Why is The Ecstasy of St. Teresa considered a masterpiece of Baroque religious sculpture?

The Ecstasy of St. Teresa (1645–52) is considered a masterpiece of Baroque religious sculpture because it exemplifies Gian Lorenzo Bernini’s ability to synthesize architecture, painting, and sculpture into a unified, multisensory experience that overwhelms the viewer’s intellect.1

Located in the Cornaro Chapel of Santa Maria della Vittoria, the work is designed with theatrical precision. Bernini utilized a proscenium-like arch to frame the central niche, while incorporating marble figures of the Cornaro family in side "opera boxes" to observe the scene. The composition achieves a profound illusion of reality through:12

• Dramatic Lighting: A hidden window provides light from above and behind, enhancing the mystical atmosphere.2
• Textural Mastery: Bernini’s signature ability to transform stone into varied, lifelike textures—such as flesh, hair, and fluttering drapery—makes the scene appear unprecedentedly alive.1
• Emotional Intensity: The sculpture captures the most transitory state of St. Teresa of Ávila’s spiritual ecstasy, imbuing the marble with a passion that dispels the viewer's resistance to the divine miracle.12
