The West is enamored with rectangles: consider what you are doing right now, reading this on a screen—16:9 if you are at a desk, 9:16 if you are on a phone—which is itself a rectangle inside a rectangle inside a room that is almost certainly a rectangle. Every film you have ever seen unspooled inside a rectangular frame, whether 4:3, 1.85:1, or the grandiose 2.76:1 of Ben-Hur. Every painting you have studied—Caravaggio’s chiaroscuro violence, Hopper’s desolate diners, Basquiat’s crown-studded ferocity—was bounded by a rectangular frame. Your intellectual property, if you have any, is protected by law through a concept that conjures a fenced plot of land: square, bounded, defended at right angles. Even the cell you would be locked in if you committed a crime is a rectangle. Jails are perhaps the most concentrated pressure systems Western civilization has produced, next to boxing rings.

The rectangle is a pressure system—it contains experience, holds it against itself, forces whatever is inside to reckon with its own limits. A cinema audience sits in a dark rectangle watching light move across another rectangle for ninety minutes to three hours, and calls it catharsis. The theater’s proscenium is a rectangle that frames real human bodies, subjects them to duration, extracts transformation. The television—Adorno’s great dystopian instrument of mass pacification—is a rectangle that replaced the fireplace as the organizing center of domestic space. Susan Sontag understood this: photography does not simply record the world, it cuts it, isolates a rectangle of time and says: this. Only this—the isolation doing the arguing that no caption could accomplish.

There are notable exceptions—and what follows here is a truncated list, a sidebar to the broader thesis that will be taken up more fully in an upcoming essay, The Shape of a Poem. Without devolving into shape language across cultures spanning millennia, it is worth pausing to examine the framing devices that either didn’t catch on or operate at different scales, because they stretch the peripheral vision in useful ways. The circle is the rectangle’s oldest rival in painting—the tondo format used by Michelangelo, Raphael, Bronzino, and Botticelli, rooted in Florentine devotional practice, and Murakami’s circular canvases six centuries later, the format removing the rectangle’s hierarchical logic entirely. The lens preserved that circularity longer than the rectangle would like to admit: the magic lantern threw circular projections for two and a half centuries, early photography held it in the vignette and medallion formats, and cinema inherited the circle as residual formal memory through the iris shot, the fisheye lens, the porthole and arch. The future is already dissolving the border: dome projection places the viewer inside the image, virtual reality removes the frame entirely, and the rectangle, which has organized Western visual culture since approximately 600 BCE, will not dissolve into liberation so much as vertigo, which may be exactly the right response to the disappearance of a container that has held perception in the Western tradition for longer than any living tradition can remember.

Literature has fared no differently. The cuneiform tablet was a rectangle of clay. The papyrus scroll traded one rectangular dimension for another—the line of text running left to right across a surface that unspooled in a single direction, the rectangle just reorganized into a different axis. The codex, when it arrived, simply folded the scroll into pages and called it a book—rectangular leaves bound at a rectangular spine, the shape of a page so naturalized that we no longer see it as a choice. The letterforms themselves are rectilinear, the grid of the page organizing text into columns and margins that are, again, rectangles within rectangles.

The sonnet, which is to say the most durable pressure system the Western lyric tradition produced, is—before it is anything else—a rectangle: fourteen lines of roughly equal length, the iambic pentameter line running to a width so consistent that the stanza on the page reads as nearly square, a block of text that the eye receives as a unified shape before it processes a single word. The volta at line nine is not only a rhetorical turn—it is a visible crease in the block, the rectangle folding against itself, the shape enacting the argument, the sonnet’s geometry inseparable from its power.

And what happened to poetry in the centuries after Petrarch is, formally speaking, the slow loosening of that rectangle: indentation as a wedge driven into the left margin, the stepped line pulling the eye rightward and down, the hanging indent, the caesura widening into white space, the fragments of Eliot and the open field of Olson and the shattered syntax of late Celan—the rectangle dissolving, the grid surrendering, the page becoming a field rather than a column. But what that history actually shows is that the experiments remained the exceptions: open any literary journal published this calendar year and count the rectangles. The page is still a rectangle, the poem still, in the majority of cases, a block of left-justified text that would not have looked strange to a monk copying manuscripts in the twelfth century. The tondo and the iris shot and the dome exist; the square screen is still what most people are watching. Poetry discovered the broken line, the field composition, the spatial argument—and then, mostly, went back to the rectangle, because the rectangle is where the pressure accumulates.

