The central theme in the Canzoniere is Petrarch's
courtly love for
Laura, with whom he reportedly fell in love at first sight on 6 April 1327 and who died on that date in 1348. The poems however are so sparing of facts that Petrarch had to write his friend
Giacomo Colonna to assert her existence against a charge that she was a fictional creation. The most evident purpose of the Canzoniere is to praise Laura, yet questions concerning the virtue of love in relation to the Christian religion and desire are always present.
Antithesis are also key to the sequence and in one sense represent Petrarch's search for balance; these would later be exploited by Petrarchists in Europe but represent only one aspect of the Rimes. This leads on to the essential
paradox of Petrarchan love, where love is desired yet painful: fluctuation between states is a means of expressing this instability. The changing mind of man and the passing of time are also central themes, as is the consideration of the art of poetic creation itself. Some other themes are desire, isolation, unrequited love, and vanity of youth. In any case, it would be improper to see
Canzoniere as uniquely inspired by love for Laura. Other themes are important: religion, poetry, politics, time, glory. The love theme itself should be considered as the nucleus around which Petrarch develops his deep psychological analysis: thanks to his poems inspired by Laura (
laurus is the symbol for poetry) the poet aspires to reach glory, which in turn can fight the all-destroying power of time. Even glory, however, cannot guarantee real eternity, because in Christianity, only faith in Jesus Christ can guarantee it. ==Influences on the
