Giovanni Boccaccio was born, possibly illegitimate, to a Florentine merchant. His father's business connections would send young Giovanni to Naples, where exposure to courtly culture and classical learning shaped his literary imagination and ambitious temperament.

Boccaccio's father sent him to Naples to learn banking with the Bardi company. The young man proved unsuited to commerce but discovered the sophisticated Angevin court, with its troubadour culture, classical scholarship, and beautiful aristocratic women.

Abandoning banking, Boccaccio studied canon law at his father's insistence. Again he proved an indifferent student, but he immersed himself in classical literature and began writing poetry, determined to pursue a literary rather than commercial career.

Boccaccio claimed to have fallen in love with 'Fiammetta,' possibly an illegitimate daughter of King Robert of Naples. Whether real or fictional, she became his literary muse, inspiring early works and representing the idealized love of his youth.

Financial troubles and his father's recall forced Boccaccio back to Florence. The move was unwelcome, but Florence would provide the setting for his greatest work and the friendship with Petrarch that would define his later intellectual life.

The Black Death devastated Florence, killing perhaps half its population including Boccaccio's father and stepmother. This catastrophe provided the frame narrative for The Decameron, with its ten young people fleeing plague to tell stories of love and wit.

Boccaccio met Petrarch, beginning a friendship that would profoundly influence both writers. Boccaccio revered Petrarch as the greater poet and promoted his work, while Petrarch encouraged Boccaccio's classical scholarship and humanist studies.

Boccaccio completed his masterpiece, one hundred tales told over ten days by seven women and three men escaping the plague. The work's frank treatment of sexuality, satire of clergy, and brilliant prose established Italian as a literary language rivaling Latin.

Florence employed Boccaccio as an ambassador, sending him on missions to the papal court and other Italian states. These diplomatic activities provided income and demonstrated his respected position in Florentine society despite controversial writings.

Boccaccio began his great encyclopedic works on classical mythology and famous figures. 'On the Genealogy of the Pagan Gods' compiled classical myths systematically, while 'On Famous Women' pioneered biographical writing about women in Western literature.

A Carthusian monk convinced Boccaccio that he faced damnation for his sensual writings. He considered burning his books and abandoning literature, but Petrarch's counsel restored his confidence, arguing that literature serves moral ends through pleasure.

Boccaccio laboriously copied Dante's Divine Comedy and other works, helping preserve and disseminate the great poet's legacy. His devotion to Dante established the tradition of Florentine vernacular poetry from Dante through Petrarch to himself.

Boccaccio made a final visit to his aging friend Petrarch. The two scholars discussed literature, exchanged books, and parted knowing they might not meet again. Petrarch's death the following year deeply grieved Boccaccio.

Florence appointed Boccaccio to deliver public lectures on Dante's Divine Comedy at the church of Santo Stefano. These lectures, the first public exposition of Dante, established the tradition of Dante commentary that continues today.

Boccaccio died at his ancestral home in Certaldo, having outlived his great friend Petrarch by just over a year. His Decameron had established prose fiction as a major literary form, and his humanist scholarship helped launch the Renaissance.
