The word "gargoyle" comes from a French word "gargouille"
which means "gargle" or "throat."
The
type of stone used by builders during the middle ages could be damaged by
constant exposure to rain. As such, the gargoyles were designed to remove
the rain water away from the building. With this picture, you are looking
at the gargoyle from above. Notice the gutter that runs along the back and
empties out through the throat of the stone creature.
In
addition to the practical use of removing water away from the building,
gargoyles were also used to incorporate pagan imagery into church
teaching. During the middle ages, the church was heavily involved in
converting people from pagan religions to Catholicism. Seeing some
recongnizable images from their customs and traditions helped in the
transition of these illiterate people to Catholicism
After
hundreds of years of diverting water away from the cathedrals, many
gargoyles have themselves been damaged by the water. Work to restore the
gargoyles to their original look is ongoing.
