Sant'Agostino (Madonna of the Pilgrims)

Houses Caravaggio's Madonna of the Pilgrims (1604-06) in the first side chapel — controversial in its day for showing the Virgin Mary as a barefoot working-class woman with visibly dirty soles, leaning casually on a doorframe to receive two ragged kneeling pilgrims with weather-beaten faces. The radical realism and humanity of the painting was both denounced and celebrated. A full visit also takes in Raphael's fresco of the Prophet Isaiah and Jacopo Sansovino's Madonna del Parto, traditionally venerated by women hoping to conceive.
