The Birth of Venus

The novel opens in August 1528 at the convent of Santa Vitella, where the elderly Sister Lucrezia has died after a week of howling agony from a supposed breast tumor. A plague outbreak forces the Reverend Mother to override Lucrezia's dying wish that her body remain untouched. When two nuns strip the corpse, the tumor proves to be a pig's bladder filled with animal entrails. Beneath the habit, they find an elaborate painting on Lucrezia's skin: a silver-green serpent curling from shoulder to stomach, its head bearing a man's face with closed eyes and a tongue darting toward her sex.

The narrative shifts to the first-person voice of Alessandra Cecchi, who begins her recollections in 1492 Florence. Alessandra is the younger daughter of Paolo Cecchi, a cloth merchant whose fortune funds a new palazzo with a private chapel. That spring, her father brings home a young orphan painter, raised in a monastery, to fresco the chapel. The household also includes Alessandra's intelligent mother; her betrothed older sister Plautilla; her vain brother Tomaso; her gluttonous brother Luca; and Erila, an enslaved woman of North African origin who serves as Alessandra's closest companion.

Precocious and passionate about drawing, Alessandra is frustrated by the constraints placed on women of her class. She sneaks into the painter's quarters and critiques his work, establishing a volatile dynamic. Over time, during portrait sittings in the chapel, she draws him into conversation about art. His extraordinary skill makes her desperate to learn from him, but he remains withdrawn.

Lorenzo de' Medici, the city's foremost patron, dies that spring, destabilizing Florence. The Dominican friar Girolamo Savonarola gains influence with sermons condemning corruption and prophesying divine punishment. Meanwhile, mutilated bodies begin appearing near Florentine churches, the first in a series of unsolved killings. Alessandra discovers the painter leaving the house at night. Tomaso claims the painter frequents prostitutes, but Alessandra intercepts a dropped sketch of a dissected corpse and realizes his nocturnal excursions involve studying the dead.

Alessandra's parents arrange her marriage to Cristoforo Langella, a cultured, much older art collector and poet. Reasoning that marriage will grant her freedom and protect her from confinement, she agrees. The wedding takes place on November 26, 1494, amid political chaos following the exile of Piero de' Medici, Lorenzo's inept son. Cristoforo shows Alessandra his treasures, including Botticelli's unfinished illustrations for Dante's Divine Comedy. On their wedding night, he confesses he desires men, not women, and the marriage was arranged as cover for his sexuality in the dangerous climate of Savonarola's moral crusade. Worse, Tomaso is his lover, and it was Tomaso who proposed the match, claiming Alessandra wanted freedom more than a husband. Devastated, Alessandra accepts Cristoforo's offer: the run of his house, library, and art in exchange for an heir and discretion.

Savonarola's power surges. His Christmas sermon excludes women from the cathedral, which Alessandra and Erila infiltrate through a side entrance. He imposes strict moral codes and deploys boy militias called Angels to police the streets. Alessandra falls into despair over her loveless marriage. She accidentally cuts herself while sharpening chalk and uses the blood to paint on her naked body before Erila stops her. During her recovery, Cristoforo sends paints, brushes, and prepared panels to a room near her bedroom. Alessandra begins painting and slowly heals.

Months later, she discovers the painter has barricaded himself in the chapel, refusing food for weeks. She forces her way in and finds him emaciated and delusional, convinced God has abandoned him. He has mutilated his palms into stigmata-like wounds and confesses that his nighttime wanderings involved secret anatomy sessions at Santo Spirito hospital, where artists dissected unclaimed corpses to study the body. After the French invasion, the same corpses began appearing mutilated around the city, and the painter became convinced he had participated in something evil. Behind tarpaulins, Alessandra finds his stunning but heretical frescoes: On the ceiling where God should sit, the painter has placed the Devil with Christ and Mary stuffed between his teeth.

Alessandra takes the painter to her house and nurses him. She reads him Dante, coaxes him into drawing, and one night they make love, an act she initiates. Erila insists Alessandra sleep with Cristoforo immediately to establish potential paternity. The painter returns to complete the chapel frescoes, replacing the Devil on the ceiling with a Madonna bearing Alessandra's face.

Alessandra becomes pregnant. During the chapel consecration, the painter allows her to paint a figure of young Santa Caterina directly onto the wall. Tomaso, disfigured by French boils (syphilis), discovers them together and grows suspicious about the pregnancy's timing. Luca, now a brigade commander in Savonarola's boy militia, betrays Tomaso on charges of sodomy. Under torture, Tomaso names the painter, who is arrested. Cristoforo secures the painter's release through political connections, but the painter is banished from Florence. Savonarola's power collapses after a farcical ordeal by fire is extinguished by a thunderstorm, and the friar is arrested.

Alessandra goes into labor in a nearly empty house. Cristoforo confronts her, asking if he is the father. When she honestly answers she does not know, he leaves. Her mother arrives to deliver the baby, a girl. Cristoforo's body is reportedly found murdered, but the corpse belongs to a stranger. Her mother explains that Cristoforo has faked his death and fled with Tomaso, bequeathing his estate to Alessandra. Her mother also reveals that Alessandra was conceived during her own affair with Lorenzo de' Medici at his villa in 1477, explaining Alessandra's intellectual gifts and unconventional nature. Alessandra names her daughter Plautilla, after her sister, who dies in childbirth shortly afterward.

On May 10, 1498, Alessandra leaves Florence with Erila, her daughter, and the Botticelli manuscript as Savonarola burns in the piazza behind her. She enters the convent of Santa Vitella, taking the name Sister Lucrezia. The convent is a thriving community of creative women. Alessandra spends years painting chapel frescoes and raising Plautilla, who shows remarkable artistic talent. Erila gains her freedom and becomes indispensable to the community.

When Plautilla is nearly fourteen, the painter arrives, now confident and transformed by years in Rome. He and Alessandra become lovers again. On their last night, he paints the serpent on her body. When the paint fades, Alessandra has Erila make the image permanent using tattooing techniques learned from the dyers of Santa Croce. She sends Plautilla away with the painter to train in Rome, along with the Botticelli manuscript. They travel to England, and eventually their letters stop.

Church reform strips the convent of its liberties. Alessandra, old and losing her sight, decides to end her life. She enlists Erila to simulate a fatal tumor with a pig's bladder and to bring her poison. She entrusts her manuscript, the very text the reader has been reading, to Erila for delivery to Plautilla. Reflecting on her chapel as mediocre by the age's standards but heartfelt, Alessandra takes comfort in having been part of the great chorus of Renaissance art. The narrative circles back to the prologue: The reader understands that Sister Lucrezia is Alessandra, and the serpent on her body is the permanent record of her passion.
