The Miracle of the Ice

Pietro Lorenzetti's Miracle of the Ice, painted around 1332, depicts an episode from the legendary founding of Santa Maria Maggiore in Rome, when miraculous summer snowfall marked the site chosen by the Virgin for her basilica. As one of the two great Lorenzetti brothers who transformed Sienese painting in the early Trecento, Pietro brought a dramatic intensity and spatial inventiveness to narrative scenes that rivaled contemporary Florentine achievements.

Painted in egg tempera on gold ground panel, the scene demonstrates Pietro Lorenzetti's innovative approach to architectural space and crowd composition. His robust figural modeling and strong tonal contrasts reflect the influence of Giotto, while the elegant color harmonies maintain the Sienese tradition of decorative refinement.
