This is the "Corpus Christi" window from St. Bridget's Church. It is one of twelve windows, each representing an event from the liturgical calendar.
This description from church documents: "This symbol seeks to illustrate the vineyard of the Church. The center illustrates the wine press, also indicating the altar on which the transition of the wine into the Blood of Christ takes place. The mystical wine streams for us from the altar in the Mass and provides a continuous stream of heavenly grace to the faithful."
I've returned to the church several times to photograph the windows, altars, and many, many details. A couple of additional trips may be necessary, but most of the photography is complete. Now, the effort of turning the photos into finished work begins.
