The two central sculptural figures of the swooning nun and the angel with the spear derive from an episode described by
Teresa of Avila, a mystical cloistered Discalced Carmelite reformer and nun, in her autobiography,
The Life of Teresa of Jesus. Her experience of religious ecstasy in her encounter with the angel is described as follows: The group is illuminated by natural light which filters through a hidden window in the dome of the surrounding aedicule, and underscored by gilded stucco rays. Teresa is shown lying on a cloud indicating that this is intended to be a divine apparition we are witnessing. Other witnesses appear on the side walls; life-size
high-relief donor portraits of male members of the Cornaro family, e.g. Cardinal Federico Cornaro and Doge
Giovanni I Cornaro, are present and shown discussing the event in boxes as if at the theatre. Although the figures are executed in white marble, the aedicule, wall panels and theatre boxes are made from coloured marbles. Above, the vault of the chapel is frescoed with an illusionistic cherub-filled sky with the descending light of the
Holy Ghost allegorized as a dove. The art historian
