Canticle

The story opens in 1299 Brugge, where a young woman named Aleys is led to a stake to be burned as a heretic. The crowd, however, chants Sint! (Saint!), suggesting they view her as holy. In 1295 Damme, thirteen-year-old Aleys is a solitary, sensitive girl who shares a close bond with her mother over an illuminated Latin prayer book, or psalter. Her mother, who is illiterate, tells Aleys stories of the saints from its pictures. When her mother, heavily pregnant, goes into a difficult labor, Aleys prays desperately for her survival. The labor is fatal for both mother and the infant, leaving Aleys and her family devastated.

A year later, Aleys's father, a draper, hires a tutor to teach his children to read and write Dutch for the family business. Aleys excels but longs to read the psalter to feel close to her mother. Her father gives her the book, and she begins teaching herself Latin. While delivering wool with her father, she meets Finn, a dyer's son who speaks Latin but cannot read it. They begin meeting in secret; she teaches him to read, and he teaches her the language's meaning. Their friendship blossoms into a romance as they study the Song of Songs, but Aleys is left heartbroken when Finn announces he is joining a monastery.

After a powerful vision in which an angel tells her to Seek, Aleys's life takes another dramatic turn. A moth infestation ruins the family's wool business, leaving them financially desperate. To save them, Aleys's father agrees to marry her to Pieter Mertens, the powerful head of the drapers' guild, in exchange for a valuable license to sell in the city's cloth hall. Feeling betrayed, Aleys resolves to escape the marriage. She seeks out Friar Lukas, the leader of the Franciscan preachers in Brugge, who has been praying for a devout woman to help him establish a female Franciscan order. Impressed by her faith, Lukas agrees to help her.

On the eve of her wedding, Aleys flees to a church where Lukas performs a secret initiation, cutting her hair and giving her a brown robe. The next morning, her father publicly disowns her. Unsure how to integrate a woman into his order, Lukas places Aleys in the local begijnhof, a community of lay religious women, on a two-month probation. She must recruit new sisters for the Franciscan order by Midsummer. At the begijnhof, Aleys meets the wise magistra, Sophia Vermeulen, and the stern Sister Katrijn. Aleys is shocked to learn the beguines secretly read scripture translated into Dutch, a practice forbidden by the Church. Meanwhile, the Bishop of Tournai, Jan Smet, who is Lukas's brother, tasks his spy, Willems, with finding and stopping the translator.

Aleys fails to recruit any beguines, as they are content with their lives of work and communal worship. Working at the Sint-Janshospitaal with the devout beguine Ida, Aleys's initial fear gives way to a deep admiration for the beguines' practical faith. During a Midsummer festival where the beguines sing the Canticle in Dutch, Aleys realizes she has misjudged them. She soon discovers that Katrijn is the secret translator. While praying over a dying boy in the hospital, Aleys has a vision, and the boy is miraculously healed. News of the event spreads, and the people of Brugge begin to hail her as a saint. The gift is inconsistent, leaving Aleys exhausted and feeling like a fraud, though Lukas orders her to believe in her own holiness.

The Bishop decides to exploit Aleys's fame for political gain by staging a public demonstration of her powers. As the event begins, news arrives that Sophia has suffered a stroke. The Bishop forces Aleys to continue with the staged miracles, threatening to arrest her and Sophia for heresy if she refuses. After the successful demonstration, Aleys rushes back to the begijnhof, but Sophia dies. A grief-stricken Katrijn banishes Aleys from the community. Outside, a frenzied crowd of believers mobs Aleys, tearing at her robe for relics until she falls from a bridge, losing consciousness in the water. Lukas rescues her, but Katrijn, now the magistra, refuses them entry.

To control the situation and separate Aleys from his increasingly obsessed brother, the Bishop has her enclosed for life as an anchoress in a cell attached to the Sint-Salvator cathedral. Seeking solitude, Aleys agrees and is sealed inside after a ceremony conducted like a funeral Mass. She adapts to her new life of prayer, attended by her maid, Marte, and experiences powerful, ecstatic visions. She teaches Marte to read, and Marte begins writing her own radical interpretations of scripture. After a vision of the Virgin Mary, the divine presence abandons Aleys, plunging her into a spiritual crisis.

Lukas, her confessor, becomes increasingly jealous and tormented by his own spiritual emptiness. Believing a sacred union with Aleys is his path to God, he breaks into her cell on Midsummer Eve and attacks her. Realizing she must save herself, Aleys stabs him with a small knife and flees the anchorhold, breaking her vow of enclosure and ensuring her excommunication.

Aleys finds refuge back at the begijnhof, where a changed Katrijn and a loyal Marte take her in. The Bishop, his plans ruined, decides to try Aleys for heresy. He uses Marte's writings as evidence, intending to destroy the beguines in the process. During the trial before a panel of papal inquisitors, Aleys falsely confesses to writing the heretical texts to protect Marte and the beguines. She refuses to recant her beliefs and is excommunicated, with her final punishment to be decided at nightfall.

In her jail cell, Finn visits and begs her to recant so they can escape together, but she refuses, choosing to protect the beguines and remain true to her faith. The next morning, she is led to the stake in the market square. On her walk, she has a final vision, seeing the faces of holy women from the past and future in the crowd. As the pyre, piled with her supposed heresies, is lit, the beguines form a circle around it, holding blank parchment in a silent vigil. Accounts of her death conflict; the Bishop sees her burn horribly, while the papal legate witnesses a glorious whirlwind of light from which no remains are found. Years later, a blind beguine, implied to be a surviving Aleys, lives secretly in the begijnhof, cared for by Sister Marte, who continues to write, preserving a legacy of female spirituality.
