Disputation over the Immaculate Conception

Girolamo Genga's Disputation over the Immaculate Conception, dated 1515 and now at the Pinacoteca di Brera, is a theologically sophisticated altarpiece that engages with one of the most contentious doctrinal debates in late medieval and early modern Catholicism. The Immaculate Conception — the doctrine that the Virgin Mary was conceived without original sin — was championed by the Franciscan Order and contested by the Dominicans, generating centuries of theological dispute before its eventual definition as dogma in 1854. Paintings depicting the Disputation typically supported the Franciscan position, displaying theological learning and devotional commitment simultaneously. Genga, a Sienese painter and architect who worked for Guidubaldo da Montefeltro in Urbino, brought considerable sophistication to this demanding subject. The Brera's holding makes it accessible as a document of the important intersection of theology and visual argument in the early sixteenth century.

The composition must simultaneously represent the heavenly realm of the Immaculate Virgin and the earthly theological dispute below creating a two-zone vertical structure. Genga's figure style shows the influence of Raphael and Perugino in its graceful idealised treatment of the celestial figures. The debating figures below are rendered with expressive differentiation. Colour is carefully balanced between the celestial and terrestrial zones.
