Lactatio of Saint Bernard of Clairvaux

The Lactatio of Saint Bernard of Clairvaux depicts one of the most unusual visionary experiences in medieval hagiography: Bernard of Clairvaux, the twelfth-century Cistercian reformer and Doctor of the Church, reportedly experienced a vision in which the Virgin Mary appeared before him and miraculously expressed milk from her breast onto his lips, an act of spiritual nourishment interpreted as a divine confirmation of his devoted Marian piety. The subject became one of the distinctive iconographic innovations of the later medieval and early modern periods, particularly cultivated in regions with strong Cistercian traditions. Crayer's treatment of 1659, now in the Royal Museum of Fine Arts Antwerp, belongs to the fully developed Baroque handling of the subject, where the vision's combination of physical intimacy and supernatural drama provided opportunities for exactly the kind of tender devotional warmth that the Flemish Baroque excelled at. This is among the later works of Crayer's career, painted a decade before his death in 1669.

The subject's combination of physical intimacy and supernatural light required Crayer to handle two distinct registers simultaneously — the earthly space where Bernard kneels and the celestial apparition of the Virgin. The soft, warm light associated with the Virgin's appearance is differentiated from the ambient chapel or interior light, creating a gentle supernatural glow that distinguishes vision from reality.
