Stained Glass as Symbol

Stained glass is a powerful symbol on many levels:

• It is the boundary between man's temples and the outside world, transforming ordinary light into brilliant, iconic imagery;
• Although it is richly moving, and religious in intent, stained glass is the work of a master craftsman, commissioned by fallible humans, who may have political as well as spiritual motives;
• Stained glass is fragile, and can be easily shattered by anyone willing to throw the first stone.

These symbolic attributes will resonate through the story. In fact, Stained Glass is in part about the rich symbolism of church art.

Things I don't know about Stained Glass:

• How is it made (the processes of tinting, cutting, assembling)?
• Where would a stained glass window of high quality be manufactured?
• How would it be packaged and shipped?
• Who is the artist (he will become a main character in the novel)?
