The Sermon of St. Bartholomew

Pietro di Giovanni d'Ambrogio's Sermon of Saint Bartholomew, painted around 1435 and now in the Louvre, depicts the apostle preaching in Armenia before his eventual martyrdom by flaying and beheading. The preaching scene allowed the painter to demonstrate his skill in organizing a multi-figure composition around the central orating figure, with a crowd of listeners responding with varied expressions and gestures. Bartholomew was traditionally identified as the apostle who brought Christianity to Armenia and India, and his legend made him one of the more adventurous figures in the apostolic canon. Pietro di Giovanni d'Ambrogio was a Sienese painter working in the tradition of Sassetta and the refined spiritual art of the Sienese school, bringing its characteristic combination of lyrical line, jeweled color, and devotional intensity to narrative panels. This work was likely part of a predella cycle — a horizontal narrative strip beneath an altarpiece — depicting scenes from the life of Bartholomew. The Louvre's collection of Italian primitive panel painting provides a comprehensive context for understanding how Sienese artists of the 1430s navigated the tension between the International Gothic legacy and the new Florentine Renaissance that was transforming Italian art.

The crowd listening to the preaching saint is arranged before an architectural backdrop, rendered in the refined tempera technique and luminous color that characterize Pietro's contribution to Sienese narrative painting.
