How did Petrarch’s poems about Laura change after her death in 1348?

Following the death of Laura in 1348, Petrarch’s poetry underwent a structural and thematic evolution within his Canzoniere. While he continued to explore themes of sorrow and his enduring obsession, he organized his work into two distinct sections: Rime in vita di Laura (poems written during her life) and Rime in morte di Laura (poems written after her death).12

In the latter section, the poems reflect his spiritual growth and a shift in perspective. Rather than focusing solely on his earthly passion, the collection traces his journey from "youthful errors" and worldly attachments toward a final realization that such pleasures are fleeting. The narrative arc moves from his initial love for Laura to a final invocation to the Virgin, illustrating a transition from earthly desire to ultimate trust in God. Additionally, these later poems often describe Laura’s return to him in dreams, serving as a bridge between his past devotion and his evolving spiritual consciousness.21
