There are occaisional examples of mythical beings or objects illustrated in a coat of arms, either as an image upon the shield, or as a supporter, and the being Cupid is an example of this. Any meaning must really be ascribed from the charateristics of that object, nothing additional is added through their heraldic use. The Symbolisms of Heraldry, W.
