In medieval times, great church were constructed to honor God. These churches were adorned with all manner of artwork, all designed to honor the heavenly God. During the construction of the churches and cathedrals, a new art form developed - the stained glass window.
A stained glass window is a bunch of different colored pieces of glass that actually made a picture. In medieval times, sometimes they were just large pieces of colored glass in pleasing geometric shapes. Mostly though, they were designed to show a scene from the Bible.
These beautiful windows provided light for the interior of the church in a way that also reinforced the idea that the church was a place to worship the Christian god.
