Purgatorio 18.19–21
Virgil to Dante, explaining how love begins
L’animo, ch’è creato ad amar presto,
ad ogne cosa è mobile che piace,
tosto che dal piacere in atto è desto.
The mind, which is created ready to love,
is mobile toward every thing that pleases,
as soon as by pleasure it is awakened into act.
