Maestà of Sant'Agostino

Ambrogio Lorenzetti painted this Maestà for the church of Sant'Agostino in Siena around 1337, contributing to the Sienese tradition of monumental enthroned Madonnas that had been established by Duccio and Simone Martini. The work reflects the Augustinian order's particular devotion to the Virgin and showcases Lorenzetti's innovative approach to spatial depth and naturalistic detail, which distinguished him among his Sienese contemporaries. It remains in its original church setting, a rare survival of Gothic devotional art in situ.

Painted in tempera on panel with a gilded ground, the composition demonstrates Lorenzetti's interest in three-dimensional space through the angled throne and overlapping figures. The Virgin's drapery shows sophisticated modeling with subtle tonal gradations, while the surrounding saints are individualized with careful attention to physiognomy.
