If we think in terms of postcolonial theory, of poco as a way of reading as much as a body of texts, then there are of course quite a few texts which in their narrative and structure embody the questions of a colonized people struggling to step forth from under domination by a foreign power. Shakespeare's The Tempest is a common text here, as it was in part inspired by the shipwreck of a small colonial flotilla, and the character of Caliban has been seen by many writers and critics as the embodiment of the subjugated or subaltern colonial subject. This view underlies many recent iterations of the Tempest story, such as Aimé Césaire's Une Tempête (A Tempest, 1968), which offers both a radical adaptation and response to Shakespeare's text.
The comparable figure in Beowulf, of course, is Grendel. Like Caliban, Grendel is the lone offspring of a powerful mother, an original inhabitant of the land on which the Shield-Danes built their hall of Heorot. The poem introduces Grendel's hatred of the Danes with the fact that their house was built upon his land. And, although the nominal hero here is the very many who slays Grendel and then his mother, there is room enough for a more sympathetic reading, as was demonstrated by John Gardner in his 1971 novel Grendel. And, with the enormous influence of Seamus Heaney's Irish-ized translation of Beowulf, the position of Ireland as England first colony has been re-framed in implicitly political terms. No less a figure than Professor Seth Lerer, in his essay “On fagne flor: The Postcolonial Beowulf, from Heorot to Heaney,” has taken up this question. Critics may counter, again, that such readings somehow distort the original sense and intent of the poem, but as with any literary text, we need to approach such claims with caution. Any search for the meaning and intent behind Beowulf is beset with difficulties, as it is already a palimpsest of multiple purposes, a warrior poem from a pagan era inscribed within a Christian polemic and rediscovered within the context of linguistic antiquarianism. By whom, and for whom, is such a text today? The postcolonial perspective may well be the answer for our times; the popularity of Heaney's translation will certainly keep this aspect of the poem in readers' minds.
