So che annunci l’inverno: che fra breve
quella foglia cadrà, fatta colore
della ruggine, e al fango andrà commista,
ma le radici nutrirà del tronco
per rispuntar dai rami a primavera.

Vorrei, pioggia d’autunno, esser foglia,
abbandonarmi al tuo scrosciare, certa
che non morrò, che non morrò, che solo
muterò volto sin che avrà la terra
le sue stagioni, e un albero avrà fronde.
