Beaujean claims the young Beethoven could have known Mozart's ouverture through Padre Martini in Bologna, who received a copy from Mozart personally and made it available to his pupils. The lyrics of Ode an die Freude (Alle Menschen werden Brüder) is a poem by Friedrich von Schiller (1785/1803). On the other hand, Mozart's principal theme of the Bastien Et Bastienne ouverture slightly resurfaces at the beginning of Beethoven's Third Symphony (Eroica), but that's probably purely coincidence.
