The studios that produced the  stained glass windows in the church, including the nave windows illustrated here, are unknown due to flooding that destroyed many church records. Henry Swiatek, Jr. opines that the nave windows are European, probably German. 

All the windows are two-panel windows with rounded arches united by a semicircle. All the windows are in the pictorial Renaissance style of the late-nineteenth and early-twentieth centuries. They are heavily painted in enamel on glass and are rich in color with large realistic figures heavily painted in rich and dark colors.  The Renaissance style window is three-dimensional, an effect aided by the landscape in the background.

Illustrations below are of windows starting near the front of the church (altar).  The theme is Biblical Scenes of Jesus, in contrast to the east nave where Saints are featured.
