A number becomes a companion in Hans Ostrom’s “For Four.” The title already treats four as a recipient, as though the poem were addressed to a person. At its heart, the poem is about the private meanings we attach to numbers. Four’s squareness becomes a way of talking about order, family, and the strange comfort of being contained without being diminished.
The opening separates the speaker from “others.” Where they see the shape of four as a sailboat or a tree, the speaker sees “a sentinel in / the snow, a draftee / more lost than zero, / more alone than one.” That is a striking, almost contrary comparison. Zero is already emptiness and one is already singular isolation; to be “more lost” and “more alone” than those suggests four is burdened with awareness, made to stand watch in a cold landscape, conscripted into a role it did not choose. The line breaks sharpen that loneliness: “one” receives its own line, a visual singleness. At the same time, the word “befriended” in the first line sets the emotional key. This is a relationship, not arithmetic.
Then the poem turns inward. “Circular and disorderly, I / love nonetheless angles, geometry.” The speaker confesses to being round and messy, yet devoted to the clean right angles of four. The word “nonetheless” matters: love here is not a perfect match between like and like, but a reaching across difference. That devotion carries a memory. The speaker “spent summers truing / four corners of foundations / with my founding father.” The verb “truing” is precise and physical—it means making something exactly straight or right. “Founding father” is a playful phrase; it points to a literal father who built foundations, and it also echoes a larger, almost mythic sense of origin. Without needing any biographical detail, the poem roots the love of four in remembered labor, in the act of making something square and stable with a parent. Four becomes inherited skill and intimacy.
The final stanza gathers momentum through a list. “Four’s the only number / that romanced me; it’s / the beat, the measure, / the box, the square. / Quarter and quarto, quadrangle / and corner, a / small number always big / enough to house itself.” The word “romanced” turns friendship into courtship, suggesting that numbers can woo through elegance. The list moves from music—“beat” and “measure”—to geometry and books, a quarto being a book size made by folding sheets into four leaves. The alliteration of “quarter,” “quarto,” and “quadrangle” creates a tight, almost boxed-in music, as if the sounds themselves have corners. The final image is the poem’s most resonant: “a small number always big / enough to house itself.” Four is modest but self-sufficient. A square encloses space; four walls make a room; four beats contain a rhythm. The number does not need to expand into infinity to be complete.
The construction mirrors that idea. The poem uses short, free-verse lines with no regular rhyme, but it contains itself through repeated words and sounds. Enjambment keeps the eye moving down the page, yet each stanza is a compact block, like a room. The first stanza has eight lines, the middle five, the last eight, so the poem briefly narrows before opening again, as if turning a corner.
What makes “For Four” significant is how it makes abstraction feel personal. It does not explain mathematics; it gives the number a body, a mood, a family, a romance. Even a digit can hold memory and shape. Four is not just a quantity here; it is a place where the speaker can live.
