By taking Brian Friels two plays Translations and Making History as examples, the paper first summarizes Friels imaginative narrative strategy in his history plays, and then points out the significant connection between the playwrights history viewpoints and the cultural politics of Field Day Theatre Company founded in the 1980s. After evaluating Friels ethics in the idea of “crossing boarders”, the paper aims at emphasizing the cultural significance of the construction of new criteria in the evaluation of history borrowing in historical plays.
