Is "The Kraken" a sonnet?

Almost. It has fifteen lines instead of the usual fourteen, and Tennyson doesn’t adhere strictly to a Petrarchan or Shakespearean rhyme scheme. However, it clearly references the sonnet tradition — featuring a single sustained subject, a concise argument, and a closing couplet that delivers a strong conclusion. Think of it as Tennyson adapting the form to suit a subject that defies typical classifications.

What does "the latter fire" mean?

It refers to the apocalyptic fire mentioned in Christian scripture — particularly the notion that, at the world's end, fire will engulf everything, even the seas. Tennyson employs this imagery to imbue the Kraken's awakening with cosmic importance: only the actual end of time holds enough power to rouse it.

Why does the Kraken die as soon as it surfaces?

Tennyson doesn't break it down mechanically, and that's intentional. The Kraken is completely from the deep—it is *of* that world, not this one. As soon as it enters the human realm, it no longer exists. There's also a theological interpretation: it emerges at the apocalypse, indicating that the world is ending just as the creature appears.

What are the polypi in the poem?

"Polypi" is an archaic plural for polyp, which refers to creatures resembling octopuses or squids. Tennyson depicts them as vast and numerous, their arms undulating through the water surrounding the slumbering Kraken. They contribute to the feeling of a strange, bustling world on the ocean floor that remains unseen by humans.

What themes does the poem explore?

The main themes are mortality, time, and nature. The Kraken has existed for geological ages, which makes human lifespans seem insignificant in comparison. Its death as it rises to the surface connects it to both mortality and the idea of an apocalypse. Overall, the poem reflects on aspects of the natural world that lie completely outside human grasp or comprehension.

Why did Tennyson write about the Kraken?

Tennyson wrote in the Romantic tradition, which was captivated by the sublime — the notion that nature holds vast and powerful elements that evoke both awe and fear. The Kraken served as an ideal symbol for this: ancient, massive, elusive, and apocalyptic. It also allowed him to delve into concepts of deep time and the unconscious, themes that resonated in the intellectual circles of the early 19th century.

Is the poem optimistic or pessimistic?

Neither cleanly. The Kraken's existence isn’t strictly happy or sad—it just *is*, in a way that renders those labels almost trivial. The ending carries a tragic element (it rises only to die) yet possesses an unsettling grandeur. Tennyson appears to focus more on evoking awe than passing judgment.

The Kraken

Alfred, Lord Tennyson, 1830

Below the thunders of the upper deep ; Far, far beneath in the abysmal sea, His ancient, dreamless, uninvaded sleep The Kraken sleepeth : faintest sunlights flee About his shadowy sides : above him swell Huge sponges of millennial growth and height; And far away into the sickly light, From many a wondrous grot and secret cell Unnumber'd and enormous polypi Winnow with giant arms the slumbering green. There hath he lain for ages and will lie Battening upon huge seaworms in his sleep, Until the latter fire shall heat the deep ; Then once by man and angels to be seen, In roaring he shall rise and on the surface die.

§01Quick summary

What this poem is about

A massive sea creature known as the Kraken lies undisturbed at the ocean's depths, surrounded by bizarre creatures thriving in the darkness. It has rested there for millions of years, feeding on sea worms, and will only emerge once — at the world's end — when it will rise, be witnessed by humans and angels, and then perish.

