This magnificent manuscript is undoubtedly one of the most important documents, not only of Stravinsky's oeuvre, but of the entire holdings of the Paul Sacher Foundation. The expressive calligraphy, for which the composer had a fine talent, distinguishes the autograph score in a very special way. Abounding in corrections as well as conducting and publication markings, this manuscript initiated a long process of revision that lasted for decades as the work was extensively edited for publication from 1922 onwards. The edition allows a wider readership to see Stravinsky's Rite in its original forms for the first time, thereby providing an opportunity to further engage with this seminal work of art.
