Haydn's two great oratorios, The Creation and The Seasons (Die Schöpfung and Die Jahreszeiten) stand as monuments—on either side of the year 1800—to the Enlightenment and to the Austrian Enlightenment in particular. This is not to claim that they have no connection with what would often be considered more “progressive”—broadly speaking, romantic—tendencies. However, like Haydn himself, they are works that, if a choice must be made, one would place firmly in the eighteenth century, “long” or otherwise. The age of musical classicism was far from dead by 1800, likewise the “Age of Enlightenment.” It is quite true that one witnesses in both the emergence of distinct national, even “nationalist,” tendencies. Yet these intimately connected “ages” remain essentially cosmopolitan, especially in the sphere of intellectual history and “high” culture. Haydn's oratorios not only draw on Austrian tradition; equally important, they are also shaped by broader influence, especially the earlier English Enlightenment, in which the texts of both works have their origins. The following essay considers the theology of The Creation with reference to this background and, to a certain extent, also attempts the reverse, namely, to consider the Austrian Enlightenment in the light of a work more central to its concerns than might have been expected.