§03Line by line

Stanza by stanza, with notes

Below the thunders of the upper deep; / Far, far beneath in the abysmal sea,
Editor's note
Tennyson begins by immersing us deep underwater, far below the chaotic sounds of the surface. The phrase "thunders of the upper deep" vividly captures the ocean's surface — noisy and tumultuous from above, yet the Kraken resides even deeper than that. The repetition of "far, far" drives the creature deeper into our imagination before we encounter it.
His ancient, dreamless, uninvaded sleep / The Kraken sleepeth : faintest sunlights flee
Editor's note
Three adjectives pile up before we even learn the creature's name: ancient, dreamless, uninvaded. This sleep isn't peaceful in a cozy way — it’s a complete void. No dreams, no visitors, no light. The choice of the word "flee" when describing sunlight is revealing; even light appears to want to stay away from this place.
About his shadowy sides : above him swell / Huge sponges of millennial growth and height;
Editor's note
The Kraken is so immense and so motionless that massive sponges have developed around it over millions of years. "Millennial" refers to something that has lasted for thousands of years. The creature is practically part of the seabed — a geological formation as much as it is a living being.
And far away into the sickly light, / From many a wondrous grot and secret cell
Editor's note
"Sickly light" refers to the dim, filtered glow that barely penetrates these depths — it's not the vibrant sunlight we expect, but rather something feeble and off. "Grot" means grotto, which is a cave or hollow. The ocean floor is portrayed as a concealed world filled with secret chambers, both amazing and profoundly unsettling.
Unnumber'd and enormous polypi / Winnow with giant arms the slumbering green.
Editor's note
Polypi resemble octopuses or squids. "Winnow" typically refers to the process of sifting grain by tossing it into the air—here, the giant arms are performing a similar action in the water, sifting through the murky green depths. The sight is both mechanical and otherworldly. These creatures are massive, numerous, and completely indifferent.
There hath he lain for ages and will lie / Battening upon huge seaworms in his sleep,
Editor's note
"Battening" refers to feeding greedily. The Kraken feeds without waking — it devours massive prey purely on instinct, in a state of total unconsciousness. Time blurs together into a continuous present: it has always been there, and it will remain there.
Until the latter fire shall heat the deep ; / Then once by man and angels to be seen,
Editor's note
"The latter fire" refers to the apocalypse — the end of the world as described in Christian tradition, when flames engulf everything. Only then will the heat reach the ocean floor and stir the Kraken. Its brief appearance is witnessed by both humans and angels, elevating this event to a cosmic scale, beyond just the earthly realm.
In roaring he shall rise and on the surface die.
Editor's note
The poem concludes with a harsh, compact line. The Kraken rises, roars, and dies — all in one breath. Its whole existence has been spent in sleep and waiting, and its single moment of wakefulness is also its final one. There’s something both awe-inspiring and profoundly melancholic about this. The creature never really experiences life in a way we would understand.

§04Tone & mood

How this poem feels

The tone is slow, heavy, and filled with awe — like standing at the edge of something too vast to fully grasp. Tennyson uses thick, deliberate language, rich with long vowels and weighty adjectives, making the poem feel as if it’s gliding through deep water. There’s no outright fear, but a constant sense of dread and oddness. The ending arrives with a quiet finality that feels almost mournful.

§05Symbols & metaphors

Symbols & metaphors

The Kraken: On the surface, it seems like a mythological sea monster. However, Tennyson uses it to symbolize something much bigger: the unconscious, the ancient, the unknowable. It can also be interpreted as a symbol of apocalyptic power — a force beyond human time that will only reveal itself at the very end of all things.
Sleep: The Kraken's sleep isn't just rest — it's a form of suspended existence, teetering on the edge of death rather than life. In this context, sleep symbolizes the immense spans of time and history that remain beyond human perception, untouched and out of reach.
The deep / the abyss: The ocean floor represents everything beyond human sight and understanding: the unconscious mind, the distant past, and the mysterious forces that shape existence. Light barely penetrates this depth, and the creatures that inhabit it operate under completely different rules.
The latter fire: A direct reference to apocalyptic fire from Christian eschatology, this moment is the only one potent enough to stir the Kraken — the end of time itself. It places the creature's existence within a grand, theological timeline.
Polypi: The countless, massive, unnamed creatures around the Kraken hint at a vast ecosystem of bizarre and monstrous beings that humans never encounter. They embody the vibrant, alien life that exists completely beyond human experience.
Sickly light: Light in this poem feels weak and wrong — it "flees" instead of illuminating. This twisted light represents a world where typical human values and perceptions don't apply. Knowledge and clarity can't reach this place.

§06Historical context

Historical context

Tennyson published "The Kraken" in 1830 in his collection *Poems, Chiefly Lyrical*, which he wrote while he was still a young man at Cambridge. The Kraken is a legendary sea monster from Scandinavian folklore that had been a part of European culture for centuries. It gained renewed attention in 1752 when Erik Pontoppidan, the Bishop of Bergen, described it in detail in his *Natural History of Norway*. By Tennyson's time, the Kraken had become a well-known figure in Romantic-era literature, symbolizing the sublime — the idea that nature holds immense forces beyond human comprehension. The poem takes the form of a sonnet, but Tennyson expands it to fifteen lines and avoids the typical turn, allowing the creature's stillness to dominate the entire piece. It fits neatly within the Romantic tradition of exploring both terror and awe in nature, while also hinting at the Victorian unease about deep time that Darwin's work would soon amplify.
