonck's cottage in the last week of April 1857, but Good Friday that year fell on 10 April, when the Wagners were still living at Zeltweg 13 in Zürich. If the prose sketch which Wagner mentions in was accurately dated (and most of Wagner's surviving papers are dated), it could settle the issue once and for all, but unfortunately it has not survived. Wagner did not resume work on Parsifal for eight years, during which time he completed Tristan und Isolde and began Die Meistersinger von Nürnberg. Then, between 27 and 30 August 1865, he took up Parsifal again and made a prose draft of the work; this contains a fairly brief outline of the plot and a considerable amount of detailed commentary on the characters and themes of the drama. But once again the work was dropped and set aside for another eleven and a half years. During this time most of Wagner's creative energy was devoted to the Ring cycle, which was finally completed in 1874 and given its first full performance at Bayreuth in August 1876. Only when this gargantuan task had been accomplished did Wagner find the time to concentrate on Parsifal. By 23 February 1877 he had completed a second and more extensive prose draft of the work, and by 19 April of the same year he had transformed this into a verse libretto (or "poem", as Wagner liked to call his libretti). In September 1877 he began the music by making two complete drafts of the score from beginning to end. The first of these (known in German as the and in English as either the preliminary draft or the first complete draft) was made in pencil on three staves, one for the voices and two for the instruments. The second complete draft (, orchestral draft, short score or particell) was made in ink and on at least three, but sometimes as many as five, staves. This draft was much more detailed than the first and contained a considerable degree of instrumental elaboration. The second draft was begun on 25 September 1877, just a few days after the first; at this point in his career Wagner liked to work on both drafts simultaneously, switching back and forth between the two so as not to allow too much time to elapse between his initial setting of the text and the final elaboration of the
