On one side of the church dome’s vault, the death of St. Teresa is depicted, crowning her path of mystical love and martyrdom. This composition of the dome is based on an engraving by A. van Westerhout. In the lower part of the vault, St. Teresa is shown with a cross, supported by sisters and surrounded by brothers and parents. Above her, upon the clouds that fill the entire area of the vault, Christ is painted on the left side, reaching out His hand to her. On the other side, a heavenly multitude of people dressed in light is depicted. Between St. Teresa and Christ, within a stream of light, the Holy Spirit can be discerned in the form of a dove. The commentary on A. van Westerhout’s engraving states: “St. Teresa, burning with the fire of divine love, at the moment when she most fervently yearned for her Bridegroom who was close at hand, breathed forth her soul in the form of a dove of the purest whiteness.”
On the other side of the dome’s vault, the apotheosis of St. Teresa is portrayed. Supported by angels, the saint glides through the clouds. This part of the dome’s composition is also based on an engraving illustrating St. Teresa’s biography by A. van Westerhout, the inscription at the bottom of which declares: “St. Teresa, embracing the vastness of heaven in her thoughts, lifted up in soul and body into the air, deserved to be among the inhabitants of heaven.”
