i cannot find a picture of it on the web, which will make my arguement much weaker, but there is a small twombly drawing from 1965, untitled, that is supposed to be a hyacinth (ie lover of apollo, prettier then the prettiest). it was discussed v. briefly in the essay for his catalog of photos, as vaginal. but it wasn't--it was a asshole, being tighter and less concentric then most vaginal images, of a different colour, and with the title's queer heritage, and the status of twombly as master of freudian anality, it cannot be anything else.

(the floral asshole motif is something that twombly would know well; in the sense of rimbaud:
It breathes, humbly lurking amidst the moss,
Still moist from an amorous inclination which follows the gentle dip
Of the white buttocks down to the edge of its scarlet hem.

or ginsberg:
please master can I lick your groin curled with soft blond fur
please master can I touch my tongue to your rosy asshole

but also the greeks--the rawness and the encompassing power of the drawing reminded me of fermets translation of cattalus 96, with his discussion of a vorcious asshole)

twomby's work is all about disappearing into language, or language disappearing though--and reading this essay with its concluding discussions of marriage--and how this was done after the rberg reationship in the late 50s--maybe the drawing is about (ironically) coming out of the anal self, into the glory of vaginal conquest?
