chimera

In architecture, a chimera, or chimère, is a term used for any grotesque, fantastic, or imaginary beast incorporated into decoration. These often appear as decorative elements on buildings, such as those found on Notre-Dame in Paris, though they are distinct from gargoyles, which are functional waterspouts. The term originates from Greek mythology, where a Chimera was a fire-breathing monster composed of a lion, goat, and dragon. This mythological creature has led to the word "chimera" also being used to describe any illusion or fabrication of the mind, or an unrealizable dream.12345
