As Elm Diamond puts it, in an often-cited essay on Brechtianism and feminism that has, I think, interesting applications for discussions of queer theater as well, "Brechtian theory imagines a polyvalence to the body's representation, for the performer's body is also historicized, loaded with its own history and that of the character, and these histories ruffle the smooth edges of representation" (89).
She takes issue, rightly I think, with Svetlana Alpers's rather literalist view of such Dutch painting, stressing its complexity, allusiveness, and intertextual, self-referential polyvalence. A provocative parallel with The Tempest teases, suggesting that play's links with the vanitas theme.

She suggests that it is more useful to compare reading strategies than textual features: "Ultimately, it makes little sense to argue that some kinds of language ate logocentric where others are not; it is rather that language can be read logocentrically or `differentially.' An illustration of this would be the fact that so-called realist art can be made, in practice, to yield just as much polyvalence as experimental art, provided that it is read in a particular way." Yet these alternatives are asymmetrical because "there are ways in which the writer can attempt to foreground polyvalence, inviting a particular kind of reading, and it seems to me that this is what Lawrence does wherever we find the insistent repetition with variation which is such a hallmark of his style" (p.
Polyvalence and openness of the statement without historical necessity and goal-directed development recalls the texts of antiquity--such as the Purana, for example--where one can experience a beguiling confusion of cosmogonic stories and adventures of Vishnu, Shiva, or the goddess Sita, but also an expanse of cosmologies, rites, social or religious laws, calendars, or stories of old customs.
