How did Ovid use elegiac couplets in his poetry?

Ovid utilized the elegiac couplet—a verse form consisting of a hexameter line followed by a pentameter line—as his primary medium for most of his poetic works, with the notable exception of the Metamorphoses.123

Rather than using the form to express deep personal passion, Ovid employed it to entertain, utilizing a style characterized by neat wit, parallelism, and a regular flow. He carried the couplet to its logical extreme, refining the technical facility of his predecessors to achieve remarkable smoothness, fluency, and balance.24

His application of the form included:
* Erotic Poetry: In works like the Amores and Ars amatoria, he used the couplet for the witty and rhetorical exploitation of erotic commonplaces, often adopting a persona to satirize social manners.23
* Dramatic Monologues: In the Heroides, he adapted the couplet to create letters from legendary figures, utilizing his rhetorical training for character drawing.3
* National and Personal Themes: He employed the form for the Fasti, an account of Roman religious festivals, as well as for his later introspective works written in exile, such as the Tristia and Epistulae ex Ponto.3
