The popularity of the opera with the general public spread rapidly, and very soon there was no stage in Germany where "Don Juan" had not acquired permanent possession. According to Sonnleithner's calculation, "Don Giovanni" had been performed 531 times at Vienna at the end of the year 1863; at Prague, Stiepanek asserts that 116 representations took place during the first ten years, and 360 before 1855;[51] at the celebration of the fiftieth anniversary of "Don Giovanni" at Berlin, in 1837, more than 200 performances were calculated to have taken place;[52] similar celebrations took place at Prague[53] and Magdeburg.[54] The opera was first introduced at Paris in 1805, in a fearfully distorted and mangled version, by C. Kalkbrenner; a characteristic instance was the masque terzet, where the words "Courage, vigilance, adresse, défiance, que l'active prudence préside à nos desseins" were sung by three gendarmes. Kalkbrenner also interpolated some of his own music, and, spite of it all, the fabrication pleased for a time.[55] In the year 1811 "Don Giovanni" was first given in its original form by the singers of the Italian opera, and ever since the most distinguished artists have retained Mozart's masterpiece upon this stage in an uninterrupted succession of performances.[56] A French translation of "Don Juan," by Castil-Blaze,[57] was given at Lyons in 1822, at the Odéon in Paris in 1827, and at the Académie de Musique in 1834, admirably cast and brilliantly appointed, besides being more true to the original;[58] a still newer adaptation has been performed at the Théätre Lyrique.[59] In London the great success of "Figaro" had paved the way for "Don Giovanni," which has ever since its {STATISTICS OF PERFORMANCES.} (143) first performance, in April, 1817, occupied a prominent place at the Italian opera of that city. The applause which followed the first Italian representation was so great that the lessee of Covent Garden theatre produced an English version in May of the same year, which was excellently performed, and with considerable success.[60]
