Longinus: On the Sublime Explained for English Literature Exams

The most famous name in the history of the sublime may belong to the wrong man. The only early manuscript of On the Sublime, a tenth-century copy now in Paris, names the author as “Dionysius Longinus” in its heading and “Dionysius or Longinus” in its table of contents. For a long time readers took this to mean Cassius Longinus, a third-century rhetorician. Most scholars now place the treatise in the first century CE, about two hundred years before him. That is why you will see the author called “Longinus”, “Pseudo-Longinus” or simply “the author of On the Sublime“.

Here is the part that matters for your exam. Nobody, including the examiner, expects you to settle the authorship question. They expect you to know what the treatise says: the five sources of the sublime, the idea of transport rather than persuasion, and the faults that pass for sublimity. Those three points carry nearly every Longinus question on this site.

Why a lost-and-found Greek treatise keeps turning up in papers

Classical criticism in most syllabi is a short list: Plato, Aristotle, Horace, Longinus. Examiners need four or five questions from that list every cycle, and Longinus is the easiest of the four to frame because his argument comes in numbered parts. Five sources, two of them natural and three acquired. Three or four named faults. A short list of model writers. That structure makes perfect material for “which is the fourth source” and “which of these is ruled out” items.

The second reason is his afterlife. The treatise was almost unknown until it was printed in the sixteenth century, then became a sensation after Boileau’s French translation of 1674. From there it feeds into Burke, Kant and the Romantics. So Longinus also appears in chronology questions, where the sublime is the oldest item on the list.

My advice on priorities: learn chapter 8 (the five sources) word for word, then chapters 1, 3–4 and 7. Know the names Longinus quotes. Skip the long technical discussion of figures and rhythm beyond knowing that it exists.

The text, its survival and the dates worth knowing

Only one work matters here. The dates below trace how it reached English readers, which is where the chronology questions come from.

Ancient dates are estimates, and books differ. If an option says “1st century AD”, treat it as the same answer.

Who wrote it? A short authorship file

This is the module most guides skip, and it is the one that explains the confusing options you meet in papers.

• Cassius Longinus (c. 213–273 CE) was a Greek rhetorician and philosopher who advised Queen Zenobia of Palmyra. For centuries he was taken as the author.
• Dionysius of Halicarnassus, a critic of the first century BCE, is the other name suggested by the “Dionysius or Longinus” heading.
• The modern view is that the author is unknown. The references inside the treatise, including its reply to Caecilius and its closing discussion of why great writing has declined, fit the first century CE better than the third.

In an exam, “Longinus” is always the expected answer to “who wrote On the Sublime“. Use the authorship doubt only if a statement question asks about it directly.

The ideas, one at a time

1. What the sublime is

Longinus opens by defining sublimity as a certain loftiness and excellence in language. It is what has given the greatest poets and prose writers their lasting fame. He is talking about style and its effect, not about mountains and storms. That later meaning comes from Burke and the eighteenth century.

One-line example: a single sentence of Demosthenes, delivered at the right moment, can overpower a whole assembly.

2. Transport, not persuasion

This is the idea examiners love. Ordinary rhetoric persuades: the listener weighs the argument and agrees. The sublime does something else. It “takes him out of himself”. The Greek word usually given is ekstasis. Persuasion is under our control; the sublime is not.

One-line example: you do not decide to be moved by a great line; it happens before you can argue with it.

3. The test of true sublimity

Chapter 7 gives the test: true sublimity is what pleases all and pleases always. When readers of different ages, habits and languages agree on a passage, that agreement is strong evidence. This is the ancestor of every “test of time” argument you will meet later, including Johnson’s.

4. The five sources (chapter 8)

Learn the order. The site’s papers ask for the first, the fourth and the “most important”.

1. Grandeur of thought (the power of forming great conceptions)
2. Vehement and inspired passion
3. Appropriate figures of thought and of speech
4. Noble diction (choice of words, metaphor, elevated language)
5. Dignified and elevated composition (the arrangement of words)

The first two are mainly natural gifts. The last three can be learned through art. Longinus treats the first as the most important, which is where his famous phrase comes from: sublimity is the echo of a great soul. A small mind cannot produce great writing, however good its technique.

5. The faults that imitate the sublime

Chapters 3 and 4 list the ways writers fail while trying to sound grand:

• Bombast (tumidity): swollen language that tries to go beyond the sublime and collapses.
• Puerility: pedantic, over-clever thought that ends in frigidity. The opposite fault to bombast.
• False or misplaced emotion: passion where none is needed, or more than the occasion calls for. Theodorus called it parenthyrsus.
• Frigidity: the cold, flat effect of strained cleverness.

This is why a question can list “immoderate emotion” as something Longinus rules out, even though strong passion is his second source. The difference is control and timing.

6. Imitation of the great writers

Longinus tells writers to imitate and emulate the great classical masters. Ask how Homer, Plato or Demosthenes would have expressed the same thought, and imagine them judging your work. Imitation here means rivalry with the masters, not copying rules.

7. Genius against flawless mediocrity

Towards the end he asks whether a great writer with faults is better than a correct writer who never rises. His answer is the genius, every time. A flawed Homer beats a faultless minor poet. This preference is one reason later critics called his classicism “touched with romance”.

The writers Longinus quotes, and what he says about each

Treat this as a character map of the treatise. Questions often hide Longinus behind one of these names.

Longinus also appears as a wrong option. In the June 2025 UGC NET paper (Q104) he is a distractor in a question about reconciling Plato and Aristotle; the answer is the Neo-Platonists. A chronology item in the Key Terms PYQs (Q51) places the sublime first, before negative capability, dissociation of sensibility and heteroglossia.

FAQ

Who wrote On the Sublime?

The author is unknown. The manuscript says “Dionysius Longinus” or “Dionysius or Longinus”, and the work was long credited to Cassius Longinus of the third century. Most scholars now date it to the first century CE. In exams, the expected answer is Longinus.

What are the five sources of the sublime?

Grandeur of thought, vehement and inspired passion, appropriate figures of thought and speech, noble diction, and dignified and elevated composition. The first two are mainly natural gifts; the last three come from art.

How is Longinus different from Aristotle and Horace?

Aristotle analyses the structure of tragedy and Horace gives practical rules for poets. Longinus asks what makes writing great and finds the answer in the writer’s mind and the reader’s transport, not in rules.

Is the Longinian sublime the same as Burke’s sublime?

No. Longinus writes about elevated language and the great soul behind it. Burke, in 1757, links the sublime to terror, vastness and the natural world.