And yet the sonnet has always known something the rectangle cannot fully contain on its own—the fourteen lines are a shape under pressure, the geometry a container for something that strains against it. Petrarch wrote 366 of them for a woman named Laura who almost certainly did not know he existed. Shakespeare bent the form to accommodate his Elizabethan vowels and the particular crisis of his middle age. Donne made it theological and erotic simultaneously, which is more difficult than it sounds. Hopkins fractured the meter into sprung rhythm, injecting the Anglo-Saxon stress patterns that the Norman Conquest had suppressed for five centuries. Berryman got drunk and called his sonnets a sequence and addressed them to a woman named Lise. Millay wrote them about sexual freedom and the Village in the twenties and was briefly the most famous poet in America, which tells you everything about what has happened to poetry since.

The villanelle is nineteen lines built around two refrains that return, with gathering weight, five times each before colliding in the final quatrain. Dylan Thomas wrote Do Not Go Gentle into That Good Night in villanelle form, and it has since been recited at more deathbeds than any other poem in English—which means the form itself, the obsessive return, the inability to let go of the same two lines, is doing exactly what grief does. Elizabeth Bishop’s One Art is a villanelle about losing things that builds from lost door keys to lost continents to lost love, each return of the refrain ratcheting the pressure until the final stanza, where she breaks and rewrites the line mid-poem, and you feel the fracture in your chest. The nineteen lines are not a container for the emotion—they enact it structurally, which is the only honest way to hold certain kinds of experience.

The sestina rotates six end-words through thirty-nine lines and a three-line envoi, forcing the language to keep finding new use for the same obsessions. Swinburne’s The Complaint of Lisa is a double sestina—seventy-eight lines—which sounds like a technical exercise until you read it and understand that he was trying to replicate the experience of sustained, unrelieved desire: the same six words cycling endlessly, no resolution available, no way out of the form. Ciaran Carson built a whole book, First Language, out of sestinas about the Troubles, and the form’s compulsive return becomes the structure of trauma, of a violence that cannot be processed, only repeated. Terza rima—Dante’s interlocking ABA BCB CDC chain—generates its own forward momentum from the rhyme scheme, which pulls the reader through Hell without allowing a pause; the form enacts the descent rather than describing it, which is the only way a journey into the underworld can be honestly rendered. When a poet chooses a form, or when a form chooses a poet—and it goes both ways—the choice is an argument about the shape of the experience being held: grief needs a form that returns, desire one that circles, trauma one that cannot resolve, the descent one that cannot stop.

So what happens when the inherited forms prove insufficient? When the experience requires a design that no received container can fully hold? This is where the work becomes genuinely dangerous. The safe response is to abandon form entirely—to write free verse, which is not formless but which distributes its pressures differently, less visibly, in line breaks and white space and the rhythm of breath. The twentieth century chose this option overwhelmingly, and produced Whitman’s heirs in Williams and Ginsberg and Plath’s late work, which is magnificent. But something was lost in the exchange—the pressure that formal constraint generates, the consequence that only sustained containment can produce, the difference between a poem that detonates and one that simply disperses.

The other response—the harder one—is to mutate the form, to keep the container but warp it, to build the house and then take a structural wall out and see what happens to the load. This is what Hallucinations proposes. The primary structure throughout the collection is the ghost sonnet: fourteen lines, the Shakespearean architecture intact, but the rhyme scheme buried. Half-rhymes, slant-rhymes, consonance distributed below the surface rather than announced at the line-ending. The turn is a tonal shift rather than a declared volta. The form holds its pressure without declaring itself, which is formally precise: what it contains could not survive declaration. A ghost sonnet operates the way certain kinds of psychological formation operate—the structure is present, it sets the terms, it will not dissolve—you simply cannot see it until you know to look. Readers feel it before they find it. That gap between sensation and recognition is where the poem lives.

