This dissertation reconsiders the key importance of violence as an aesthetic, political, and cultural category in Seamus Heaney's poetry and translations. The dissertation begins by asking how the relation between violence, literature, and nationalism might be understood in the Irish postcolonial context. The author details how specific explosions of postcolonial violence as well as broader cultural manifestations and perceptions of violence have motivated and informed some of the key aesthetic developments and major projects in this poet's career. By examining a wide range of representations from his oeuvre, he details Heaney's deft negotiation of the related problems of violence and decolonization through a complex and compelling poetic of violence. Specifically, he examines Heaney's conception and development of the lyric as a field of force, his employment of the pastoral as an anticolonial mode of resistance, and his translations of canonical texts as acts of counterviolence carried out at the level of the vernacular and form. Through close readings of Heaney's verse, translations, prose, and journalism, the author demonstrates how many of his writings can be profitably read as part of an ongoing attempt to intervene textually in a Northern Irish culture of violence. He also argues that Heaney's often conflicted, occasionally uneven, and frequently brilliant attempts to outface violence through writing have necessitated a remarkable degree of experimentation and adaptation at the level of form, language, and genre. By bringing into interactive and critical focus a study of poetics and postcolonial criticism, the author attempts to demonstrate that a particular set of violent conditions and perceptions (which are endemic to postcolonial situations) have, to a remarkable degree, informed Heaney's highly innovative transformations of inherited cultural materials.
