There are endless pleasures in Heaney's analysis, but readers should head straight for the poem and then to the prose. (Some will also take advantage of the dual-language edition and do some linguistic teasing out of their own.) The epic's outlines seem simple, depicting Beowulf's three key battles with the scaliest brutes in all of art: Grendel, Grendel's mother (who's in a suitably monstrous snit after her son's dismemberment and death), and then, 50 years later, a gold-hoarding dragon "threatening the night sky / with streamers of fire." Along the way, however, we are treated to flashes back and forward and to a world view in which a thane's allegiance to his lord and to God is absolute. In the first fight, the man from Geatland must travel to Denmark to take on the "shadow-stalker" terrorizing Heorot Hall. Here Beowulf and company set sail:

Men climbed eagerly up the gangplank,
sand churned in the surf, warriors loaded
a cargo of weapons, shining war-gear
in the vessel's hold, then heaved out,
away with a will in their wood-wreathed ship.
Over the waves, with the wind behind her
and foam at her neck, she flew like a bird...

Heaney claims that when he began his translation it all too often seemed "like trying to bring down a megalith with a toy hammer." The poem's challenges are many: its strong four-stress line, heavy alliteration, and profusion of kennings could have been daunting. (The sea is, among other things, "the whale-road," the sun is "the world's candle," and Beowulf's third opponent is a "vile sky-winger." When it came to over-the-top compound phrases, the temptations must have been endless, but for the most part, Heaney smiles, he "called a sword a sword.") Yet there are few signs of effort in the poet's Englishing. Heaney varies his lines with ease, offering up stirring dialogue, action, and description while not stinting on the epic's mix of fate and fear. After Grendel's misbegotten mother comes to call, the king's evocation of her haunted home may strike dread into the hearts of men and beasts, but it's a gift to the reader:

A few miles from here
a frost-stiffened wood waits and keeps watch
above a mere; the overhanging bank
is a maze of tree-roots mirrored in its surface.
At night there, something uncanny happens:
the water burns. And the mere bottom
has never been sounded by the sons of men.
On its bank, the heather-stepper halts:
the hart in flight from pursuing hounds
will turn to face them with firm-set horns
and die in the wood rather than dive
beneath its surface. That is no good place.
