characters in Murger. Most of acts one and four follow the book, piecing together episodes from various chapters. The final scenes in acts one and four—the scenes with Rodolfo and Mimì—resemble both the play and the book. The story of their meeting closely follows chapter 18 of the book, in which the two lovers living in the garret are not Rodolphe and Mimì at all, but rather Jacques and Francine. The story of Mimì's death in the opera draws from two different chapters in the book, one relating Francine's death and the other relating Mimì's. The published libretto includes a note from the librettists briefly discussing their adaptation. Without mentioning the play directly, they defend their conflation of Francine and Mimì into a single character: "Chi può non confondere nel delicato profilo di una sola donna quelli di Mimì e di Francine?" ("Who cannot confuse in the delicate profile of one woman the personality both of Mimì and of Francine?"). At the time, the book was in the public domain, Murger having died without heirs, but rights to the play were still controlled by Barrière's heirs. Performance history and reception Initial success The world première performance of La bohème took place in Turin on 1 February 1896 at the Teatro Regio and was conducted by the young Arturo Toscanini. The role of Rodolfo was played by Evan Gorga with Cesira Ferrani as Mimi, but Gorga was unable to accommodate the high tessitura and the music had to be transposed down for him. The initial response of the audience at the first performance was subdued and critical responses were polarized. Despite this varied introductory response, the opera quickly became popular throughout Italy and productions were soon mounted by the following companies: The Teatro di San Carlo (14 March 1896, with Elisa Petri as Musetta and Antonio Magini-Coletti as Marcello); The Teatro Comunale di Bologna (4 November 1896, with Amelia Sedelmayer as Musetta and Umberto Beduschi as Rodolfo); The Teatro Costanzi (17 November 1896, with Maria Stuarda Savelli as Mimì, Enrico Giannini-Grifoni as Rodolfo, and Maurizio Bensaude as Marcello); La Scala (15 March 1897, with Angelica Pandolfini as Mimì, Camilla Pasini as Musetta, Fernando De Lucia as Rodolfo, and Edoardo Camera as Marcello); La Fenice (26 December 1897, with Emilia Merolla as Mimì, Maria Martelli as Musetta, Giovanni Apostolu and Franco Mannucci as Rodolfo, and Ferruccio Corradetti as Marcello); Teatro Regio di
