Performing Irishness analyses the presence and impact of Irish drama in Galicia, a minorised cultural context where Ireland has historically been viewed as a recognisable, often inspirational, «other». Through her exploration of the ways in which translation choices interweave with theatre practice, the author reveals context and on-the-spot decisions as crucial elements in the adaptation and staging of the plays. This study traces the multiplicity of factors that determined the plays' path from one culture to the other by means of interviews with theatre practitioners and a wealth of unpublished documents around the translation and production processes, resulting from extensive archival research. The voices behind the scenes provide us with a viewpoint that goes beyond the texts to generate a pluridimensional map of how Irish drama has travelled not only to Galicia but also to – and through – other Iberian stages.
