began a lifelong turbulent on again-off again affair with Luisa, that lasted until a few years before his death. In 1897, D'Annunzio was elected to the Chamber of Deputies for a three-year term, where he sat as an independent. By 1910, his daredevil lifestyle had forced him into debt, and he fled to France to escape his creditors. There he collaborated with composer Claude Debussy on a musical play, Le Martyre de saint Sébastien (The Martyrdom of St Sebastian), 1911, written for Ida Rubinstein. The Vatican reacted by placing all of his works in the Index of Forbidden Books. The work was not successful as a play, but it has been recorded in adapted versions several times, notably by Pierre Monteux (in French), Leonard Bernstein (sung in French, acted in English), and Michael Tilson Thomas (in French). In 1912 and 1913, D'Annunzio worked with opera composer Pietro Mascagni, writing the libretto for the opera Parisina, staying sometimes in a house rented by the composer in Bellevue, near Paris. D'Annunzio insisted that the entire, long libretto should be set to music, which eventually meant that the work was too long for audiences of the time, and required the entire last act to be removed. In 1901, D'Annunzio and Ettore Ferrari, the Grand Master of the Grand Orient of Italy, founded the Università Popolare di Milano (Popular University of Milan), located in via Ugo Foscolo. D'Annunzio held the inaugural speech and subsequently became an associated professor and a lecturer in the same institution. D'Annunzio was a Grand Master of the Scottish Rite Great Lodge of Italy which in 1908 had separated from the Grand Orient of Italy. Subsequently, he adhered to the mystic and philosophic movimento known as Martinism, collaborating in Fiume with other 33rd degree Scottish Rite Freemasons and occultists like Alceste De Ambris, Sante Ceccherini and Marco Egidio Allegri. The Masonic initiation of D'Annunzio his testified by the choice of Masonic symbols for the flag of the Regence of Carnaro like the Ouroboros and the seven stars of the Ursa Major. World War I After the start of World War I, D'Annunzio returned to Italy and made public speeches in favor of Italy's entry on the side of the Triple Entente. Since taking a flight with Wilbur Wright in 1908, D'Annunzio had been interested in aviation. With the war beginning he volunteered and achieved further celebrity as a fighter pilot,
