Few poems are as relentless as Albert Cook's "Sestina I," and the relentlessness is the whole point. It describes a group, a "we," that has been wounded once on a mountain and cannot stop returning to it. The poem's central idea is that defeat does not end when the fall is over. It lives on as fear, as rage that has nowhere to go, and as a compulsion to climb again knowing the result may be the same.
The form does a great deal of the work. A sestina repeats the same six words at the ends of its lines, shifting their order from stanza to stanza, and here those words are rage, wound, mountain, torn, defeat and despair. Almost nothing on this list is neutral. Four of the six are pain in some form, and the other two, rage and mountain, name the emotion that feeds the struggle and the obstacle that provokes it. Because the words keep returning, the poem seems to circle its own injury. Each stanza tries to look at the wound from a new angle, and each time it runs into the same vocabulary. The speakers are trapped inside their six words just as they are trapped inside their history. The final three-line envoi squeezes all six into a closing sentence, and the result is bleak: "the sure end of rage is the rock torn / Eternal wound on our eternal mountain." The word "eternal" appears twice, as if the wound and the mountain have fused.
The poem is also careful about what kind of suffering it means. In the first stanza, the fall is "not delicately torn / On thorns of rose, but boulders of defeat." This quietly rejects a romantic idea of pain, the pretty, poetic wound. Cook wants something heavier and uglier. The second stanza makes a similar move when it contrasts the "sorest wound" with the one "time's unicorn has torn / With golden horn." The unicorn belongs to myth and beauty. What the speakers actually suffered was humiliating: pinned "spreadeagle" on "black stones," with despair rendered as a "blind, giant Mars," a war god without sight or mercy. The wound is made worse by shame, and the poem returns to that word more than once ("our shameful wound," "the shame of wound / And pain").
The sound of the poem matters too. The lines are roughly iambic pentameter, but loosely, with the stumbles and extra syllables of speech under strain, so the meter never settles into comfort. The poem has no rhyme at the line ends, since the repeated end-words take over that job and supply a different kind of echo. Inside the lines, alliteration tightens the pressure, as in "fed the bonfire of our rage" or "blind goggle eyed despair." The phrase "Promethean defeat" adds a mythic layer. Prometheus suffered an eternal punishment for an act of daring, and the allusion suggests that these climbers see their failure as grand as well as painful, which may be part of why they cannot let it go.
What gives the poem its force is the turn in the fifth stanza. After four stanzas of looking back, the speakers do something that is both heroic and a little terrible: they "turn again to climb a sheerer mountain / Bearing a heavier burden." The burden is "the fear of sharper wound," so they carry the memory of the first failure up the second slope. Courage here is not the absence of fear but the decision to climb while afraid, and the poem refuses to promise that the climb will succeed. The sixth stanza even imagines the mind rehearsing its defeat "to empty darkened halls," a haunting image of failure with no audience to hear it.
The poem is significant for how fully it commits to its own pessimism while still honouring persistence. A sestina is a form that cannot escape its repetitions, and Cook turns that limitation into a portrait of anyone who has failed at something and been drawn back to it anyway. The poem offers no consolation, only recognition, and for a reader who has ever stood at the base of their own mountain, that may be enough.
