This chapter evaluates the status of Seamus Heaney as a postcolonial poet by arguing for a reading of Heaney’s concurrent investment in matters related to colonial politics – a classic postcolonial concern – alongside the burden of aesthetics such that form emerges as sedimented content, and colonial borders yield to a transnational imagination. While rooted in Ireland and a landscape marked by colonialism, Heaney’s brand of transnational poetics is marked by errancy, a mode of wandering and taking flight that discloses alternative horizons for the postcolonial aesthetic and political imaginary. Along with references to other works, this chapter features a close reading of an unpublished poem, 'Errata for BK'.
