Corliss Engine

The hours, in a long plunge,
Swirl unconquering
Against this motion clear in steel.
Body of an older birth, like rock
That stands against a sea, this motion breaks
Time’s lesser flow. And here is raised
A symbol of the flight in emptiness
That bears the world and our own selves;
Before such clarity the days fall back; the very days
That drown our lives at last, fall spent
Before the deeper might that builds our blood.

Background and Analysis of This Poem

MacKnight Black's Corliss Engine was published in his 1929 collection Machinery, a title that tells us at once where his poetic imagination had chosen to stand: not in the meadow, not beside the nightingale, but in the engine room. Black is a far less familiar name than many of the poets in this collection, but that obscurity is part of the interest. The Academy of American Poets notes that Harvey MacKnight Black was born in 1896, published in periodicals including The Dial, The Nation, Harper's and Poetry, and died in 1931. His career was brief, but Corliss Engine shows a poet trying to find a language equal to the age of steel, power and industrial motion.

The engine named in the poem was not an imaginary machine. Corliss steam engines, associated with the American engineer George Henry Corliss, became famous for their efficient valve gear and steady industrial power. They were used in factories, mills and power generation, where great flywheels and controlled motion could turn steam into disciplined force. Black does not explain these mechanics in the poem, and he does not need to. What matters is the idea of the machine as something massive, exact and almost elemental. The Corliss engine becomes a symbol of motion that does not simply obey time, but seems to resist and overpower it.

The poem begins with "the hours" plunging and swirling against a "motion clear in steel". That opening sets up one of the poem's deepest tensions: human time against mechanical clarity. Hours usually carry us away. They scatter experience, age the body and drown the details of life. But here, the engine offers another kind of movement, cleaner and more concentrated. Its motion is not the loose drift of ordinary days. It is shaped, repeated and powerful, like a rhythm that has found a body in metal.

Black's language gives the machine a strange antiquity. The engine has a "Body of an older birth, like rock", suggesting that it is not merely modern equipment, but something rooted in deeper forces. That comparison is unexpected and important. We might expect a machine to represent the new, the artificial or the urban. Instead, Black imagines it as rock-like, almost geological. The engine becomes a meeting point between industrial modernity and primal matter. Steel, in this poem, is not opposed to nature so much as formed from a harsher, older nature.

The phrase "a symbol of the flight in emptiness / That bears the world and our own selves" lifts the poem from factory observation into metaphysics. The engine's movement becomes an emblem of existence itself: bodies carried through space, time, labour and mortality by forces larger than conscious will. This is not an easy or cosy vision. Black seems both awed and chastened by the machine. Before its "clarity", the ordinary days "fall back", as if human life, with all its cluttered anxieties, is briefly made smaller by the engine's deeper rhythm.

For modern readers, Corliss Engine is valuable because it reminds us that poetry did not stop at birds, graves, clouds and lost lovers. The industrial world also demanded wonder, and Black answered that demand in a language of steel, blood, motion and time. His poem does not ask us to admire machinery in a shallow way, nor does it simply fear it. Instead, it sees the engine as a concentrated image of power: inhuman, but not meaningless; mechanical, but strangely alive with symbolic force. The Corliss engine stands there in its disciplined motion, while the hours break against it like water against rock.
