The Church of Saint Ignatius Loyola Bapistery
At the left hand side of the church facing the altar is the baptistery (from Wikipedia: "In Christian architecture the baptistry or baptistery is the separate centrally-planned structure surrounding the baptismal font.") composed of a half-drum surmounted by a semi-dome. This was the first part of the church’s interior to be decorated and clearly no expense was spared in the creation of what is undoubtedly the most precious unit in the church according to the Saint Ignatius Loyola website.
Tiffany Glass and Decorating Company created the baptistry’s semi-dome. “Composed of irregularly faceted glass slags referred to as “jewel” glass in the Tiffany lexicon, the dome suffuses this special precinct of the church with brilliant and sparkling light. At the apex of the design is a dove representing the Holy Spirit; rising from the waters of the font under this image symbolizes God’s claiming the newly baptized as his beloved child in the same way that Jesus was publicly claimed by God as His beloved Son on whom His favor rests (Mt. 3:17).”
