Prédication de saint Bernardin

This Preaching of Saint Bernardino from 1445 depicts one of the most remarkable phenomena in fifteenth-century Italian urban life—the mass outdoor sermons of the Franciscan friar who could draw thousands of listeners to town squares across central and northern Italy. Bernardino's missions targeted civic pride, luxury, gambling, and faction conflict, urging crowds to burn their vanities and replace family symbols with the IHS monogram. Sano di Pietro witnessed these events firsthand in Siena and became the primary visual documentarian of the Bernardino cult, painting the preacher's ministry with the specificity of eyewitness report. The architectural setting provides rare visual evidence of fifteenth-century Sienese public space.

The open-air preaching scene arranges the vast crowd and the elevated preacher with characteristic Sienese clarity, creating a documentary image of urban religious life rendered with the refinement of panel painting technique.
