In her 1964 essay “Notes on ‘Camp,’” Susan Sontag includes Tchaikovsky's Swan Lake (1875–6) in a list that illustrates “random examples” from “the canon of Camp.” Though the ballet has become an integral part of the classical repertory for professional companies from Moscow to New York to Sydney as well as the inspiration for numerous figure skaters (most notoriously in Johnny Weir's outré and rhinestone-bedecked interpretation in 2006), it has, as suggested by Sontag, been creative afflatus for gay underground performers for more than a century. But what are the origins of the swan gone queer? As this article demonstrates, I suggest that one way to trace both the swan's queer genealogy and its continuity lies in the dramatic history and lived performance of the ill-fated Ludwig II (hereafter “Ludwig”) of Bavaria (1845–86)—the Swan King (Fig. 1). Tchaikovsky, after all, had been inspired by the dramatic story of the effete young king (and perhaps titillated by a shared closeted gay desire), who would become a prototype for the ballet's tragic hero, Prince Siegfried. In fact, dance scholar Peter Stoneley suggests that “Swan Lake confirms the virtual impossibility, in Tchaikovsky's [and Ludwig's] era, of accommodating homosexuality within wider society.” Ludwig's desire was expressed through a lens of his same-sex fantasies and their inspired artistic interpretations, most notably taking form in the construction of his neo-Romanesque, fairy-tale castle Neue Burg Hohenschwangau (more commonly known as Neuschwanstein or New Swan on the Rock Castle, though it was not renamed until after Ludwig's death). Ludwig's queer positionality also arises from the theatrical way that he performed a highly aesthetic (though hardly effective) approach to monarchy with his swan-bedecked castle and its environs as a sort of metastage set. In this context, the swan may be read as an example of what Donna Haraway calls “a companion species,” or a personal animal symbol (real or mythical) that represents a variety of feelings that are otherwise difficult to express in the hegemonic context of a given time and place (like homosexuality in Roman Catholic Bavaria in the nineteenth century). Ludwig chose the swan (drawn from family heraldry but primarily envisioned in his own life through storybook-driven fantasy) as a means of alternative expression to that normally available to a man in his position and with his responsibilities, and also as a way to enact his forbidden desires.
