Gargoyle n : a name
given to a grotesque carving which is usually in the form of a human or
animal mouth, head or body, projecting from the gutter of a
building. This type of carving is often found in Gothic architecture
and its practical function is usually to act as a spout or drain to
channel away rainwater. The grotesque nature of the carving is also
thought to serve as a frightening deterrent to ward off bad luck or
evil spirits.