From there, the mutations escalate. A reversed sestina with no envoi—the end-words rotating in the opposite direction, the relief of the concluding triplet withheld. A Double Form Sonnet running two simultaneous rhyme engines in opposite directions, the Petrarchan scheme along the left edge, the Shakespearean along the right, the reader held between two different systems of resolution that never arrive at the same place simultaneously. A Sator Square Sonnet embedding the ancient Latin word-square—SATOR AREPO TENET OPERA ROTAS—into the poem’s architecture, the same five words readable in every direction, creating four quadrants of contained pressure. A Chiastic Helix generating torque rather than linearity, the formal argument twisting around itself the way DNA does, because some experiences cannot be held in a straight line. These are not invented for the sake of invention—formal escalation follows experiential escalation, and the wound determines the bandage. When the burden of the poem requires a design precise enough to hold what no received form could contain, the form must change—a poem about recursive inherited trauma requires a form that enacts recursion, a poem about simultaneous contradictory inheritances requires a form that runs two arguments at once, and the invented structures in this collection arise from those moments of formal necessity, the point at which the existing house is not the right shape for what has to be held inside it.

Which brings us to the question nobody in American literary culture wants to ask directly: who reads formal poetry anymore? Not who should—who does. The numbers are not encouraging. Poetry’s readership has contracted steadily since the mid-twentieth century, and formal poetry’s readership has contracted faster, because formal poetry acquired a reputation—not entirely undeserved—for being the province of academic specialists and high school curricula, a museum artifact maintained by people whose relationship to it is primarily professional. The MFA programs produce technically accomplished work that is read almost exclusively by other MFA graduates. The prizes go to books that will sit unread on the shelves of people who bought them to support poetry in principle, a system in which production and recognition are decoupled from readership in any meaningful sense. This is not a sustainable situation—it is a managed decline.

The cause is not that formal poetry is difficult. Difficulty has never been the problem; readers will follow difficulty anywhere if the difficulty feels necessary and alive. The cause is that formal poetry became safe, became the demonstration of competence rather than the enactment of risk, learned to perform technical mastery without the terror that makes technical mastery matter, so that a sonnet that is merely correct is a sonnet that should not have been written, because following the form earns nothing unless the following produces something that could not exist outside it—a different pressure, a different yield, a consequence the open field cannot generate. Pound’s injunction to make it new was not an instruction to abandon tradition but to stop treating tradition as a museum; Eliot assembled The Waste Land from fragments of the Western tradition—Sanskrit, Dante, Shakespeare, Marvell, the Grail legend, the Thames—and made something that felt like contemporary experience because he understood that fragments are how the twentieth century actually receives its inheritance; Hughes put Crow inside a world of violence and myth and vernacular brutality and the form held all of it; Plath took the confessional lyric and electrified it until it became something other than confession, and in each case the tradition functions not as constraint but as pressure system, the medium through which the contemporary becomes legible.

The TikTok generation—and this is said without condescension, because TikTok’s formal constraints are genuinely interesting—lives inside pressure systems it did not choose. The fifteen-second video is a container. The algorithm is a form with its own turn, its own recursive return. The meme is a found sestina, the same six images cycling through infinite permutations of the same cultural obsessions, a combinatorial structure that mirrors the rotation of fixed elements through constrained positions. The question is whether the mutations of literary form can keep pace with the mutations of experience—whether the structures developed to hold grief, desire, trauma, and inheritance can still register those conditions as they now present themselves, or whether the formal tradition has fallen so far behind the velocity of contemporary experience that the gap is no longer bridgeable. The answer this collection proposes is that it can, not as assertion but as enactment, because these forms—the sonnet, the villanelle, the sestina—are not relics or exercises or puzzles but pressure systems built for the obsessions, griefs, and fixations that have not gone anywhere, waiting to be loaded with contemporary pressure and rebuilt when the experience outgrows the container, because the rectangle can be warped, the load-bearing wall moved, the house made into something that has never existed before and still holds—which is what formal poetry has always done when it was doing its job, and what it will have to keep doing, or it will not survive to be read by anyone at all.
