Bridget of Sweden (c. 1303 – 23 July 1373) was a mystic and saint, and founder of the Bridgettines nuns and monks after the death of her husband of twenty years.  

At the age of ten, Bridget had a vision of Jesus hanging upon the cross. When she asked who had treated him like this, he answered: 

They who despise me, and spurn my love for them.

She was so impressed that from that moment the Passion of Christ became the center of her spiritual life.

Her visions of the Nativity of Jesus had a great influence on depictions of the Nativity of Jesus in art. Shortly before her death, she described a vision which included the infant Jesus as lying on the ground, and emitting light himself, and describes the Virgin as blond-haired.  The Virgin kneels to pray to her child, to be joined by Saint Joseph, and this (technically known as the "Adoration of the Child") becomes one of the most common depictions in the fifteenth century, largely replacing the reclining Virgin in the West.

Pope Benedict XVI spoke of Bridget in a general audience on 27 October 2010, saying that the value of Saint Bridget's Revelations, sometimes the object of doubt, was specified by Pope John Paul II in the letter Spes Aedificandi: "Yet there is no doubt that the Church," wrote my beloved predecessor, "which recognized Bridget's holiness without ever pronouncing on her individual revelations, has accepted the overall authenticity of her interior experience."

A depiction of the Nativity of Christ showing the newborn Child upon the ground, in the centre-foreground, supported by bundles of hay placed under His head with the kneeling figure of the Virgin in adoration before him. Behind the Virgin, to the right, are the kneeling figures of a shepherd and a nun, Saint Bridget. To the right is an unusual stone formation and rocky outcrop beyond. To the left of the Child is the elderly seated figure of Joseph with a staff in his hand; standing behind him, with hands clasped in worship, is a young shepherd in ragged garments.

In the centre of the composition, beyond the figure group, is a manger and a stable with a donkey and an ox. The background is filled with a landscape scene, with a castle on the left built upon a hill, which descends into a sea in the centre.
