Before the curtain rises, Pope's prologue tells the audience how to feel, and what those feelings will say about them. Written to introduce Addison's tragedy about the Roman Cato, it argues that the theatre should improve its audience as well as entertain them. Its central claim is that the right kind of tears can be proof of virtue.
The opening four lines build this idea in a single suspended sentence: "To wake the soul… To raise the genius, and to mend the heart; / To make mankind… Live o'er each scene, and be what they behold." The run of infinitives delays the main clause until "For this the tragic Muse first trod the stage," so the sentence feels like a purpose being unfolded. The verbs are all about improvement: wake, raise, mend, make. Tragedy here is a moral workshop. Pope even imagines tyrants who "wonder'd how they wept," which turns the stage into something that overrules a hardened nature.
Pope then sorts emotions into cheap and noble. Addison, he says, avoids "vulgar springs" such as "The hero's glory, or the virgin's love." Love-tears only "our weakness show," while ambition "well deserves its woe." Better are "such tears as patriots shed for dying laws." The phrase "Roman drops from British eyes" compresses the whole project: a British audience is asked to feel an ancient republican grief as its own. "Drops" makes tears sound small and precious, almost like a payment.
Cato himself is idealised. He is "What Plato thought, and godlike Cato was," a figure in whom philosophy has become flesh. Pope's best line about him is "A brave man struggling in the storms of fate, / And greatly falling with a falling state." The repetition of "falling" ties the man to his country, and "greatly" turns defeat into a kind of triumph. Even the detail that Cato gives laws to a "little senate" shrinks the stage around him so that his dignity stands out. The couplet "Who sees him act, but envies every deed? / Who hears him groan, and does not wish to bleed?" uses parallel questions to push the audience toward agreement. Nobody wants to be the person who answers "me."
The longest set piece is the story of Caesar's triumph, where Cato's image is paraded through Rome. Pope loads Caesar with paradox: he is "Ignobly vain and impotently great." Then light drains from the scene: "The pomp was darken'd and the day o'ercast." The crowd weeps, and "The world's great victor pass'd unheeded by." The victor wins the procession but loses the people's attention. The final line, "And honour'd Caesar's less than Cato's sword," lets the weapon stand for a man who would rather die than submit.
The form suits the argument. The poem is written in iambic pentameter heroic couplets, and nearly every couplet closes its thought with a full stop or strong pause. This gives the verse a balanced, courtroom-like confidence: "Tyrants no more their savage nature kept, / And foes to virtue wonder'd how they wept." Rhymes such as *art/heart*, *stage/age* and *laws/cause* link ideas as well as sounds, so that moral concepts seem to belong together naturally.
The final ten lines swing from Rome to the present with the blunt command "Britons, attend." Here the poem becomes sharply national. Pope sets Cato's scorn for "Rome learning arts from Greece" beside the audience's own habit of living on "French translation, and Italian song." The pun in "Dare to have sense yourselves" works because "sense" means both good judgment and feeling, and the audience is asked to show both. The last couplet sets the standard: only plays that "Cato's self had not disdain'd to hear" deserve a British ear.
The poem matters because it states, with unusual clarity, a view of the theatre as a school of public character. It also makes the audience part of the performance. Tears are no longer a private reaction. They become evidence about who you are and whether you deserve to be called free, and that makes the prologue an argument as much as an introduction.
