Tasting the milk of celestial knowledge. Note about the rhetoric of the portrayal of the sacred in Alonso Cano’s painting The Lactation of St. Bernard (1653–1657) from the National Gallery in Prague

This is an attempt of interpretation of a picture that draws from mystical tradition. It is about the comprehension of a topic in a painting by the Spanish artist Alonso Cano (1601–1667, Granada), from the National Gallery in Prague (O 14 690) Lactatio S. Bernardi – presenting the miracle of lactation, in which the Virgin Mary is squirting milk from her breast into the mouth of St. Bernard of Clairvaux (a historically very famous saint and major representative of the Cistercian Order). Traces of iconography lead up to the Coptic Church, where the typology of the milking Virgin was probably first originated (Galacto Trofusa in Greek or Maria lactans in Latin). The starting point is perhaps the portrayal of the virgin goddess Isis milking her son Horus. In many cultures, milk symbolises physical and spiritual food (e.g. the Milky Way evoking the ancient myth about spurted divine milk). On the other hand, milking is also present in the Old Testament as the image of special blessing; it is a symbol of eternal beatitude and wisdom. The dream/vision of her milk is then – apart from the rest – a sign of abundance, fertility, love, and fullness. The lactation of St. Bernard is an allegory of the penetration of the divine science in the soul. Thanks to this act the saint receives God’s guide, which he can then discharge into his writings.
