Although many of these canvas prints arise from images captured inside churches and cathedrals, stained glass windows exist in many forums. Stained glass windows are a form of aged art and first appeared in rich Roman homes in the first century AD. In creating stained glass, artists started by melting sand and potash and then introduce metallic oxide powders to create various colors. The symbolism goes further than the overt shapes readily seen in the sunlight, but rather each color represents additional meaning. Red often symbolizes the blood of Christ, green represents growth and rebirth while blue for heaven, hope, and piety. This gallery shares all stained-glass windows wherever they may be found.
