This article analyses the creative engagement of the Irish-language poet Ni Dhomhnaill with Helene Cixous's e criture feminine. Ni Dhomhnaill translates Cixousian images and concepts into her texts, returning on several occasions to the concept of l'autre bisexualite ' (the other bisexuality'). Cixous uses this concept to rehabilitate-and celebrate-what she designates as ` the feminine', the alterity within and outside the self. For both writers, this alterity comprehends marginalized cultures as well as femininity. Both bring anti-essentialist convictions to their views of gender and cultural identity, but their respective poetics are born of shared preoccupations with biblical and mythological figures, and narratives often implicated in essentialism. Ni ' Dhomhnaill connects these archetypal figures with the cultural realities of post-colonial Ireland. The author argues that she draws on the works of Cixous to connect the indigenous Irish language and culture with the rehabilitation of femininity. But whereas, in Cixousian texts, 'femininity' eludes concrete definitions and stable meanings, in the works of Ni Dhomhnaill, it often signifies an authentic pre-colonial culture that is ripe for rediscovery in post-colonial Ireland. Ni Dhomhnaill simultaneously celebrates this culture and acknowledges its embeddedness in a Celtic patriarchy that her Cixousian tropes work to undercut.
