The Colossus: "Bundtzen also interprets the poem through a feminist lens. She sees it as an illumination of "woman's psyche as it is shaped by a patriarchal culture." She cites Plath's many allusions - to the Oresteia and Greek tragedy - to suggest that the speaker is conflicted about having to exist in the shadow of a father figure, while remaining desperate for it to speak to her. She is unable to declare her individuality in this context, and yet cannot muster the strength to make a change. From this perspective, the poem offers a more universal critique, rather than merely exploring the author's personal past." - where is this from?
