Virgil: Aeneid IV

In Book IV of Virgil's "Aeneid", one of the most studied books of that epic poem, Dido, queen of Carthage, is inflamed by love for Aeneas. The goddesses Juno and Venus plot to unite them, and their 'marriage' is consummated in a cave during a hunt. However, Jupiter sends Mercury to remind Aeneas of his duty, and the hero departs despite Dido's passionate pleas. At the end of the book, Dido commits suicide.
