After an uncertain beginning, in which each is in love but unaware that it is reciprocated, they begin a correspondance, which takes up much of the rest of the novel. Before writing his first love-letter, Eurialus quotes Virgil in defence of his position, Amor vincit omnia et nos cedamus amori. This page is about Siena, Italy. ...
