The mannerist and Baroque style interiors of Jesuit churches in the 16th and 17th century often included such trompe-l'œil ceiling paintings, which optically "open" the ceiling or dome to the heavens with a depiction of Jesus', Mary's, or a saint's ascension or assumption. An example of a perfect architectural trompe-l'œil is the illusionistic dome in the Jesuit church, Vienna, by Andrea Pozzo, which is only slightly curved but gives the impression of true architecture.
