Focus on this artwork and explore the History.
The painting was produced as the high-altarpiece for the church of Santa Maria in Vallicella in Rome (also known as the Chiesa Nuova, or "New Church." Its name refers to an ancient miraculous icon of the Nicopeia (bringer of victory) or Kyriotissa (enthroned) type known as the Madonna vallicelliana. Rubens reconstructed this image, surrounded by concentric circles of adoring angels and cherubs. On a copper plate placed over the Madonna della Vallicella, Rubens painted an additional Madonna with the Baby Jesus Giving Benediction that mirrors the sacred icon it covers. It's possible to raise the copper plate with a mechanism of pulleys and cords. In the central panel, space seems to expand out of the confines of its frames, a common theme in Baroque painting.
Rubens made a first version on canvas, but it must not have satisfied his clients for how light glared on its surface. So, he painted a new version on a slab of slate, a material with different reflective properties that eliminated the initial inconvenience. 
In the altar niche, Madonna della Vallicella forms a triptych with two other paintings on chalkboard panels that are placed on the nearby walls. A painting of Pope Gregory I and Papias and Maurus on the left and a painting of the saints Flavia Domitilla, and Nereus and Achilleus on the right. The Chiesa Nuova also possesses reliquaries of the depicted saints. The choice of the paintings in the triptych perhaps suggests that Rubens was influenced by an analogous composition choice made by Annibale Carracci in the Chapel Salviati of San Gregorio Magno al Celio for Saint Gregory at Prayer only a few years before.Rubens, in fact, distanced the two side paintings of saints from the central altar of the church. The side paintings are therefore turned toward the central panel with the venerated Madonna della Vallicella. Their placement directs the devotional gazes of Pope Gregory and Saint Domitilla toward the altar. The paintings of the Chiesa Nuova are the only works Rubens made in Rome that remained in the original locations.
