Italian Baroque (Barocco) is the stylistic period of Italian history and art from the late sixteenth to the early eighteenth century, born from the Counter-Reformation. As the Catholic Church answered the Protestant Reformation, new religious orders - Jesuits, Oratorians, Barnabites, Theatines - filled Rome with churches (323 by 1725), and art became an instrument of persuasion: spaces of expansive beauty designed to overwhelm and secure the loyalty of congregations. Il Gesù, designed by Vignola, set the prototype with its broad nave and ring-lit dome; Carlo Maderno extended St. Peter's into the Latin cross that became Rome's image; and Bernini fused sculpture and architecture in the great baldacchino (1624-33) and churches like Sant'Andrea al Quirinale. Inside, quadratura painting - most famously Pietro da Cortona's Barberini ceiling - dissolves the vault into open sky, while stucco ornament, curved geometry, and grand proportions turn rooms into theater.
